杂种优势利用作为一种独立的育种途径在自花授粉作物中迅速推广,是得益于植物细胞质雄性不育性的发现和利用。因此,对作物细胞质的研究日益受到重视。我国杂交水稻自1973年“三系配套”以来,已育成的籼、粳、糯型多种水稻雄性不育系,按其不同细胞质来源已有60多种。近年来,我国 The use of heterosis as an independent breeding route in the self-pollination of crops is rapidly promoted, is due to the discovery and utilization of plant cytoplasmic male sterility. Therefore, the research of crop cytoplasm has been paid more and more attention. Since the hybrid rice system in China was established in 1973, more than 60 male sterile lines of indica, japonica and glutinous rice have been bred according to their different cytoplasm origins. In recent years, our country
