在汕优6号制种中,由于母本结实率低,具有较强的再生能力;同时,母本在灌浆时出现分蘖高峰,为再生多次制种提供了可能;另外,从母本再生力强的特点,调节父本生育特性,促使再生。基于上述分析,我们于1979—1982年,连续进行了试验,已初获成功。一次种植,三次收获,亩产达427斤。再生稻多次制种,适应当前农村生产责任制的需要,可以自由安排,不需严格的保
In Shanyou 6, the seed set had strong regeneration ability due to low seed setting rate. At the same time, the tillering peak appeared during the filling of the female parent, which provided the possibility of multiple seed production. In addition, Powerful features, regulating the characteristics of the parental reproduction, promote regeneration. Based on the above analysis, we conducted a series of experiments in succession from 1979 to 1982 and have achieved initial success. Once planted, three harvests, up to 427 kg per mu. Ratoon rice multiple seed production, to adapt to the current needs of rural production responsibility system, are free to arrange, without strict security
