| Abstract: | The major characteristics of parents for two-line indica hybrid rice-Wandao 79 was revealed by 6-year's research and practice. On the basis of the parents' characteristics, the high-yield technique of fine quality seed production of two-line indica hybrid rice-Wandao 79 was considered to be:①Prediction and regulation of heading period;②Spray of Huaxinlin regulating flowering time of female parent X07S;③Establishment ideal female population structure to increase the rate of setting seed, and decrease the rate of shrunken grain and preharvest sprouting;④Harvest and seed-husking and sun-drying in time. |
