近年来,人们对优质稻米越来越关切,但多数地方名贵品种植株较高,产量较低,直接用于生产有一定困难。如云南水稻品种资源丰富,其中名优品种很多,但在低海拔地区,则难于直接利用,也很难改造。为此,我们以云南水稻名贵品种作亲本进行杂交,研究杂种后代株高、穗数、米色等性状的遗传表现和利用途径,为我省育种提供材料和依据。

In recent years, people are increasingly concerned about the quality of rice. However, most local varieties have higher plantings, lower yields and direct application to production. Such as Yunnan rice varieties rich in resources, including many famous varieties, but at low altitude, it is difficult to direct use, it is difficult to transform. For this reason, we used the valuable rice varieties of Yunnan as parents to carry out crossbreeding, and studied the genetic expression and utilization of the characters of plant height, spike number and beige color of hybrid offspring, and provided the materials and basis for breeding in our province.
