１９９３～１９９６年，测定了８０６份滇型杂交粳稻种质资源的抗瘟谱，筛选出抗谱较广的材料６４份。探讨了恢复系对杂种Ｆ１抗瘟性的贡献，提出了利用恢复系进行杂交粳稻抗病基因布局来控制稻瘟病发生的育种对策。
From 1993 to 1996, the anti-epidemic spectrum of 806 Dian-type japonica hybrid rice germplasm resources was determined, and 64 strains with wide spectrum of resistance were selected. The contribution of restorer lines to the blast resistance of hybrid F1 was discussed, and a breeding strategy was proposed to control the occurrence of rice blast by using the restorer lines for the resistance gene distribution in japonica hybrid rice.
