【摘要】 我们于1994年发现了玉米光敏雄性不育材料CA507，经过初步研究，认为该玉米光敏感雄性不育材料在短日照条件下表现雄性不育，在长日照条件下表现雄性可育，育性转换的临界日照长度是14～15h。光敏雄性不育性状表现隐性遗传。更多还原

【Abstract】 The photoperiod-sensitive male sterility in maize was discovered by us. Depending on theprimary study, we found that the materials CA507 displayed male sterility at shortlight condition, displayedmal fenility at longlight condition. The sensitive lightlength may be 14~15 hours. The light sensitivemale sterlity is Perhaps controlled by several recessive genes.更多还原
