Abstract:

“Waimanalo Supersweet” will be released at the time of the 1992 ASHS meeting in Hawaii. A singlecross supersweet corn based on the brittle gene, “Waimanalo Supersweet” represents over 50 generations of inbreeding and backcrossing in Hawaii. Successive projects involved the development of sugary inbreds and their conversion to Mv. Ht. Rp-d and brittle genes. The inbred parents have very limited temperate germplasm and are relatively daylength sensitive. This single cross hybrid and its related 3X (“Hawaiian Supesweet #10”) and OP variety (“Hawaiian Supersweet #9”) show tolerance to Puccinia sorghi rust and Fusarium Moniliforme kernel rot greatly in excess of commercial sweet corns to which they have been compared, and they have performed capably throughout the tropics. Available data on pest tolerance, growth and quality will be summarized.

Abstract:

Insect resistance in vegetable crops carries a new urgency as insecticide availability and usage become more restricted. The European corn borer (ECB) long has been the most costly sweet corn pest in the northern states, with corn earworm (CEW) and southwestern stalk borer most serious farther south. Resistance to ECB and CEW, as developed by classical methods, will be discussed. Newer methods (such as RFLPs) should speed transfer of this resistance to commercial stocks, and also facilitate transfer of resistance from other species. Gene modification and endophyte exploitation are longer-term possibilities. Resistance must be free from association with undesirable traits, such as long silk channel length (r = 0.3 to 0.4), unless consumer and processor specifications change.

Abstract:

AbstractIntercropping is an agricultural system widely practiced in the tropics and becoming more widespread in temperate regions. The vast majority of varieties currently grown in intercrop have been developed in and for monoculture, although some breeding programs specifically focused on intercrop systems have been initiated. It is not clear if selection in monoculture is adequate to identify varieties adapted to intercrop, nor is it clear if varieties selected for intercrop performance with one companion will be adapted to another crop combination. The aims of this study were to determine the extent to which selection of corn in monoculture would identify types adapted to growth in corn—bean or corn—clover intercrop, and to determine how selection in one of the intercrops (corn—bean or corn—clover) would compare with selection in the other. The corn used consisted of two groups that had been selected in monoculture, and two that had been selected in corn—bean intercrop. All groups were evaluated in monoculture, corn-bean intercrop, and corn—clover intercrop. Analysis of variance showed that the ranking of the four selection groups was not significantly different when the two intercrops were compared, but was significantly different (P < 0.05 for comparison of clover intercrop and monoculture, and P = 0.07 for comparison of bean intercrop and monoculture) when either of the two intercrops was compared with monoculture. Correlation analysis of corn traits and corn yield in the three cropping systems revealed more similarities between the intercrops than between either intercrop and monoculture. Plant height and leaf area index were more strongly negatively correlated with days to flower in both intercrops than in monoculture. Correlation analysis also revealed some differences between the intercrops, particularly with bean and clover yields. Clover yields were not adversely affected by early growth and maturity of corn, but bean yields were. We conclude that selection of corn in monoculture is not ideal when lines adapted to cornclover intercrop or corn—bean intercrop are desired. Furthermore, selection in either intercrop will identify corn types adapted to the other, as early vigor and maturity allow best corn performance in both crop combinations. Thus, individualized breeding programs may not be required to adapt a crop to growth in association with relatively different companions.

Abstract:

