Abstract:
Keynote paper presented at the International Leucaena Conference, 1‒3 November 2018, Brisbane, Queensland, Australia.To effectively utilize sterile hybrids of leucaena, efficient protocols for vegetative propagation are needed that meet different user requirements and capabilities. We developed and compared methods for propagating several sterile hybrids of leucaena and compared them with each other and with propagation via seeds for variety K636. Methods included air-layers, rooted cuttings, grafting and tissue culture (micropropagation). All methods required 14‒20 weeks from generation of new shoots on the stock plant to production of rooted plantlets ready to outplant as compared with 6‒8 weeks for seedlings of K636. Successful rooting was highest for air-layers and rooted cuttings. Grafting had lower success owing to a higher skill requirement for the propagator. Tissue culture showed promise, but use of field-grown material was limited by microbial contamination of propagation media. Rooted cuttings are the best option presently for operational-scale propagation, but the method requires a mist system or a carefully controlled non-mist environment. If an effective method can be developed, grafting of young shoots onto a seedling rootstock is an alternative that retains the advantages of a seedling tap root and requires fewer resources than rooted cuttings or tissue culture.

Abstract:
Next-generation biomass feedstocks are needed to optimize sustainability in a wide range of soils and climates. Species that has been recently noticed in Europe is Virginia fanpetals (Sida hermaphrodita L. Rusby). A critical question with research of this species is its field propagation. A long-term (2003–2012), field experiment was conducted to determine the impact of propagation method on yields and productivity this species. The hypothesis was higher yields of S. hermaphrodita biomass from vegetative propagations than from generative propagations, also over the long term. On average, from first 10 years of lifespan of Virginia fanpetals (2003–2012), biomass dry matter (DM) yields were significantly higher by vegetative propagation (16.8 Mg ha–1) as for generative (10.9 Mg ha–1). The average gross energy yield obtained by the vegetative propagation reached 304 GJ ha–1 while by the generative propagation was 196 GJ ha–1. The determined heat of combustion reached 18.1 GJ Mg–1 DM, the ash content was 28 g kg–1, and the nitrogen (N), sulphur (S), and chlorine (Cl) contents were 1.9 g kg–1, 0.52 g kg–1 and 0.23 g kg–1, respectively, regardless of propagation methods.

Abstract:
More than 70% of the ornamental plant species grown in Indian gardens are of exotic origin, which directly or indirectly affect the existence of indigenous vegetation of the country. In the exploration to find out the possibilities of the still to be exploited indigenous species in gardens, Gymnostachyum febrifugum Benth. a herbaceous plant endemic to southern Western Ghats of India, is systematically evaluated here for its aesthetic potential. Very poor percentage of seed germination was found the major cultivation constrain. The highly condensed stem restricts vegetative propagation also. A successful vegetative propagation method using single noded stem sections and node splits with single axillary buds is developed. Being vegetative propagation means, it also helps to retain the selected desirable qualities uniformly through generations.

Abstract:
Dipterocarpaceae dominate plants of tropical forests, and their wood is exploiting until it's been rare plants. Conservation through generative propagation has several problems, and vegetative propagation then being as an alternative. This study has two purposes that to understand the history of distribution of Dipterocarpaceae and do research about the development of vegetative propagation techniques that apply for Dipterocarpaceae. This study was using a systematic review method. Commonly, vegetative propagation techniques that have been applied are cuttings and culture in vitro but other vegetative techniques have not to use yet. Research on the vegetative propagation of Upuna and Parashorea has not been available. Cutting is the most propagation technique used and has a good effect on several species of Dipterocarpaceae. Culture in vitro techniques have been used for several genus and need further research. Keywords: conservation, dipterocarpaceae, rare tree, systematic review, vegetative propagation

Abstract:
Piperaceae species of forest remnants of Maringá, Paraná, Brazil present vegetative propagation through root or stem (stolon). This reproduction type was verified in Piper amalago L., P. arboreum Aublet, P. xylosteoides (Kunth) Steud., Peperomia parnassifolia Miq. and Ottonia martiana Miq. Root and stem branches of these species were analyzed anatomically. Results indicated that the vegetative propagation in Piperaceae should be studied in other forests. New and additional studies should be made if the structural variations were induced environmentally or fixed genetically.

