摘要
中国作物遗传资源异常丰富,全国编入作物遗传资源目录的已达35万份以上,这些资源具有丰富的多样性,主要表现在作物种类繁多,类型多样和野生近缘植物丰富.据统计,我国的主要作物种类有600多种,其中起源于本国的约300种.经过漫长的自然和人工选择,形成了多种多样的类型,如稻种资源有两个亚种,50个变种和962个变型,仅普通小麦的变种已达127个,居世界第3位.与此同时,还具有丰富多样的作物野生种质资源.
There are very abundant crop genetic resources in China, more than 350,000 accessions of crop genetic resources have already been catalogued all over the country. These resources have rich diversity which is characterized by the numrous kinds of crops, multi-types in each crop and abundant wild relative plants. According to statistics, there are more than 600 main crops used in China, among which about 300 crops originated in China. The natural and artificial selection of these crops has resulted in lots of different types. For example, there are 2 subspecies, 50 varieties and 962 forma of rice in China; Only common wheat in China has 127 varieties which reside the third position in the world. Moreover, there are abundant wild relatives of crop germplasm resources.