The development of the subprogram “Maize Breeding and Seed Production Development” within the framework of the Federal Scientific and Technical Program for the Development of Agriculture for 2017–2025 determines the necessity for intensive technical equipping of the industry with specialized domestic breeding equipment.(Research purpose) To analyze the technical level of devices for the work mechanization in maize selection, variety testing and primary seed production, to identify the main directions of agricultural machinery development.(Materials and methods) The authors studied materials published in periodicals, statistics of the Ministry of Agriculture of Russia and the Federal State Statistics Service, information materials of Russian and foreign companies, the regulatory framework. They used methods of complex structural-dynamic analysis and an expert-analytical method of processing information.(Results and discussion) The authors established the presence of domestic selection and seed production import dependence on foreign equipment supplies: with equipping of breeding institutions with mechanization facilities about 50 percent the foreign machinery and equipment share reached 70 percent. They identified the main problems in the corn selection and seed production mechanization. The first problem was the lack of domestic seeders for sowing at the first stage of selection, having the following parameters: traction class – 0.2; row spacing – up to 0.7 meters, the sowing sections number – 1 and 2; the distance between the coulters is 0.7 meters. The second problem was the domestic seeders for sowing shortage at the second stage of selection with the required parameters: traction class – 0.6; 1.4; 2.0; row spacing – 0.7 meters; the sowing sections number – 4 and 6; distance between extreme openers – 2.1; 3.5 meters. The third problem was the lack of domestic harvesting equipment that met the requirements: row spacing – 0.7 meters; working width – 1.4 and 2.8 meters; width – 1.8 or 3.2 meters; turning radius – 7.5 meters.(Conclusions) The technical level of devices for the work mechanization in selection, variety testing and maize primary seed production didn’t meet the parameters of an integrated approach in the justification and specialized equipment development. The authors noted the necesity to develop the following domestic technical means: sowing machines for sowing nurseries of the first stage; markers; small-sized sprayers; two-row mover-shredder of corn male parent plants.

Abstract:

The cultivation of alternative crops has an important role in world agriculture. Their market share is continuously growing in the food industry sector. In the present study, we show the cultivation and breeding perspectives of ornamental and blue corn. There exists possibility to cultivate ornamental corn in Hungary. There are many cultivars of ornamental corn, with various kernel colors, husks, stalks and leave colors. Blue corn is unique among other corns. Blue corn higher in protein, iron and zinc than commercial dent corn. Pests affective ornamental and blue corn are the same as those of other commercial corns. Ornamental and blue corns need to be grown a minimum of 500 m away from commercial yellow dent corn to minimize any cross pollination which may result in off-color kernel. Our aim in the presentation of this review was to broaden Hungarian literature.

Abstract:

Soybean yield gain over the last century has been attributed to both genetic and agronomic improvements. Recent research has characterized how breeding efforts to improve yield gain have also secondarily impacted agronomic practices such as seeding rate, planting date, and fungicide use. To our knowledge, no research has characterized the relationship between weed–soybean interference and genetic yield gain. Therefore, the objectives of this research were to determine whether newer cultivars would consistently yield higher than older cultivars under increasingly competitive environments, and whether soybean breeding efforts over time have indirectly increased soybean competitiveness. Field research was conducted in 2014, 2015, and 2016 in which 40 maturity group (MG) II soybean cultivars released between 1928 and 2013 were grown season-long with three different densities of volunteer corn (0, 2.8, and 11.2 plants m−2). Soybean seed yield of newer cultivars was higher than older cultivars at each volunteer corn density (P<0.0001). Soybean seed yield was also higher in the weed-free treatment than at low or high volunteer corn seeding rates. However, soybean cultivar release year did not affect late-season volunteer corn shoot dry biomass at either seeding rate of 2.8 or 11.2 seeds m−2. The results indicate that while soybean breeding efforts have increased yield potential over time, they have not increased soybean competitiveness with volunteer corn. These results highlight the importance of other cultural practices such as planting date and crop row spacing for weed suppression in modern soybean production systems.

Abstract:

The red-winged blackbird (Agelaius phoeniceus) population in southwestern Quebec more than doubled between 1966 and 1981, apparently in response to increased corn production. In southwestern Ontario less pronounced increases in blackbirds and corn production also occurred. Although larger blackbird populations have been responsible for greater crop damage, it is the waste corn left in fields by mechanical harvesters that supports the increased blackbird population. The increased availability of waste corn during the spring and summer (breeding season) was likely most important in allowing the blackbird population to grow. This conclusion is supported by our census of blackbird populations in 38 counties in southwestern Quebec during the breeding season, which indicated a strong positive correlation between blackbird abundance and corn production in a county. Although corn production explains much variation in the size of blackbird populations, other factors such as the availability of breeding habitat and the spatial distribution of habitats (landscape heterogeneity) may be responsible for additional variation.

Abstract:

Significant yield reduction and effect on almost every aspect of the plants by insect pests have been a mega problem in agricultural crops. Scientist tackle with many challenges to develop highly efficient techniques either through conventional breeding or modern genetic engineering to understand the mechanism of resistance and its application for benefit of human kind. Antibiosis, antixenosis and tolerance are the resistance mechanisms which have been developed for successful control of economically important insect pests in corn. Plant morphology and allelochemicals, induced resistance, callus tissue culture and genetic transformation were used as major tools to advance resistance by corn breeders. Insect pest resistant corn has been attributed for social, economical as well as environmental benefits. However, outcome of these achievements are not reflected due to low use of insect resistant corn by farmers in many developing countries of the world.