Abstract:
This study was carried out at the Institute of Terrestrial Ecology (ITE), Bush Estate, Scotland, and at the Centre for Tropical Agricultural Research and Education (CATIE), Turrialba, Costa Rica, from December 1989 to September 1993. The work concentrated on two hardwood species native to Central America, Albizia guachapele (Kunth) Dug, and Cordia alliodora (Ruiz & Pavon) Oken. The main objectives of the study were to determine the effects of physiological factors on the rooting ability of both species and identify the optimal conditions for root initiation in leafy, stem cuttings using non-mist propagators. The study focused on some of the factors, both pre- and post-severance, generally accepted as having a crucial influence in determining the rooting ability of leafy cuttings. These included the stockplant growth environment, cutting origin, cutting foliar area, auxins, rooting media and propagation environment. Discussions are presented on the effects of these factors on cutting morphology and physiology, and their influence on the process of adventitious root formation. The practical implications for the propagation of both species and for further research are also discussed.

Abstract:
A series of laboratory and greenhouse experiments were designed with the objective of determining effective methods of vegetatively propagating selected woody riparian species for use in restoration of Southwestern riparian habitats. Cuttings from four major southwest riparian species including Fremont Cottonwood (Populus fremontii), Goodding Willow (Salix gooddingii), Arizona Sycamore (Platanus wrightii), and Arizona Walnut (juglans major) were collected along the Gila River in western New Mexico. Propagation studies with hardwood and root cuttings were performed. Results from these studies determined that Fremont Cottonwood and Goodding Willow could be readily propagated from dormant stem cuttings. Nodal explants from the laboratory -grown Arizona walnut seedlings were tissue -cultured in order to develop a method to mass produce this difficult to propagate species. A nutrient and hormone solution was formulated that resulted in shoot proliferation of Arizona walnut explants in vitro.

Abstract:
Two methods of vegetative propagation, stem cuttings under mist and air layering, were examined for the 'Desert Museum' hybrid palo verde and species of Cercidium, Parkinsonia, and Prosopis. Basal cuttings of 'Desert Museum' gave higher rates of rooting than apical cuttings and showed better rooting in April than September. Two-node cuttings produced more rooted cuttings for an equal stem length than three- or four-node cuttings. Cuttings of six other species and hybrids of Cercidium and Parkinsonia, as well as six species and hybrids of Prosopis, were also successfully rooted. Indolebutyric acid (IBA) in the range of 2,500 to 5,000 ppm generally improved rooting compared with no IBA treatment. Bottom heat of 30 to 35°C was required for high rooting rates for all species. Air layers of Prosopis chilensis averaged 94% rooting using stem diameters of 8 to 10 mm. IBA at 5,000 ppm improved rooting by 70% over 0 ppm. Air layers of Cercidium, Parkinsonia, and other species of Prosopis were also rooted.

Abstract:
The thesis reports new studies on the factors affecting the rooting of single node leafy stem cuttings of Shorea leprosula, a Dipterocarp timber tree native to South East Asia. Several aspects of vegetative propagation were investigated including treatments of the stock plants from which the cuttings were taken, propagation systems and post-severance treatments to cuttings. Stock plants raised in 1 litre pots of forest top soil and sand (3:1), and fertilised every two weeks with 0.5 g per plant of NPK fertiliser (12%N:12%P2O5:17%K2O:2MgO + Trace elements) were suitable for production of cuttings. Cuttings from stock plants raised under low irradiance of 0 to 325 μmol photons m-2s-1 (nominally 10% full sunlight) produced higher rooting and more roots than those from a high irradiance of 0 to 722 μmol photons m-2s-1 (nominally 30% full sunlight). S.leprosula stem cuttings rooted equally well in the mist and non-mist propagation systems as long as a consistently low vapour pressure deficit (VPD) was maintained. A temporary increase in the VPD of more than 0.5 kPa at peak irradiance could be tolerated by S.leprosula cuttings. Cuttings also rooted equally well in media with either low or high water retaining capacity such as river sand, coconut fibre or a mixture of these two media. A diurnal irradiance of 0 to 360 μmol photons m-2s-1 was adequate for rooting but 0 to 98 μmol photons m-2s-1 resulted in low rates of net photosynthesis (Pn) and a much reduced rooting success. In the enclosed mist propagation system, misting every 1 hour with a 1 minute duration of spray, throughout the day and night, provided sufficient moisture to cuttings and maintained mean relative humidity of more than 90%. Cuttings planted in the same system with a 3 hour misting frequency tended to develop water deficit as indicated by low relative water content and stomatal conductance.

