| 摘 要： | 应用随机多交加混合选择的方法，不仅可以改良单个性状柱头外露率，而且可以改良配合力、品质、抗性等综合性状。从用N8S、怀早4号、香2B和早优1号构建的两次随机多交加混合选择的群体中选育出一个柱头外露率高、配合力、品质和抗性都较对照V20A有明显改善的实用温敏核不育系准S。准S柱头外露率达78.6%，比对照V20A高72.4%。

| Abstract: | TGMS line is the key for breeding two-line system hybrid rice. Population improvement, or random polycross plus mass selection was adopted in this study, using N8S, Huaizao 4, Xiang 2B and Zaoyou1 as parents. It was concluded that population improvement could help comprehensively improve the importa |
