我们课题组实行教学、科研、生产三结合,于1972年开始研究甘兰型油菜杂种优势利用问题。我们的研究内容包括两个方面:一是雄性不育系的选育;二是自交不亲和系的选育。下面我们只就自交不亲和系的研究情况作简要介绍。什么叫自交不亲和系呢?就是选育一种虽然有正常雄蕊,而且能够散粉,但自交或系内兄妹交均不结实或结实极少的材料,即为自交不亲和系。以它为母本,用另一品种或品系作父本,间行种植,配制杂种,即为自交不亲和系杂种,或叫自交不育系杂种。 Our task force implementation of teaching, research, production of three combinations, in 1972 began to study the utilization of Brassica napus heterosis. Our research includes two aspects: one is the male sterile line selection and the other is the breeding of self-incompatible lines. Below we will only self-incompatibility research situation brief. What is self-incompatibility? It is to breed a Although there are normal stamens, but also to loose powder, but the self-or in-line brother and sister were not strong fruiting or sturdy material is self-incompatible . With it as the female parent, with another species or strain of male parent, inter-line planting, preparation of hybrids, is self-incompatible hybrids, or hybrids.