Abstract:
The objective of this study was to determine potential propagation of Arizona sycamore (Platanus wrightii) from cuttings for use in riparian revegetation projects. Cuttings gathered from trees in Superior, Arizona during Fall 1988 and Spring 1989, and from Madera Canyon near Tucson, Arizona in Fall 1989 were treated with various concentrations of indolebutyric acid (IBA). In all studies, numbers of rooted cuttings decreased when concentrations of greater than 5,000 ppm IBA were used. Cuttings from young trunk sprouts in Fall 1988 had a higher rooting frequency than cuttings from other source trees and produced the greatest number and the longest roots in Spring 1989. In Fall 1989, plastic pots with a 1:1 perlite:vermiculite media resulted in higher rooting frequencies than when peat was incorporated into the media. While cuttings in all studies successfully rooted in the greenhouse, no plants survived outplanting on a 160 m elevation floodplain. Propagation of Arizona sycamore is more difficult than that of Fremont cottonwood (Populus fremontii) of Goodings willow (Salix goodingii) but cuttings will root with careful attention in the greenhouse.

Abstract:
Pinus patula has for many years been the most important softwood species along the eastern regions of southern Africa but as a result of the pine pathogen, Fusarium circinatum, there have been serious establishment issues and difficulties in propagating P. patula from either seed or cuttings. In response to this threat, research has been conducted on the development of F. circinatum-tolerant P. patula and hybridising it with more tolerant Pinus species such as P. tecunumanii. Not enough hybrid seed can, however, be produced to replace P. patula seedling production. It has therefore become necessary to investigate the production of tolerant P. patula families and various P. patula hybrid alternatives through vegetative propagation. The suitability of P. patula hybrids to the current and future vegetative propagation systems, that is hedges in polythene bags with composted pine bark growing media and hydroponic sand beds. It is also necessary to determine what the ideal plant specifications for those hybrid cuttings being produced are in order to ensure good survival and stocking. The potential gains from high quality planting stock include optimum stocking and volume growth. While some plant quality work has been undertaken on P. patula seedlings there has not been any research into the plant quality specifications required for the successful deployment of P. patula hybrid cuttings. The objective of this study was thus to: investigate the propagation potential of these taxa in the two vegetative propagation systems, with natural infection by Fusarium circinatum; and to test the morphological plant quality specifications for Pinus patula x Pinus tecunumanii (low elevation, LE) rooted cuttings required for optimal survival and growth after planting. The taxa propagation investigation comprised two experiments; a taxa production experiment and a propagation system experiment. Experiments were carried out at the Sappi Shaw Research Centre located near Howick, South Africa (S29°28.53’ E30°10.75’). The taxa sele cted represented a range of predicted F. circinatum tolerance. Each experiment comprised 23 family treatments (across eight hybrid and pure taxa). A total of 2300 hedges were included in the taxa production experiment, planted in the current commercial standard which is composted pine bark growing media in black polythene bags. The propagation system experiment, compared two hedge system types, the hydroponic sand bed and current commercial standard. A total of 1200 hedges were included in this experiment. A pine mini-hedge system was employed to produce juvenile shoots for vegetative propagation in both experiments. Rooted cuttings were produced between October 2008 and June 2012. Over the 45 month period a total of 23 shoot harvests were set. All dying hedge plants were collected and sent for laboratory confirmation of infection by F. circinatum. Needle samples from 493 hedges across selected hybrid crosses and P. patula as well as all 714 hedges of P. patula x P. tecunumanii (LE) were submitted for DNA fingerprinting to confirm their hybrid status. Significant differences (p < 0.001) in mortality associated with F. circinatum were observed between the P. patula x P. tecunumanii (LE) hybrid (6%) and P. patula (19-23%). No significant differences in mortality associated with F. circinatum were observed within P. patula x P. tecunumanii (LE) families which ranged from zero to 15 percent. Significant mortality differences (p < 0.001) were observed between P. patula families which ranged from eight to 44 percent. The number of rooted cuttings produced, per hedge established, over the four year period was significantly better (p < 0.001) in the P. patula x P. tecunumanii (LE) hybrid (52) than in P. patula (29-33). Significant differences (p < 0.001) were also observed in the number of rooted cuttings produced per family, with P. patula x P. tecunumanii (LE) families ranging from 35 to 70 cuttings per hedge plant established and P. patula families between 20 and 42 cuttings. Over the four year duration of the trial all taxa showed increased productivity in hedges grown in a hydroponic sand bed system, which received more consistent fertilisation and yielded an average of 55 rooted cuttings per hedge, over those grown in polythene bags with composed pine bark medium which yielded 41 cuttings on average. To investigate the morphological plant quality requirements for Pinus patula x Pinus tecunumanii rooted cuttings, rooted cuttings aged between 2 and 23 months, from time of setting, were selected from multiple families to establish a plant quality field trial. Cuttings were grouped into five age treatments and planted in a randomised complete block design in 7 by 7 tree plots and with 6 replications. A total of 20 hybrid families were included. Cuttings were raised in 90ml inserts in a containerised system with composted pine bark growing medium. Plant quality measures were assessed across 1470 individual cuttings, with age being used as a grouping factor at field planting. The cutting quality parameters included in this study were; plant age, height, RCD, needle colour, root plug colonisation, visual presence of ectomycorrhizae and number of visible white root tips. Survival and growth for each individual cutting was recorded at one year after field planting. The ideal raising period for P. patula x P. tecunumanii (LE) cuttings, grown in a 90ml cavity was 10 months from setting. The ideal height for cuttings was 28-32cm and the ideal root collar diameter range was 3.5mm - 4.5mm. The root plug was optimal when no growing medium fell off the plug when extracted from the insert; the root plug was firm but not hard and the plug was well colonised with a high proportion of thin brown roots. It was optimal to have at least three or more actively growing white root tips present and visible evidence of ectomycorrhizae. Needles in the dark mid-green to dark green range were shown to be optimal. These plant quality recommendations were based on findings from a single trial site that experienced good planting conditions and good rainfall. As a result, the effects of significant water stress on the survival and growth of these cuttings was not adequately assessed and would require further testing. This study showed that the P. patula x P. tecunumanii (LE) hybrid is a feasible substitute for P. patula in both vegetative propagation systems, as it not only shows improved survival, through increased F. circinatum tolerance, but also improved productivity. It also showed that even under ideal planting conditions cutting age, height, root collar diameter, needle colour, root plug integrity and the number of white roots all had a significant effect on survival and growth of cuttings a year after field establishment.

