近30年江苏省迟熟中粳品种产量与品质分析
Analysis on Yield and Quality of the Late-maturity Medium japonica Rice Varieties Released in Jiangsu Province in the Last 30 Years
摘要
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 1 983,Wuyujing 3 with yield of over 580 kg/667m2 bred in 1 992,Wuyunjing 8 with yield of over 650 kg/667m2 bred in 1 999,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.关键词
