| 摘 要： | 用8个转抗真菌蛋白基因恢复系,与3个不育系按8×3不完全双列杂交配制24个组合,分析了转基因恢复系对其杂种F1主要农艺性状的影响。结果表明:转基因恢复系在10个研究性状中均对杂种F1存在极显著效应;转基因恢复系所配杂种F1优势普遍存在,但组合间和性状间有所变化,不同受体亲本的转基因恢复系对杂种F1的优势效应也存在一定差异;杂种F1的株高、剑叶长、剑叶宽、穗长、有效穗数及千粒重与转基因恢复系对应性状呈极显著或显著正相关,而穗实粒数和结实率与恢复系关系甚微,对转基因恢复系主要农艺性状的合理选择可提高其杂种F1的遗传选育效率。

| Abstract: | Eight restorer lines of hybrid rice,by which transferred with antifungal protein genes using biolistic bombardment,were chosen to estimate the effect of transgenic restorer lines on agronomic traits of F_1 hybrid rice by the way of incompleted diallel cross with three male-sterile lines.The result obtained showed that,all of agronomic traits of F_1 hybrid rice were obviously affected by transgenic restorer line.Heterosis of transgenic hybrid is widespread and various for different traits in a variety or different varieties in the same trait,they also revealed that heterosis is different fairly in transgenic hybrids whose originated from different non-transductive original cultivars.Coefficients of correlation in the same trait between transgenic restorer lines and F_1 hybrid rice,such as plant height,flag leaf length,flag leaf width,panicle length,number of panicles and 1000-grain weight were positively significant at 0.01 or at 0.05 level,indicated that selecting parents on main agronomic traits reasonably is very important to improving the efficiency of hybrid rice breeding. |
