一、研究目的、试验材料和方法研究目的在于把已应用于芸苔属蔬菜植物的自交不亲和系育种的经验应用于甘兰型油菜,以得到优势强的自交不亲和系杂种而用于油菜生产。1972年春,我们在甘兰型油莱育种试验区中套袋自交300株,只得到2株不结实的单株。当年秋抪后,次年继续套袋自交,结果很不理想,基本上恢复了自交亲和。这是因为1972年套袋自交植株主要来源于甘兰型老品种和品种间杂种,而这些原始材料本身是自交亲和的。 First, the purpose of the study, experimental materials and methods The purpose of the study is to apply the experience of self-incompatible lines that have been applied to Brassica vegetable plants to Brassica napus in order to obtain superior self-incompatibility hybrids For rapeseed production. In the spring of 1972, we bagged self-made 300 bagging plants in the sweetlan breeding trial area, and obtained only two uncompacted plants. After the autumn harvest, the following year continued bagging self-fertilization, the result is not ideal, basically restored self-compatibility. This is because the 1972 self-primed bagging plants mainly come from the old varieties and inter-species hybrids, and these raw materials themselves are self-compatible.
