摘要: 通过对近30年来江苏省育成的45个迟熟中粳品种的区域试验资料分析和种植鉴定,了解江苏迟熟中粳品种的育种状况,为新品种选育提供参考依据。区试资料分析表明,江苏近30年来迟熟中粳品种产量连上3个台阶,代表品种为1983年审定的盐粳2号,产量达到500 kg/667m2;1992年审定的武育粳3号,产量达到580 kg/667m2;1999年审定的武运粳8号,产量达到650 kg/667m2。2005年以后育成的品种产量徘徊在600 kg/667m2。2012年扬州种植鉴定结果表明,不同时期育成的品种产量为500~600 kg/667m2,产量提升不明显。近年来注重品种的外观品质改良,垩白粒率有明显改进,但垩白度和食味品质的改良仍需要加强。

Abstract: In order to understand the breeding  situation and  trend of the latematurity medium  japonica  rice varieties in Jiangsu Province, the regional trial data and yield and quality of fortyfive latematurity medium japonica rice varieties released  in last thirty years were analyzed, which would provide a reference frame for the improvement and breeding of new varieties. The regional trial data showed that there were three development phases of yield of the latematurity medium japonica rice varieties and the representative varieties were Yanjing 2 with yield of over 500 kg/667m2 bred in 1983, Wuyujing 3 with yield of over 580 kg/667m2 bred in 1992, Wuyunjing 8 with yield of over 650 kg/667m2 bred in 1999, respectively. Yield of varieties bred after 2005 was fluctuated around 600 kg/667m2. Yield and quality of fortyfive latematurity medium  japonica rice varieties identified at Yangzhou in 2012 showed that  1) yield of varieties bred in different periods was all fluctuated from 500 kg/667m2 to 600 kg/667m2 and had not been developed significantly,  2) chalky grains of varieties had been improved significantly, but chalkiness and taste quality of varieties were still needed to be improved.
