| 摘 要： | 探讨了全球稻种资源的收集保存情况以及我国水稻国外引种利用现状，说明了稻种遗传资源的多样性对于丰富我国稻种资源宝库和增加遗传多样性意义重大，同时，指出了选育品种的大面积推广、种植，品种单一化和遗传脆弱性日趋严重，导致栽培稻品种的遗传基础越来越狭窄，提出应加强国外水稻资源的引入、评价和利用力度，拓宽品种遗传背景。

| Abstract: | The collection and conservation situations of the worldwide rice germplasm resources and their introduction and utilization status in China were discussed.The great significance of the genetic resources diversity of rice for enriching the rice resources bank and increasing the genetic diversity was explained.Meanwhile,it was pointed out that the great spreading and planting,simplification and genetic frangibility of the improved rice varieties resulted in the narrow genetic background.Some suggestions were ... |
