| 摘 要： | 1978年我所用栽野型组合(萍矮58×华野)F_2中的无花粉型不育株与反交组合(华野×萍矮58)F_4中的正常株杂交,后代出现典败型变异株。经13个世代观察,该不育材料的测交、回交、姊妹交(不育株×可育株)F_1分离出的不育株与可育株呈1∶1;可育株自交后代育性不分离;“不育株”幼穗分化期在高温下(白天平均温度30℃以上)有部分结实,

| Abstract: | A typical abortion type of male-sterile plant was found in the progenies of(Ping Ai58×Hua Ye)F_2×(Hua Ye×Ping Ai 58)F_4 in 1978.The progenies from testcrossesor backcrosses or sib-crosses between male sterile and fertile plant were always segregatedin a ratio of 1 male-sterile to 1 fertile.Howeve |
