1983年开始,利用中国高粱品种“黑壳歪脖张”经Co~(60)γ射线处理后选育出的恢复系72—513(吉农201)和西地迈罗高粱作亲本材料,采用核置换方法,进行人工去雄杂交和核置换获得雄性不育株,用南繁加速世代培育进程,育成了稳定的雄性不育体系,1988～1989年重复上述的杂交和核置换程序,获得同样的结果,这充分证明中国高梁72—513胞质是雄性不育胞质,具有重演性,定名为中国高粱胞质雄性不育系“吉农105”。 中国高粱72—513胞质雄性不育性的重演性鉴定和中国高粱胞质雄性不育系主要农艺性状见表1、表2。
Since 1983, the restorer lines 72-513 (Ji-nong 201) and the sorghum fescue (Merino sorghum sorghum L.) which were bred by the treatment of Co ~ (60) γ-ray were used as parent materials. Nuclear replacement method, artificial male sterility crosses and nuclear dislocation to obtain male sterile plants, with the South to speed up generations of breeding process, bred into a stable male sterile system, 1988 ~ 1989 repeat the above-mentioned hybridization and nuclear replacement procedures, access to the same This fully proves that the cytoplasm of sorghum 72-513 in China is a male sterility cytoplasm with reproducibility and is named as “China's sorghum cytoplasmic male sterile line” “Ji-nong 105”. Repetitive identification of Chinese sorghum 72-513 cytoplasmic male sterility and main agronomic traits of Chinese sorghum cytoplasmic male sterile line are shown in Table 1 and Table 2.
