全世界收集到的高粱种质资源168500份,其中国际热带半干旱地区作物研究所有36774份,占总数的21.8%,美国42221份,占25.1%,印度20812份,占12.4%,中国12836份,占7.6%,其他国家55857份,占33.1%。上述国际研究所和国家在对高粱种质资源进行收集、整理、登记的基础上,对其遗传的多样性和各种性状做了鉴定,从中筛选出许多具有优良农艺性状、品质性状、抗性性状的资源,满足了高粱遗传改良的需要,成为当代和未来人类有价值的资源。建立核心种质对种质资源的保存、维护和利用是一种经济、实用和有效的方法。
There are 168,500 sorghum germplasm collected worldwide, of which 36,774 are crop research in the International Tropical Semi-Arid Regions, accounting for 21.8% of the total, 42,221 or 25.1% in the United States, 20,812 or 12.4% in India, 12,836 in China, Accounting for 7.6%, 55857 other countries, accounting for 33.1%. Based on the collection, collation and registration of sorghum germplasm resources, the above international institutes and countries have identified their genetic diversity and various traits, and screened out many of them with excellent agronomic traits, quality traits, resistances Traits of resources to meet the needs of sorghum genetic improvement, become a valuable resource for the present and future mankind. Establishing a core collection of germplasm resources is an economical, practical and effective way to preserve, conserve and utilize germplasm resources.
