【摘要】 对玉米胞质雄性不育系的多种利用方式进行了增产因素的分析比较,结果表明:自交系、制种试验中不育系的处理都有一定的增产作用;恢复型不育单交种和雄性不育化单交种的增产机理一致,都是通过降低穗长的变异系数,提高果穗的整齐度对产量产生影响。雄性不育与人工去雄的作用基本一致,都能对制种和大田生产起到增产的效果。更多还原

【Abstract】 The application method of cytoplasmic male sterile line was researched.The result showed that the treatment to inbred line and male sterile line in seeds production had the effect on yield-increasing and the mechanism of the yielding-increasing in restorer-sterile single-hybrids and sterility male-sterile single-hybrids was same.So,both the male sterile and artificial emasculation can improve yield.更多还原
