农作物抗病、优质、高产等性状主要是由基因控制的,基因存在于作物的种质资源之中。种质资源中优异基因的发掘可使农业生产取得突破性的进展,如我国杂交水稻的成功就是对野生水稻种质资源中不育基因的开发利用。我国是个农业大国,优异基因的利用尤其重要。我国占有丰富的基因资源,优异基因的发掘也有着广阔的发展前景。1998年启动的“国家重点基础研究发展规划”(即973项目)中,有一个项目就是“农作物核心种质构建、
The disease resistance, high quality, high yield and other traits of crops are mainly controlled by genes. Genes exist in the germplasm resources of crops. The discovery of excellent genes in germplasm resources can make a breakthrough in agricultural production. For example, the success of hybrid rice in China is the development and utilization of sterile genes in wild rice germplasm. Our country is a big agricultural country, and the utilization of excellent genes is especially important. Our country is rich in genetic resources, and the discovery of excellent genes also has broad prospects for development. One of the projects launched in 1998, ”National Key Basic Research Development Plan“ (ie, the 973 project) is ”the construction of core crop germplasm,