Abstract:

Corn breeding can be successful only on a broad base of genetic material. The expansion of breeding aims includes the research of germplasm materials. In our experiments, we examined 11 blue, purple and red exotic corn varieties on two locations in Hungary. We conducted a complex study to obtain more information. We studied several morphological and phenological features and determined the most important qualitative parameters (protein, fat, ash). We applied the Tassel Area Index (TAI) under Hungarian conditions and compared it with the pollen producing ability of different genotypes. Results show that there are great opportunities in exotic corn varieties. Their quality exceeds that of the yellow ones in many cases. There are significant differences in yield and nutritional parameters. The favorable nutritional composition is not coupled with great productivity. Based on their flowering time and their agronomical features, they can be cultivated under Hungarian conditions as well. They match the new breeding aims, so they can be used as functional food or energy plants. With their high pollen producing ability and TAI, they can be utilized as markers in future pollen research.

Abstract:

Phenotyping provides important support for corn breeding. Unfortunately, the rapid detection of phenotypes has been the major limiting factor in estimating and predicting the outcomes of breeding programs. This study was focused on the potential of phenotyping to support corn breeding using unmanned aerial vehicle (UAV) images, aiming at mining and deepening UAV techniques for comparing phenotypes and screening new corn varieties. Two geometric traits (plant height, canopy leaf area index (LAI)) and one lodging resistance trait (lodging area) were estimated in this study. It was found that stereoscopic and photogrammetric methods were promising ways to calculate a digital surface model (DSM) for estimating corn plant height from UAV images, with R2 = 0.7833 (p < 0.001) and a root mean square error (RMSE) = 0.1677. In addition to a height estimation, the height variation was analyzed for depicting and validating the corn canopy uniformity stability for different varieties. For the lodging area estimation, the normalized DSM (nDSM) method was more promising than the gray-level co-occurrence matrix (GLCM) textural features method. The estimation error using the nDSM ranged from 0.8% to 5.3%, and the estimation error using the GLCM ranged from 10.0% to 16.2%. Associations between the height estimation and lodging area estimation were done to find the corn varieties with optimal plant heights and lodging resistance. For the LAI estimation, the physical radiative transfer PROSAIL model offered both an accurate and robust estimation performance both at the middle (R2 = 0.7490, RMSE = 0.3443) and later growing stages (R2 = 0.7450, RMSE = 0.3154). What was more exciting was that the estimated sequential time series LAIs revealed a corn variety with poor resistance to lodging in a study area of Baogaofeng Farm. Overall, UAVs appear to provide a promising method to support phenotyping for crop breeding, and the phenotyping of corn breeding in this study validated this application.

Abstract:

Corn cropping for silage, due to the plant material exportation, intercropping with forage provides greater ground cover and straw formation for the Direct Planting System (DPS) continuity. The objective of this study was to evaluate corn production for silage in DPS intercropped with four forages (Urochloa brizantha cv. Marandu, U. ruziziensis cv. Ruziziensis, Panicum maximum cv. Tanzânia and P. maximum cv. Áries). We applied three sowing methods (in row together with corn fertilizer; by no-till sowing simultaneously to corn sowing and at V4 corn stage) and corn without intercropping. The experiment was conducted in autumn/ winter of 2010, in Selvíria - MS, in a randomized block design in factorial arrangement (4 x 3 + 1) and 4 replications. For corn, we evaluated plant height, basal stem diameter, initial and final stand and silage production and for forage dry matter production. Morphological characteristics and corn yield were not affected by intercropping when compared to sole corn crop. Forage dry matter production sown in corn row with fertilizer is a highlight, which in addition to providing greater productivity, harnesses the operation during sowing.

Abstract:

Corn (Zea mays L.) is an important cereal crop indigenous to the Americas, where its genetic biodiversity is still preserved, especially among native populations from Mesoamerica and South America. The use of metabolomics in corn has mainly focused on understanding the potential differences of corn metabolomes under different biotic and abiotic stresses or to evaluate the influence of genetic and environmental factors. The increase of diet-linked non-communicable diseases has increased the interest to optimize the content of bioactive secondary metabolites in current corn breeding programs to produce novel functional foods. This review provides perspectives on the role of metabolomics in the characterization of health-relevant metabolites in corn biodiversity and emphasizes the integration of metabolomics in breeding strategies targeting the enrichment of phenolic bioactive metabolites such as anthocyanins in corn kernels.

