Abstract

Legumes are one of the most valuable gifts of nature to man, animal, and environment. These are sustainable, affordable, water-efficient, and low-carbon footprint crop. Globally, the share of grain legume accessions is 15% of 7.4 million accessions conserved in genebanks, of which more than half of germplasm in genebanks are without characterization and evaluation data which ultimately limit the utilization of germplasm in legume improvement programs. Characterization of all genebank accessions should be of utmost priority for enhancing the utilization. The development of core, mini-core, reference sets, and trait-specific germplasm has provided route to crop breeders for mining genebanks. Identification of new sources of variation became easy with these subsets, but the entire collection also needs to be evaluated for unique and rare traits. In crop species with narrow genetic base, utilization of crop wild relatives as well as new resources aids to widen the genetic base of legume cultigens.
豆科植物遗传资源:可持续发展的现状与机遇
豆科植物是大自然给人类、动物和环境最宝贵的礼物之一。这些都是可持续的、负担得起的、节水的、低碳足迹的作物。在全球范围内,在基因库保存的740万种质中,籽粒豆科种质所占的比例为15%,其中一半以上的种质没有鉴定和评估数据,这最终限制了种质在豆类改良计划中的利用。对所有的基因库材料进行鉴定是提高利用效率的首要任务。核心、小核心、参考集和性状特异性种质资源的开发为作物育种者挖掘基因库提供了途径。利用这些子集很容易识别新的变异来源,但还需要对整个集合进行独特和罕见性状的评估。在遗传基础较窄的作物品种中,利用作物野生近缘种和新资源有助于扩大豆科植物的遗传基础。
