鹰嘴豆是作为膳食蛋白质来源的第三大豆类作物。亚洲国家不断增长的需求要求培育上级desi型品种，这反过来又要求育种者能够获得具有特征的种质。位于新德里国家植物遗传资源局的印度国家基因库保存了14,651份鹰嘴豆。整个集合的特征在于在一个单一的大规模实验。8个数量和12个质量农业形态性状的高变异。等位基因丰富度程序组装一个核心集，包括1103加入，其中70.0%是印度的起源。前三个主成分解释的总变异值在整个集合（51.1%）和核心集合（52.4%）中具有可比性，并且核心集合中数量性状之间的9个成对r值保持不变，符合率约为99.7%，表明鹰嘴豆核心确实是国家基因库整个鹰嘴豆集合的优秀代表。鹰嘴豆核心表现出更大的多样性比整个收集农业形态性状，更高的方差和香农-韦弗多样性指数评估，表明鹰嘴豆核心最大限度地提高了印度鹰嘴豆种质的表型多样性。鹰嘴豆核心，主要包括土著德西基因型，预计将是一个很好的资源，鹰嘴豆育种。关于鹰嘴豆核心的信息可以在http://www.nbpgr.ernet.in/pgrportal上获得。(C)2016年中国农业科学院作物科学研究所、中国作物学会制作和托管由Elsevier B.

Chickpea is the third most important pulse crop as a source of dietary protein. Ever-increasing demand in Asian countries calls for breeding superior desi-type varieties, in turn necessitating the availability of characterized germplasm to breeders. The Indian National Genebank, located at the National Bureau of Plant Genetic Resources, New Delhi, conserves 14,651 accessions of chickpea. The entire set was characterized in a single large-scale experiment. High variation was observed for eight quantitative and 12 qualitative agro-morphological traits. Allelic richness procedure was employed to assemble a core set comprising 1103 accessions, 70.0% of which were of Indian origin. Comparable values of total variation explained by the first three principal components in the entire collection (51.1%) and the core (52.4%) together with conservation of nine pairwise r values among quantitative traits in the core collection and a coincidence rate around 99.7% indicated that the chickpea core was indeed an excellent representation of the entire chickpea collection in the National Genebank. The chickpea core exhibited greater diversity than the entire collection in agro-morphological traits, as assessed by higher variance and Shannon-Weaver diversity indices, indicating that the chickpea core maximized the phenotypic diversity available in the Indian chickpea germplasm. The chickpea core, comprising mainly indigenous desi genotypes, is expected to be an excellent resource for chickpea breeders.