Abstract:

The germplasm evaluation techniques in resistance breeding programs may improperly characterize insect damage. For example, the relationship between economic damage levels and biological damage levels may not be linear as some techniques assume. Most commercial sweet corn hybrids are highly susceptible to European corn borer (ECB), Ostrinia nubilalis Hübner, ear feeding. Genotype variation for ECB damage in our breeding program traditionally has been identified by using a 1 (no damage) to 9 visual rating scale that combines damage levels, damage site on the ear, and the economic consequences of ECB feeding for the processing industry. An alternative 1 to 5 scale based solely on a visual percentage assessment of ear feeding damage was developed and compared to the traditional scale. Seven entries, including moderately resistant and susceptible hybrids and inbred lines of the ECB ear resistance breeding program, were evaluated with both scales in 1994 and 1995 at two locations. Inbred MN3002, Hybrid MN3004, `Apache', and `More' had lower mean damage ratings (3.4, 3.4, 3.6, 3.8, traditional vs. 2.4, 2.2, 2.2, 2.3, alternative, respectively) than `Jubilee', Inbred W182E, and Inbred MN3003 (5.3, 5.6, 7.3, traditional vs. 3.3, 3.0, 4.2, alternative, respectively). Thus, four entries were classified as moderately resistant (3.0 to 4.0 traditional vs. 2.0 to 3.0 alternative) and three entries were classified as susceptible (>4.0 traditional vs. >3.0 alternative). Individual entry ranks varied by scale, but this did not alter resistance classifications. Although the nine traditional ratings were based on economic consequences and the five alternative ratings were based strictly on feeding levels excluding damage location, both scales effectively identified genotypes historically classified as moderately resistant and susceptible. The value of scales is often questionable for many situations and should be considered prior to evaluation.

Abstract:

Sweet corn differs from field corn in many important traits. So its breeding although includes some standard procedures demand application of techniques that are important for determining special traits, all because of the specificity of its usage. Application of molecular markers becomes almost a necessity for the breeding of sweet corn, especially because this is the type of maize in which still no definitive heterotic patterns have been determined. So getting to know genetic divergence of the sweet corn inbred lines is of great importance for its breeding. In this paper we analyzed genetic similarity of six sweet corn inbreds based on SSR markers. 40 SSR primers were used in DNA amplification. Results were compared and correlated with the data on specific combining ability, obtained by the diallel analysis. The results of SCA were in concurrence with genetic similarity. Values of rank correlation coefficient were negative, indicating that more similar inbred lines had smaller estimates of SCA, and lines that were less similar had higher estimates of SCA. Rank correlation coefficient between SCA and GS according to Dice coefficient was between -0,16 and -0,57*.

Abstract:

The sweet corn market has been expanding in recent years and the trend is to maintain this growth, targeting mainly the export market. The goal was to evaluate the agronomic performance per se and hybrid backcrosses of four sweet corn populations and to estimate genetic parameters inherent in these populations, in order to achieve promising lines to obtain hybrids. The following genotypes were used for a test: the donor population sh gene, two recurring populations interpopulation hybrids of common maize, four sweet corn populations, and four sweet corn interpopulation hybrids. The traits evaluated were: plant height, stand, number of ears, prolificacy, number of grain rows, as well as average ear diameter, average diameter cobs, average husked ear length, average unhusked ear length, average unhusked ear weight, average husked ear weight, ear relationship, unhusked ear yield and husked ear yield. The backcross method was efficient for obtaining sweet corn populations with good agronomic performance. Because the sweet corn interpopulation hybrid presents agronomic performance similar toP8 x C8 interpopulation hybrid, it can be inferred that all sweet corn populations backcrossed are recommended for use in obtaining lines, in order to obtain productive hybrids, or even directly as hybrid trade after further assessments.

