| 摘 要： | 以2000—2010年通过浙江省审定的常规晚粳(糯)稻品种为研究对象,对浙江省区试和生产试验的产量、生育期、农艺性状和抗性的发展变化规律进行分析,结果表明:浙江省近年审定的常规单季晚粳稻品种的有效穗数在减少和每穗实粒数增加较明显,双季晚粳稻品种的每穗实粒数增加较明显,产量逐渐提高。总体而言,浙江省近年育成的晚粳稻新品种有向大穗型发展的趋势,新品种对白叶枯病的抗性也有一定的增强。

| Abstract: | In regional trial and production test,the changes and developments of yield,growth period and other agronomic traits associated with rice resistance of the conventional photo-sensitive japonica(glutinous) varieties registered by Zhejiang Province during 2000-2010 were analyzed in this paper.The results indicated that the effective panicle number per plant decreased while the number of grains per panicle increased in single season photo-sensitive japonica varieties.The number of grains per panicle increased more obviously in double-season photo-sensitive japonica rice varieties and the yield gradually increased.Overall,the breeding trend of photo-sensitive japonica varieties was to the development of large panicle.The resistance to bacterial leaf blight also increased. |
