Abstract:

The maintenance of plant germplasm and its genetic diversity is critical to preserving and making it available for food security, so this invaluable diversity is not permanently lost due to population growth and development, climate change, or changing needs from the growers and/or the marketplace. There are numerous genebanks worldwide that serve to preserve valuable plant germplasm for humankind’s future and to serve as a resource for research, breeding, and training.

Abstract:

Worldwide, there are cuurently more than 60 germplasm banks that contain tomato (Lycopersicon esculentum) collections ranging is size from a few dozen to several thousands of accessions. In the utilization of these genetic resources sampling from only one germplasm bank may result in limiting available genetic diversity, whereas sampling from several germplasm banks may result in unnecessary redundancy. The current lack of knowledge regarding the relative magnitudes of genetic diversity contained within different collections makes it difficult to develop a core collection that maximizes geneti

Abstract:

Abstract The person who samples for germplasm collections occupies a very narrow temporal interface between the genetic resources that history has left as our endowment, and the potential uses of those resources with which we endow the future. It is a narrow interface because the genetic resource is eroding rapidly, and because our future needs are large and unpredictable. Given the structural complexity of most plant populations and the many possible ways that they may be used in the future, it is obviously impossible to prescribe simple, optimal sampling schemes for all species. However, a s

Plant genetic resources (PGR) are crucial for crop improvement programs. The National Genebank (NGB) at ICAR-NBPGR is responsible for collecting, conserving, and facilitating the utilization of genetic diversity in crop plants. Plant germplasm forms the foundation for plant genetic improvement. Extensive germplasm collections have been amassed and stored, presenting the challenge of effectively harnessing and exploiting this valuable resource.

Abstract:

Agriculture today is characterized by a sharp reduction in the diversity of cultivated plant due to human and natural event. Plant breeding contributes to decrease of crop diversity through expansion of genetically homogeneous cultivars and promotion of few widely adapted varieties. The size of germplasm collections frequently restricts access to them and consequently, their use in plant breeding and research. Therefore management and use of germplasm collections could be enhanced if a limited number of genetically diverse accessions within the collection were selected as the core collection.

Abstract:

The primary mission of germplasm collections is to preserve genetic diversity, but germplasm is preserved so that it can be used. Historically, the standard practice is that all germplasm accessions should be maintained as collected, so that even self-pollinated accessions are maintained as heterogeneous seed lots. In theory, this seems like an ideal strategy for preserving genetic diversity, but in practice, it is simply not workable. Heterogeneous accessions are in constant risk of change and loss. It is possible to mitigate the risk factors, but they can only be lessened and not eliminated.

The Instituto Nacional de Investigaciones Agrarias (INIA) has initiated in 1990 a Fruit Germplasm Project. The diversity of climates in Spain has made recommendable to scatter the different basic collections in different places, taking as a starting point the collections already existing at the different regional research centers across Spain. The species included in the Project are: almond, apple, apricot, banana, cherimoya, cherry, grape, hazelnut, mango, olive, peach, pear, prune and walnut. Details on these collections, their curators and the locations will be presented on the poster.

Abstract:

The collection and conservation of chickpea and lentil germplasm has great importance due to their role as a staple food for millions of people. Nowadays, the largest chickpea collection, 41.2% of the total accessions, is held by ICRISAT, while the main lentil collection is stored by ICARDA. The main fraction of both collections is constituted by Indian landraces. In recent decades, several efforts have been made to integrate all genebanks into a global conservation system of plant genetic resources. The release of informatics platforms allowed the creation of virtual genebanks, which are powe

Abstract:

Genetic variation in cucumber accessions from China was assessed by examining variation at 21 polymorphic isozyme loci. Principal component analysis of allelic variation allowed for the depiction of two distinct groupings of Chinese accessions collected in 1994 and 1996 (67 accessions). Six isozyme loci (Gpi, Gr, Mdh-2, Mpi-2, Pep-gl, and Pep-la) were important in elucidating these major groups. These groupings were different from a single grouping of Chinese 146 accessions acquired before 1994. Allelic variation in Chinese accessions allowed for comparisons with other accessions in the U.S. N

Abstract:

This paper is a tribute to the legacy of Dr Clive Francis, who directly and indirectly collected >14 000 accessions across 60 genera of pasture, forage, and crop species and their wild relatives around the Mediterranean basin, Eastern Africa, and Central and South Asia from 1973 to 2005. This was achieved by a collaborative approach that built strong interactions between disparate organisations (ICARDA, VIR, CLIMA, and Australian genebanks) based on germplasm exchange, conservation and documentation, capacity building, and joint collection. These activities greatly strengthened Australian p

Abstract:

The number and status of germplasm collections associated with plant breeding and applied genetics programs at U.S. public sector institutions [i.e., at both state (SAES) and federal (USDA ARS) agricultural experiment stations] was assessed from a resource conservation perspective via a questionnaire sent to over 1300 people who have been involved with the use or conservation of crop genetic resources in research, preservation, administration, or advisory capacities. The latter so-called working collections typically emphasize use rather than conservation of germplasm, while in turn preservati

Abstract:

Evaluation of genetic diversity within germplasm collections and identification of trait-specific germplasm is a basic requirement for plant breeders. A total of 221 Indian pearl millet collections from the National Genebank were characterised and evaluated for 27 agro-morphological descriptors. Considerable variation was observed for all characters. Frequency distribution analysis showed predominance of cylindrical and compact spike, grey seeds, earliness (less than 40 days to spike emergence). Hierarchical clustering method was used for classifying 221 pearl millet accessions based on agrono

Abstract:

Abstract The usefulness of core collections of germplasm collections has been well established. The U.S. germplasm collection for peanuts was selectively reduced based on morphological characteristics to a mini core or “Core of the Core” collection composed of 112 of the 7432 accessions in the whole collection to make it more efficient for study. Of these samples, 108 were available from one location in the same year and were therefore exposed to one set of environmental conditions wherein genetic variability could also be examined. These samples were analyzed for total and individual amino ac

Abstract:

A report on the tropical forage germplasm collection conserved in the CIAT genebank is presented. Emphasis is firstly on the assembling of the collection during 1972‒1993 through about 70 major and minor collecting missions in tropical America, Africa and Southeast Asia. Along with introductions from existing collections, currently some 1,600 accessions of 134 grass species and 21,000 accessions of 637 legume species are being maintained. Secondly, information on the utilization of the collection, with emphasis on cultivar development based on selection of accessions from the CIAT collection,

Abstract:

To streamline germplasm preservation, enhance resource utilization, and improve breeding efficiency, a core germplasm bank was established using 24 phenotypic traits and DNP markers from 155 pepper resources across various regions. Selection of the optimal core germplasm was based on intra-group retention ratio, overall retention scale, and intra-group stepwise clustering retention. Evaluation of phenotypic trait data for the core germplasm utilized mean, variance, range, and coefficient of variation, with principal component analysis confirming the selection.