Abstract:

Genetic manipulation may not replace any conventional method in crop breeding programs, but it can be an important adjunct to them. Plant regeneration via tissue culture is becoming increasingly more common in monocots such as corn (Zea mays L.). In vitro culturability and regeneration ability of corn decreased as homozigosity increased, which suggested that these two attributes were controlled primarily by dominant gene action. Pollen (gametophytic) selection for resistance to aflatoxin in corn can greatly facilitate recurrent selection and screening of germplasm for resistance at a much less cost and shorter time than field testing. Integration of in vivo and in vitro techniques in maize breeding program has been developed to obtain desirable agronomic attributes, speed up the breeding process and enhance the genes responsible for them. The efficiency of anther and tissue cultures in most cereals such as maize and wheat have reached the stage where it can be used in breeding programs to some extent and many new cultivars produced by genetic manipulation have now reached the market.

Abstract:

The maize (Zea mays L. ssp. mays) has several related species, called teosinte, which are distributed in various subspecies of Zea and other genera. Among the different types of corn, sweet corn shows a great potential for human food. This type was originated from mutations, which increased the amount of polysaccharide in the endosperm. In Brazil there are populations of sweet corn, common maize and teosinte, however, little is known about their genetic variability. Hence, the aim of this present paper was to analyze the genetic variability in two populations of sweet corn (BR 400 and BR 402), two common corn (Pampa and Suwan) and teosinte, using microsatellite markers. The results showed a low intra-population genetic variability in populations of maize, and high variability for the population of teosinte, suggesting that the maize populations may have limitations in future cycles of breeding.

Abstract:

Trials were conducted in 1997 and 1998 to determine if there is a range of resistance to European corn borer [Ostrinia nubilalis (Hübner)] (ECB) in commercially available processing sweet corn (Zea mays L.). Twelve processing corn cultivars were tested in 1997 and 18 cultivars in 1998. About 40 first instar larvae of colony-reared ECB were used to infest plants in both whorl and silking stages of growth. At harvest, plants infested at the whorl stage were evaluated for numbers of larvae and larval tunnels, and length of larval tunnels. Plants infested at the silking stage were evaluated for number of larvae per ear and were rated for ear damage using a 9-point scale. Resistance rankings among cultivars were consistent between years and between silk- and whorl-infested plants. We conclude that there is a substantial range of resistance already present in processing sweet corn cultivars, and that resistance is probably a combination of both exclusion and suppression of feeding. Our findings have two immediate uses: incorporation into existing IPM programs and incorporation of identifiable resistance bearing cultivars into a long-term breeding program for resistance to ECB in sweet corn.

Abstract:

Modern sweet corn is distinguished from other vegetable corns by the presence of one or more recessive alleles within the maize endosperm starch synthesis pathway. This results in reduced starch content and increased sugar concentration when consumed fresh. Fresh sweet corn originated in the USA and has since been introduced in countries around the World with increasing popularity as a favored vegetable choice. Several reviews have been published recently on endosperm genetics, breeding, and physiology that focus on the basic biology and uses in the US. However, new questions concerning sustainability, environmental care, and climate change, along with the introduction of sweet corn in other countries have produced a variety of new uses and research activities. This review is a summary of the sweet corn research published during the five years preceding 2021.

Abstract:

The genes sugary1 (su1) and shrunken2 (sh2) are commonly used to produce sweet and super-sweet corn (Zea mays L.), respectively. In this work we compare corn borer [european corn borer (ECB) (Ostrinia nubilalis Hbn.) and pink stem borer (PSB) (Sesamia nonagrioides Lef.)] susceptibility in seven pairs of su1 and sh2 near-isogenic sweet corn inbreds (101t, C23, C40, C68, Ia453, Ia5125, and P39) and the relationship between corn borer resistance and vegetative phase transition. The seven pairs of near-isogenic inbreds were evaluated under corn borer infestation during 3 years in northwestern Spain. Differences among inbreds were significant for most of the traits, although resistance was partial. Ia5125su1 and C40su1 were the most resistant inbreds. Differences between a few pairs of near-isogenic su1 and sh2 strains were significant for some vegetative phase change and corn borer damage-related traits. Generally su1 strains flowered earlier, had a shorter juvenile phase, fewer PSB, and more ECB larvae than sh2 strains. However su1 and sh2 strains did not differ significantly for most traits related to phase transition and corn borer damage; notably ear damage was not significantly different between su1 and sh2 strains. These results suggest that theoretical and practical results of sweet corn (sugary1) breeding for corn borer resistance could be capitalized for super-sweet corn (shrunken2) breeding.

