摘　　要：通过 6年制种实践和研究 ,探明了新组合皖稻 79双亲主要特性 ,提出早预测 ,重调整 ,保花期全遇 ;适时喷施花信灵 ,促母本花时提早 ;搭建健壮合理母本群体 ,提高结实率 ,降低张颖率和穗发芽率 ;以及及时收割、脱粒、晾晒 ,保证种子质量等高产高质量制种技术措施。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.