Abstract:
Mango is one of the most important fruit crops. However, the biology of this fruit tree is under studied. The lack of genetic and genomic resources has limited progress in mango research and breeding. Several research groups have recently started developing genomic tools for mango by creating transcriptome and genomic data. Sexual reproduction in plants is the main pathway for the creation of new genetic combinations. In modern agriculture, breeders exploit the genetic diversity generated through sexual reproduction to develop elite cultivars; however, these cultivars require genetic stabilization before they are suitable for mass propagation for uniform crop production. In heterozygous plants such as fruit trees, vegetative propagation (cloning) is the primary path for the propagation of genetically uniform plants. Another natural plant mechanism that can create genetically uniform plants (clones) is apomixes. Apomixis is defined as asexual reproduction through seeds that lead to the production of clonal progeny whose genotype is identical to that of the mother plant. In fruit crops like citrus and mango, sporophytic apomixes result in polyembryony, where seeds contain multiple embryos, one of which is sexually originated, and the others are clones of the mother tree. As part of this research, the reference genome of mango was established as a basic platform for mango breeding and research. It was used to map two important mango traits fruit size and polyembryony. The draft genome 'Tommy Atkins' sequence was generated using NRGene de-novo Magic on high molecular weight DNA of 'Tommy Atkins,' supplemented by 10X Genomics long read sequencing to improve the initial assembly. The final 'Tommy Atkins' genome assembly was a consensus sequence that included 20 pseudomolecules representing the 20 chromosomes of mango. The availability of a genome enables the genetic dissection of important traits. We demonstrated the utility of the genome assembly and the 'Tommy Atkins' x 'Kensington Pride' map by analyzing fruit weight phenotypic data and identifying two QTLs for this trait.

