通过几年研究 ,发现了A3胞质雄性不育系小花不败育 ;培育出矮秆、穗大粒多、配合力强、育性又非常稳定的一批A3胞质雄性不育系 ;找到了难以恢复的A3不育系的恢复系 ,初配出了强优势杂交种 ;最后探讨了A3超强优势杂交种的选育途径
After several years of research, we found that the A3 cytoplasm male sterile line floret is unbeaten; cultivate a group of A3 cytoplasmic male sterile lines with dwarf, spike large grain, strong combining ability, fertility and very stable; found The restorer lines of the A3 sterile lines which were difficult to restore were initially provided with strong heterosis hybrids. Finally, the breeding methods of A3 superior heterosis hybrids were discussed
