中国作物种质资源多样性

本文综述了中国作物种质资源的物种多样性和遗传多样性。按农艺学和用途可将中国作物分为8大类即粮食作物、经济作物、蔬菜作物、果树作物、饲用和绿肥作物、花卉作物、药用作物和林木作物。汇集了中国作物总计有840种（类），涉及栽培物种1251个和野生近缘植物物种3308个，它们隶属176个科和619个属，这充分说明中国作物种质资源物种多样性相当丰富。依据中国作物的类型或变种多和性状变异幅度大，阐明了中国作物种质资源遗传多样性十分丰富。为中国作物种质资源的收集、保护、高效利用、创新、分类和遗传研究奠定了坚实基础，为生物多样性保护提供了科学依据。

Diversity of Crop Germplasm Resources in China

In this paper, Species diversity and genetic diversity of crop germplasm resources in China were summarized. The 8 kinds: food crop, economic crop, vegetable crop, fruit crop, forage and manure crop, flower crop, medicine crop and forest crop in China, according to agronomy and use were differentiated. Totally 840 kinds of crops in China were gathered, including 1251 cultivated species and 3308 species of their relatives, they are subordinate to 176 families and 619 genera, the rich species diversity of crop germplasm resources in China were identified. Fairly rich of genetic diversity of crop germplasm resources in China, according to very much types or varieties and heavy variation range of character of crop in China were expounded. This paper would provide the base to collection, conservation, effectively use, creation, classification and genetic research of crop germplasm resources in China.
