Abstract

plant genetic are the key biological resources having great potential to meet the challenges of food and nutritional security. ICAR-National Bureau of Plant Genetic Resources (NBPGR) has been working with a network of 10 regional stations located in different agro-climatic zones of India for the management of genetic resources. The linkages established with CGIAR centres, national crop-based institutes and state agricultural universities are the backbones of PGR utilization. NBPGR characterizes and evaluates germplasm conserved in the Indian national genebank for different traits and provides material to breeders. The effective utilization of PGR in crop improvement programmes depends mainly on their systematic characterization and evaluation, and identification of potentially useful germplasm. To date, we have characterized more than 2.35 lakh accessions of different agri-horticultural crops and developed core collections for the effective management of a large number of accessions. Presently, our focus is on the large-scale characterization of entire germplasm conserved in the Indian National Genebank and detailed evaluation of prioritized crops; identification of reference sets and core sets for enhanced utilization.
印度国家基因库馆藏管理和利用的大规模表征
植物遗传资源是应对粮食和营养安全挑战的重要生物资源,具有巨大潜力。icar -国家植物遗传资源局(NBPGR)一直在与位于印度不同农业气候带的10个区域站组成的网络合作,管理遗传资源。与CGIAR中心、国家级作物研究所和国立农业大学建立的联系是转基因作物利用的支柱。NBPGR对印度国家基因库中保存的不同性状种质进行鉴定和评价,为育种者提供材料。PGR在作物改良计划中的有效利用主要取决于其系统的特性和评价,以及潜在有用种质的鉴定。迄今为止,我们已经鉴定了超过23.5万份不同的农业园艺作物材料,并开发了有效管理大量材料的核心收藏。目前,我们的重点是在印度国家基因库中保存的整个种质的大规模鉴定和优先作物的详细评估;识别参考集和核心集以提高利用率。
