水稻超高产育种途径及问题探讨

Discussion on the Ways and Problems of Rice Super-yield Breeding

回顾了国内外水稻超高产育种背景与概况,认为种质资源的收集与创新、籼粳亚种间杂交及理想株型的塑造是水稻超高产育种的主要途径。对高产优质结合的方法、亲本材料的利用、加强组合选配及提高选择水平进行了探讨。

Looked back at the background and general situation of rice super-yield breeding,drew the conclusion that the main ways for rice super-yield breeding are searching and renewing germplasm resources,cross-breeding between the subspecies of indica rice and japonica rice and shaping the ideal rice.Had a discussion on the ways to connect high yield with good quality,utilization of parents,combination and assortative mating,and improve the selective level.
