| Abstract: | We have carried out the study of hybrid seed production of Yixiang1577 and its parents' characteristics. By the study of hybrid-seed-production and pureness-control techniques for hybrid rice Yixiang1577, we have made conclusions about how to arrange distance days between the dropping seeds of female parent and male parent, the usage of "920" for parents and the using time. As a result, we have had a suit of technique and measures for hybrid-seed-production and pureness -control techniques for hybrid rice Yixiang1577. |
