我国自50年代早籼矮化育种突破以来,我所也随之展开。20多年来我们以杂交育种法为主要手段,辅以理化途径。以丰、抗为主攻目标,相继选育出一批有生产价值的早籼良种:矮辐9号、早丰收、珍汕、珍龙13、军协、温选10号和温选青等。这些品种的推广应用,对提高水稻单产起了较大的作 Since the breakthrough of early indica dwarf breeding in China in the 1950s, our institute has also started to expand. For more than 20 years, we have adopted hybrid breeding as the main method, supplemented by physical and chemical means. In order to abundance, resistance as the main target, one after another bred a number of early indica varieties of production value: Dwarf 9, early harvest, Zhen Shan, Zhen Long 13, the military association, Wen Xuan 10 and Wen Xuanqing and so on. The promotion and application of these varieties have played a greater role in raising rice yield
