摘　　要：对2004～2008年长江中下游水稻早籼早中熟组可以申报国家审定的参试品种的试验结果进行了产量及其构成、抗性和米质的初步分析。结果显示,这类品种产量持续增长的主要原因是依赖穗粒数的增加,穗数与粒重在本分析中对产量增加的贡献不大;抗病性有减弱的迹象;米质的优质率低。揭示了早籼早中熟新品种的育种动态。According to 2004-2008 regional test results of rice varieties with early-mid maturity,which could declare National approve,in the Middle and Lower Reaches of the Yangtze River,a preliminary analysis was carried out on the yield and its components,resistance and grain quality.Results showed that sustainable growth of yield of these varieties mainly depended on the increase of grain number per spike.Spike number and 1000-kernel weight contributed little to the increase of yield.Disease resistance was weakened in these varieties.Grain quality was not so good.