CO450 is a short-season early-maturing (average 71 d to flowering) corn (Zea mays L.) inbred line with excellent combining ability and superior resistance to eyespot (Aureobasidium zeae). This is the first inbred to be released from AAFC's eyespot resistance breeding program. CO450 also has moderate resistance to common rust, intermediate resistance to common smut and both fusarium and anthracnose stalk rot. Excellent hybrid yields and performance data were achieved when CO450 was crossed with stiff stalk inbreds such as MBS1130 and an Iodent inbred, MBS8148. CO450 also exhibited good performance at sites with 2400 CHU or less in combination with a very early inbred, CL30.

Abstract:

Development of sweet corn hybrids having resistance to ear feeding by the European corn borer (ECB) (Ostrinia nubilalis, Hübner) would save growers millions of dollars annually. Sweet corn breeding lines have been developed which show resistance to ear feeding. To determine whether resistance in these lines was heritable, testcrosses were made between 6 resistant lines and 2 susceptible inbreds. The testcrosses, resistant lines, susceptible inbreds, and Jubilee, a standard susceptible hybrid, were planted in randomized complete blocks replicated 8 times at each of 2 locations. Primary ears were infested, on the ear tip, at mid-silk (R3) with approximately 50 neonate larvae and were evaluated for damage 25 - 30 days later using a 9 point scale. The resistant parents and their testcrosses had 15% to 64% more resistant ears (less than 1% kernel damage at the tip only) than Jubilee. The inbreds and their commercial hybrid did not differ in resistance from Jubilee. Resistance to ECB appears to be polygenic and it has been suggested that some level of non-additive gene action is important. While the specific traits responsible for ear resistance are not known, the resistance of the breeding lines was transmitted to the testcrosses.

Abstract:

Excellent table quality is an essential characteristic of commercial sweet corn (Zea mays) and commonly held paramount as a selection criterion. As a consequence, breeding for improved agronomic performance in sweet corn has been limited in comparison with United States dent corn breeding efforts. The narrowness of genetic diversity within modern sweet corn germplasm suggests potential exists for yield enhancement through new heterotic combinations and introgression of sources of improved agronomic performance. The objective of this study was to examine the results of incorporating nonsweet germplasm in the development of improved temperate sweet corn cultivars. Five inbreds derived from crosses between nonsweet germplasm and temperate supersweet (shrunken2, sh2) inbreds were crossed with three temperate sh2 testers to make 15 experimental hybrids. The hybrids were evaluated in four environments with three replications per environments. Experimental entry Wh04038V × Tester2 yielded 18.1 Mg·ha−1 in 2009 and 16.6 Mg·ha−1 in 2010, significantly out-yielding the top producing commercial control, ‘Overland’, in both years. An additional six entries derived from exotic-by-temperate crosses yielded significantly more than all commercial checks in 2009. Four specific experimental entries consistently exhibited superior resistance to root lodging, northern corn leaf blight (Exserohilum turcicum), and Maize dwarf mosaic virus (MDMV) compared with ‘Marvel’ and ‘Supersweet Jubilee Plus’. Ten of the 15 experimental entries exhibited similar quality for flavor relative to ‘Marvel’ and ‘Overland’, however ‘Supersweet Jubilee Plus’ outperformed all entries for both flavor and tenderness, suggesting that while incorporation of nonsweet germplasm in sweet corn breeding programs may provide valuable contributions for yield and agronomic performance, flavor and tenderness must be carefully regarded.

Abstract:

Abstract To assess the genetic potential of white corn for corn grits, 28 hybrids resulting from diallel crosses of eight parents, including parents and S1 generations, were evaluated. The combining abilities and levels of heterosis and inbreeding depression were estimated. The parents used were the main white maize hybrids of the Brazilian germplasm. The combinations HT 9332 x HT 392, IAC Nelore x HT 9332, IAC Nelore x HT 932, and IPR 119 x IAC Nelore are promising for reciprocal recurrent selection programs targeting higher grain yield. Hybrid IPR 127 was indicated as a source of industrial lines with favorable traits for dry-rolled corn production. Hybrid IAC Nelore had the lowest estimate of inbreeding depression and was recommended for the breeding of lines and participation in higher-yielding hybrids and composites.
