水稻杂种优势利用的研究工作,近几年来取得了可喜成果,为适应长江流域种植双季稻的需要,急需解决早稻的三系配套。几年来,武汉大学遗传研究室利用红芒野生稻和秈稻品种进行杂交和连续回交,培育出了稳定的雄性不育系,实现了早稻的三系配套。经湖北省协作组初步鉴定证明杂种早熟、丰产、抗逆性强。 Research work on the utilization of heterosis in rice has made gratifying achievements in recent years. To meet the need of planting double cropping rice in the Yangtze River Basin, it is urgent to solve the three-line matching of early rice. Over the past few years, the genetic research laboratory of Wuhan University made use of the hybrids of Hongmang wild and indica varieties and continuous backcrossing to cultivate a stable male sterile line and achieve the three-line matching of early rice. Preliminary identification by the collaboration team in Hubei Province proved early hybrids, high yield, strong resistance.
