野生稻有利基因的发掘和利用

Discovery and utilization of favorable genes in wild rice

野生稻作为栽培稻的野生亲缘种,具有许多优良的性状和有利基因,是栽培稻品种进一步改良的天然遗传种质资源库。其中,野生稻对病虫害的抗性、对各种逆境的耐受性以及胞质雄性不育等,已广泛应用于现代栽培稻的育种改良。文章综述了野生稻种质资源的有利性状及相应控制基因的发掘,探讨了其在今后水稻育种中的应用潜力。

Wild rice is the closely related wild relatives of cultivated rice. Wild rice provides natural genetic germplasm resources for improving cultivated rice varieties as it possesses many desirable traits and favorable genes, many of which, such as resistance to diseases and insect pests, tolerance to different kinds of stresses and its cytoplasmic male sterility, have been widely used in cultivated rice breeding. In this paper, favorable traits of wild rice germplasm resources and the related genes were summarized, and their utilization potential in rice breeding were also discussed.
