【摘要】观察国际水稻研究所(IRRI)7个不育系及其配组的杂交稻表现,IR68888A、IR68902A不育系花粉不育度高,杂种结实率高,农艺性状较好,外观米质优;IR68888A/明恢68和IR68888A/明恢70组合综合性状好,产量接近汕优63,有进一步进行生产试验的价值.更多还原

【Abstract】 Seven rice CMSlines introduced from International Rice Research Institute, and their corresponding hybrids were planted and studied. The results indicated that IR68888A and IR68902A had a high pollen sterile degree and good rice apparent quality, and hybrids by them had a high seed setting percentage and good agronomic traits. Among these hybrids, IR68888A/Minghui 68 and IR68888A/Minghui 70 had good comprehensive traits, and their yields approached Shanyou 63. The two hybrids deserve to be applied in the production.更多还原
