两系法杂交稻的研制成功,不但使杂交稻的制种技术有了一个新突破,更重要的是它能很好地解决三系杂交稻难以解决的将早熟与高产和高产与优质结合在一起的难题,为实现杂交稻的优质、高产栽培找到了新途径。因此两系法杂交稻开发前景广阔。从湖南省目前试种的品种看,两系法杂交稻比三系法杂交稻一般增产10％～20％。据湖南省“两系办”4个示范样板、848公顷两系杂交稻的产量统计,平均每亩(1亩=667
The successful development of two-line hybrid rice has not only made a new breakthrough in the seed production technology of hybrid rice, but more importantly, it can well solve the problem that the combination of early maturity, high yield and high yield with high quality Together, the puzzle has found a new way for high-quality and high-yielding cultivation of hybrid rice. Therefore, two lines hybrid rice development prospects. According to the varieties tested in Hunan Province, the two-line hybrid rice yield increased by 10% -20% compared with the three-line hybrid rice. According to Hunan Province, “two lines” 4 model, 848 hectares of two-line hybrid rice production statistics, the average per mu (1 mu = 667
