通过对2010～2012年江苏省杂交晚粳和迟熟中粳3年区域试验结果的比较，分析了其主要农艺性状和品质性状。结果表明：与迟熟中粳相比，杂交晚粳组合表现为穗大粒多，增产优势明显，但结实率偏低；主要品质性状表现为整体水平低于常规品种，但具有一定的粒型优势，最后对江苏省杂交晚粳发展中存在的问题和发展方向进行了探讨。
通過對2010～2012年江囌省雜交晚粳和遲熟中粳3年區域試驗結果的比較，分析瞭其主要農藝性狀和品質性狀。結果錶明：與遲熟中粳相比，雜交晚粳組閤錶現為穗大粒多，增產優勢明顯，但結實率偏低；主要品質性狀錶現為整體水平低于常規品種，但具有一定的粒型優勢，最後對江囌省雜交晚粳髮展中存在的問題和髮展方嚮進行瞭探討。

According to the data of regional tests from 2010 to 2012 in Jiangsu province , the major agronomic and quality char-acters were compared between hybrid late japonica rice and conventional late -maturing middle japonica rice .The results showed that:in comparison with conventional late -maturing middle japonica rice , hybrid late japonica rice had larger spikes , more grains , higher yield , and relatively lower seed setting rate .The main quality characters ( except for grain shape ) of hybrid late japonica rice were generally lower than those of conventional late -maturing middle japonica rice .Finally, the author discussed the existent prob-lems and developmental direction of hybrid late japonica rice in Jiangsu province .
