通过对江苏省近１０年审定的１５个晚粳（糯）品种在省区域试验中主要农艺和经济性状资料的分析表明，我省常规晚粳品种由多穗向多穗大穗相结合的类型演变，每亩有效穗和每穗实粒数均有所增加，结实率进一步提高，千粒重有所下降。今后高产育种要通过不断发现和利用有利遗传资源，改良株型，在保持现有穗数和结实率的基础上，求大穗大粒，以提高粒重为突破口，进一步提高晚粳新品种的产量和质量。
Through the analysis of the data of major agronomic and economic traits of 15 late japonica (waxy) cultivars approved in Jiangsu Province in the recent 10 years, the results showed that the type of conventional late japonica rice cultivars in our province consisted of the combination of multiple panicles to multiple panicles and large panicles Evolved, the effective panicle per acre and grain number per panicle increased, the seed setting rate further increased, the grain weight decreased. In the future, high-yielding breeding should find large panicle and big grain on the basis of constantly finding and utilizing favorable genetic resources and improving plant type, in order to improve grain weight as a breakthrough and further improve the yield of new late japonica rice And quality.
