为探讨利用大白菜雄性不育系生产一代杂种种子的可能性,我组于1972年开展了大白菜雄性不育系的选育工作。前一段着重研究了几份来源于小青口127号不育单株的雄性不育系(72049,72053)的遗传特点,以及利用它们生产一代杂种种子的可能性。初步
In order to explore the possibility of using Chinese male sterile lines to produce the first-generation hybrid seeds, our team carried out the breeding of male-sterile male-sterile Chinese cabbage in 1972. The previous section focused on the genetic characteristics of several male sterile lines (72049, 7203) derived from Xiaoqingkou 127 sterile plants and the possibility of using them to produce the first generation of hybrid seeds. preliminary
