于2016年早、晚季在湖南省浏阳市永安镇开展大田试验,对湖南常用米粉稻品种陆两优996、中嘉早17和中早39的产量形成特点和辐射利用率进行比较。结果表明,早季陆两优996的产量比中嘉早17和中早39高35.34%~46.18%,差异显著;晚季各品种的产量差异未达显著水平。早季陆两优996的每穗粒数、千粒重、成熟期干物质量、收获指数比其他2个品种分别高14.77%~29.41%、6.11%~13.2

The field experiments were conducted in Yongan Town, Liuyang City, Hunan Province in early and late seasons in 2016. The yield formation and radiation use efficiency were compared among three commonly used flour rice varieties in Hunan Province： Luliangyou 996（LLY996）, Zhongjiazao 17（ZJZ17） and Zhongzao 39 （ZZ39）. The results indicated that the yield of LLY996 was 34.34%~46.18% higher than that of ZJZ17 and ZZ39 in early season, and the differences were significant; while the differences of the yields in late season were insignificant.
