摘  要：
介绍和分析了2005～2010年期间通过湖北省品种审定委员会审定的46个中稻的产量、米质、抗性等性状,其中两系杂交稻所占比重呈逐年上升的趋势,两系杂交稻比三系杂交稻的米质和产量略显优势。审定品种产量比对照平均增产3.56%,且呈逐年上升的趋势;米质达国标3级优质米以上的品种占76.9%;抗性鉴定结果表明,通过审定的品种对稻瘟病基本上均为高感,对白叶枯病大部分为感或高感。

摘  要：
The medium rice varieties(MRV)certified by Hubei Provincial Crop Variety Appraisal Committee from 2005 to 2010 were introduced and their traits such as yield,quality and resistance were analyzed.All of the 46 MRV were hybrid rice including three-line and two-line hybrid rice.The proportion of two-line varieties in MRV was increasing year by year and three-line varieties decreasing correspondingly.The yield and quality of two-line varieties were a little higher than three-line varieties.The yield of certified MRV was 3.56%higher than the check variety on average,and it was increasing year by year.About 76.9%of certified MRV met the 3rd class of national rice quality standards.Almost all varieties were highly susceptible to rice blast,and most varieties were susceptible or highly susceptible to bacterial blight.
