十字花科植物利用自交不亲和性是产生杂种的一个重要途径。50年代以来,国内外主要在白菜和甘兰蔬菜作物上,利用这种方法配制杂种,取得了很好效果。70年代在油菜上也有了成效,如华中农学院1972年开始研究自交不亲和性在甘兰油菜上的应用,1977年试种杂种,效果较好。我们从1976年开始选育自交不亲和系。通过几年工作,已有初步结果,报告如下。试验材料和方法自交不亲和系材料选自本所1971～75年杂交的甘×白后代,以后选出自交不亲和株,进行定向选育。对各系和杂种均进行人工辅助授粉自交、兄妹交。不亲和系每系测5—10
Cruciferal plants using self-incompatibility is an important way to produce hybrids. Since the 1950s, mainly at home and abroad in cabbage and cabbage vegetable crops, the use of this method to prepare hybrids, and achieved good results. In the seventies rape has also made some achievements. For example, Huazhong Agricultural College started to study the application of self-incompatibility in Brassica napus in 1972, and it was better to test the hybrid in 1977. We have been breeding self-incompatible lines since 1976. After several years of work, there are preliminary results, the report is as follows. MATERIALS AND METHODS Materials The self-incompatible materials were selected from Gan × white progenies crossed between 1971 and 75, and self-incompatible strains were selected for targeted breeding. All lines and hybrids were assisted by artificial pollination, brother and sister. Inconsistency measured 5-10 per line
