摘要
以杂交水稻组合Y两优9918为对照,对14个杂交水稻组合进行再生稻比较试验,主要从组合生育期、农艺性状、产量及产量构成因素、稻米品质、稻瘟病抗性等性状方面进行综合比较分析,对品种的适用性进行了初步评价。结果表明,深两优475、两优南晶香占、两优1619、恒两优南晶香占、两优2019、桂香优169具有再生力强、产量高、稻米品质优等特点,适合在长沙地区作再生稻种植,其中,深两优475表现最优,可作再生稻规模化推广应用。
Taking hybrid rice combination Y Liangyou 9918 as the control,a comparative experiment of ratoon rice was conducted on 14 hybrid rice combinations,mainly from the traits of growth period,agronomic traits,yield and yield components,grain quality and rice blast resistance to carry out comprehensive comparative analysis,and the applicability of the varieties was preliminarily evaluated.The results showed that Shenliangyou 475,Liangyou Nanjingxiangzhan,Liangyou 1619,Hengliangyou Nanjingxiangzhan,Liangyou 2019,and Guixiangyou 169 had the characteristics of strong ratooning ability,high yield and good grain quality,and were suitable for ratoon rice planting in Changsha area.Among them,Shenliangyou 475 performed the best and could be used as ratoon rice for large-scale promotion and application.