Full text
Abstract:
This study documents impacts to the Fremont River that were initiated by the construction of Utah State Route 24 in 1962 within what is now Capitol Reef National Park (CARE). The highway and related river modifications led to an artificial abandonment of a 4000 ft long river meander, creation of a channel bed knickpoint (i.e., waterfall), and at least 9 ft of vertical incision into the underlying Navajo Sandstone. Channel incision also appears to have translated upstream, as we found a significant trend of a deeper channel immediately upstream of the knickpoint that transitioned to being wider and shallower upstream. The rate of upstream propagation of these geomorphic changes may be as high as 20 ft/yr, with ongoing and future incision threatening the stream-riparian system further. The knickpoint and its upstream propagation through a knickzone have also affected the Fremont River riparian vegetation community within the less frequently flooded incised reach by shifting it toward more dry-adapted species. In contrast, the channel in the less incised reference reach inundates its floodplain more frequently, has a higher mean vegetation abundance, and supports more wet-adapted species. Upstream propagation of a more deeply incised channel will likely continue through the Navajo Sandstone segment and into the more vulnerable alluvial segment upstream. Reactivation of the abandoned river meander to restore the Fremont River and its riparian corridor will require channel realignment to match elevations between the current and abandoned channels. Additionally, further upstream in a sub-reach where the highway has been repeatedly impacted by overbank flows, direct observations by park staff are supported by our hydraulic modeling indicating that the highway is inundated by flows of between 1000 and 1900 cubic feet per second, which are expected to occur every 2?5 years. Mitigation to improve flood resiliency and to alleviate river-highway conflicts may also be appropriate. Overall, this study?s findings can help inform current river management decisions, state highway corridor planning, and future river restoration efforts in CARE.

Abstract:
Date palm (Phoenix dactylifera L.) is the major fruit tree grown in arid areas in the Middle East and North Africa. In the last century, dates were introduced to new regions including the USA. Date palms are traditionally propagated through offshoots. Expansion of modern date palm groves led to the development of Tissue Culture propagation methods that generate a large number of homogenous plants, have no seasonal effect on plant source and provide tools to fight the expansion of date pests and diseases. The disadvantage of this procedure is the occurrence of off-type trees which differ from the original cultivar. In the present project we focused on two of the most common date palm off-types: (1) trees with reduced fruit setting, in which most of the flowers turn into three-carpel parthenocarpic fruits. In a severe form, multi-carpel flowers and fruitlets (with up to six or eight carpels instead of the normal three-carpel flowers) are also formed. (2) dwarf trees, having fewer and shorter leaves, very short trunk and are not bearing fruits at their expected age, compared to the normal trees. Similar off-types occur in other crop species propagated by tissue culture, like banana (mainly dwarf plants) or oil palm (with a common 'Mantled' phenotype with reduced fruit setting and occurrence of supernumerary carpels). Some off-types can only be detected several years after planting in the fields. Therefore, efficient methods for prevention of the generation of off-types, as well as methods for their detection and early removal, are required for date palms, as well as for other tissue culture propagated crops. This research is aimed at the understanding of the mechanisms by which off-types are generated, and developing markers for their early identification. Several molecular and genomic approaches were applied. Using Methylation Sensitive AFLP and bisulfite sequencing, we detected changes in DNA methylation patterns occurring in off-types. We isolated and compared the sequence and expression of candidate genes, genes related to vegetative growth and dwarfism and genes related to flower development. While no sequence variation were detected, changes in gene expression, associated with the severity of the "fruit set" phenotype were detected in two genes - PdDEF (Ortholog of rice SPW1, and AP3 B type MADS box gene), and PdDIF (a defensin gene, highly homologous to the oil palm gene EGAD). We applied transcriptomic analyses, using high throughput sequencing, to identify genes differentially expressed in the "palm heart" (the apical meristem and the region of embryonic leaves) of dwarf vs. normal trees. Among the differentially expressed genes we identified genes related to hormonal biosynthesis, perception and regulation, genes related to cell expansion, and genes related to DNA methylation. Using Representation Difference Analyses, we detected changes in the genomes of off-type trees, mainly chloroplast-derived sequences that were incorporated in the nuclear genome and sequences of transposable elements. Sequences previously identified as differing between normal and off-type trees of oil palms or banana, successfully identified variation among date palm off-types, suggesting that these represent highly labile regions of monocot genomes. The data indicate that the date palm genome, similarly to genomes of other monocot crops as oil palm and banana, is quite unstable when cells pass through a cycle of tissue culture and regeneration. Changes in DNA sequences, translocation of DNA fragments and alteration of methylation patterns occur. Consequently, patterns of gene expression are changed, resulting in abnormal phenotypes. The data can be useful for future development of tools for early identification of off-type as well as for better understanding the phenomenon of somaclonal variation during propagation in vitro.

Efficient screening of antibacterial genes by juvenile phase free technology for developing resistance to fire blight in pear and apple trees. United States Department of Agriculture, December 2008. http://dx.doi.org/10.32747/2008.7613881.bard.

