在毛主席革命路线指引下,几年来,我们开展了油菜雄性不育的研究工作,目前已获得一批有希望的“三系”材料,并初步进行了不育系繁殖杂交制种和杂种优势的利用,为进一步研究雄性不育、推广利用杂交种,积累了一些经验。在不育系选育方面,初步选获出四个较优不育系。其中不育株率80％以上的两个, In the past few years, under the guidance of Chairman Mao’s revolutionary line, we conducted a research work on male sterility of rapeseed. We have obtained a batch of promising “three lines” materials and initially carried out hybrid breeding and heterosis of sterile line breeding In order to further study male sterility and promote the use of hybrids, we have accumulated some experience. In sterile line selection, the initial selection of four better CMS. Which two sterile plant rate of 80% or more,
