摘要
以籼型三系不育系宜香1A、Ⅱ-32A、冈46A和恢复系宜恢7633、宜恢7008、宜恢1525等为材料,研究了亲本和杂交后代的倒伏指数.结果表明,Ⅱ-32A的倒3节间抗倒能力极显著强于宜香1A;冈46A倒3节间的抗倒能力显著强于宜香1A;宜香1A和Ⅱ-32A所配品种倒3节间抗倒能力相当,都极显著优于冈46A所配品种倒3节间抗倒能力.母本及其所配品种的倒2节间和倒1节间倒伏指数无明显差异.
Using 3 CMS lines（ YixianglA, l1-32A and Gang46A） and 7 restorer lines（Yihui7633, Yihui7008, Yihui1525, etc. ） as the material,their resistant resistant index of third internodes to top of Yixiangl A was indexes were analysed. It was found that the significantly lower than that of Gang46A and II-32A. The resistant index of the crossing cultivars of Yixiangl A and II-32A was significantly higher than that of Gang46A. The resistant index in the second and first internodes to the top of male parents and their crossing cultivars had no significant differences.
