摘　　要：分析了 1 5个常规晚粳稻品种主要经济性状的演变。结果表明 :“九五”以来我省选育的晚粳稻品种的产量明显提高 ,这主要归结于品种成穗数的增加和结实率的提高。对照部颁优质米标准 ,品质差异主要体现在垩白率、垩白度等外观品质上 ,绝大多数品种的食口性不尽人意。Development of major economic characters of 15 conventional late Japonica rice varieties was studied. The results indicated that yield of the late Japonica rice varieties in Jiangsu province had increased greatly since 1996. The increase of panicles and seed setting contribute to yield. As for the grain quality characters of late japonica rice, there existed great difference in physical properties such as chalky grain and chalky area.The taste of rice is disatisfied for people to most of those varieties. Breeding strategy about conventional late japonica rice at present in Jiangsu province was discussed as well.