Full text
Abstract:
Objectives: The original objectives of this project were to: Produce juvenile-free pear and apple plants and examine their sensitivity to E. amylovora; Design novel vectors, for antibacterial proteins and promoters expression, combined with the antisense TFL1 gene, and transformation of Spadona pear in Israel and Galaxy apple in USA. The original objectives were revised from the development of novel vectors with antibacterial proteins combined with the TFL-1 due to the inefficiency of alternative markes initially evaluated in pear, phoshomannose-isomerase and 2-deoxyglucose-6-phosphate phosphatase and the lack of development of double selection system. The objectives of project were revised to focus primarily on the development additional juvenile free systems by the use of another pear variety and manipulation of the FT gene under the control of several promoters. Based on the results creation of fire blight resistance pear variety was developed by the use of the juvenile free transgenic plant. Background: Young tree seedlings are unable to initiate reproductive organs and require a long period of shoot maturation, known as juvenile phase. In pear, juvenile period can last 5-7 years and it causes a major delay in breeding programs. We isolated the TFL1 gene from Spadona pear (PcTFL1-1) and produced transgenic ‘Spadona’ trees silencing the PcTFL1 gene using a RNAi approach. Transgenic tissue culture ‘Spadona’ pear flowered in vitro. As expected, the expression of the endogenous PcTFL1 was suppressed in the transgenic line that showed precocious flowering. Transgenic plants were successfully rooted in the greenhouse and most of the plants flowered after only 4-8 months, whereas the non-transformed control plants have flowered only after 5-6 years of development. Major achievements: Prior to flower induction, transgenic TFL1-RNAi ‘Spadona’ plants developed a few branches and leaves. Flower production in the small trees suppressed the development of the vegetative branches, thus resulting in compact flowering trees. Flowering was initiated in terminal buds, as described for the Arabidopsis tfl1 mutant. Propagation of the transgenic TFL1-RNAi ‘Spadona’ was performed by bud grafting on 'Betulifolia' rootstock and resulted in compact flowering trees. The transgenic flowering grafted plants were grown in the greenhouse under a long photoperiod for one year, and flowered continuously. Pollination of the transgenic flowers with ‘Costia‘ pear pollen generated fruits of regular shape with fertile F1 seeds. The F1 transgenic seedling grown in the greenhouse formed shoots and produced terminal flowers only five months after germination. In addition, grafted F1 transgenic buds flower and fruit continuously, generating hybrid fruits with regular shape, color and taste. Several pear varieties were pollinated with the transgenic TFL1-RNAi ‘Spadona’ pollen including `Herald Harw` that was reported to have resistance to fire blight diseases. The F-1 hybrid seedlings currently grow in our greenhouse. We conclude that the juvenile-free transgenic ‘Spadona’ pear enables the development of a fast breeding method in pear that will enable us to generate a resistance pear to fire blight. Implications: The research supported by this grant has demonstrated the use of transgenic juvenile free technology in pear. The use of the juvenile free technology for enhancement of conventional breeding in fruit tree will serve to enhance fast breeding systems in pear and another fruit trees.

The cassava seed system in Nigeria: Opportunities and challenges for policy and regulatory reform. International Potato Center, 2020. http://dx.doi.org/10.4160/23096586rtbwp20202.

Full text
Abstract:
In many African countries south of the Sahara, farmers depend on the cultivation of vegetatively propagated crops (VPCs) for both consumption and commercial purposes. Yet yields for these crops remain at low levels due, in part, to the persistent use of low-quality planting material. Efforts to improve the quality of planting material exchanged in markets or through other channels are often hampered by the unique biological and economic characteristics of vegetative propagation—characteristics that distinguish VPCs from the major cereal crops that drive and shape the policy and investment choices made in many of these countries. This suggests that continued investment in new technologies and systems to produce, package, and distribute VPC planting materials will require customized policies and policy support if these systems are to supply farmers with quality planting material at any significant and sustained scale. This paper explores these issues in the context of the cassava seed system in Nigeria by drawing on (1) prior research, public policy documents, and government statistics; (2) key informant interviews and focus group discussions with seed system actors; and (3) a unique dataset from the 2015 Cassava Monitoring Survey of Nigeria (CMS). The paper examines the production and supply of cassava planting material, the influence of various quality assurance systems on production and supply, and the implications for smallholder farmers in Nigeria. We describe the market, non-market, and regulatory systems that shape the cassava seed market in Nigeria, focusing on effectiveness, influence, and reach. We then explore the ground realities—how farmers actually acquire and use cassava planting material—given the (weak) state of markets and regulation. This is followed by a discussion of alternative policy and regulatory approaches to managing and expanding the cassava seed system, emphasizing a more decentralized approach that prioritizes investment in innovative capacity at the community and enterprise levels.
