以湖南农业大学选育的12个早稻品系以及对照品种株两优819、陆两优996、中早35和中早39为材料,采用早季栽插、晚季直播的方式,进行了早晚两季品系比较试验,对参试品种的产量、生育期和主要产量性状进行了比较分析.结果表明:选育的新品系早品15早季全生育期与迟熟对照陆两优996相当,晚季全生育期与对照品种中早35一致,且其全年产量1 077.1 kg/667m2,较对照品种中早35增产7.0％,该品系有望作为新种质用于培育早晚兼用型水稻品种或者审定后应用于生产.

Taking new bred 12 rice lines and the control varieties（Zhuliangyou819, Luliangyou996, Zhongzao35and Zhongzao39） as materials, cultivar comparative trial was conductedby transplanted the rice in early season and direct seeded in later season. The yield, growth duration and main yield traits were investigated. The results showed that the new rice strain, Zaopin 15, which with the growth duration similar to the control variety of Luliangyou 996 in early season, has the growth duration equal to the control variety of Zhongzao 35 in late season. ...
