摘　　要：为筛选适用于“稻—再—油”种植模式的水稻品种,以仁优6号、针枣优939和济优1127等13个水稻品种为材料(陵两优268为对照),在湖南长沙(研究区A)、益阳(研究区B)开展“稻—再—油”模式下再生稻品种筛选试验,测定生育期、产量及产量构成等指标。结果表明,除盛两优358外,其余品种在研究区种植的生育期适宜,均能安全齐穗;在研究区A,仁优6号、荃早优1606周年产量分别为14.00和14.27 t/hm^(2),较对照增产5.34%和7.37%;在研究区B,仁优6号、陵两优741和荃早优1606周年产量分别为10.58、10.56和10.76 t/hm^(2),较对照增加7.65%~9.68%。上述品种均在10月中旬前成熟,能安全衔接油菜茬口。综合来看,湖南长沙地区以仁优6号、荃早优1606表现较好,湖南益阳地区以仁优6号、陵两优741和荃早优1606表现较好,适合作“稻—再—油”种植模式中的再生稻品种种植,各地区可根据当地种植实际进行选择。To screen rice varieties suitable for the“rice-ratooning rice-rapeseed”planting model,13 rice varieties including Renyou 6,Zhenzaoyou 939,and Jiyou 1127,etc.were used as materials (with Lingliangyou 268 as the control),and a selection experiment of regenerated rice varieties under the“rice-ratooning rice-rapeseed”model was conducted in Changsha (research area A) and Yiyang (research area B),Hunan Province,determine indicators such as reproductive period,yield,and yield composition.The results showed that,except for Shengliangyou 358,all other varieties had suitable growth periods for planting in the study area and could safely achieve full panicle.In research area A,the annual yields of Renyou 6 and Quanzaoyou 1606 were 14.00 and 14.27 t/hm^(2),respectively,which increased by5.34%and 7.37%compared to the control.In research area B,the annual yields of Renyou 6,Lingliangyou 741,and Quanzaoyou 1606 were 10.58,10.56,and 10.76 t/hm^(2),respectively,an increase of 7.65% to 9.68% compared to the control.The above varieties all mature before mid October and can safely transition the rapeseed crop.Overall,Renyou 6 and Quanzaoyou 1606 performed well in Changsha,Hunan Province,while Renyou 6,Lingliangyou 741,and Quanzaoyou 1606 performed well in Yiyang,Hunan Province.They are suitable for planting regenerated rice varieties in the cooperative“rice-ratooning rice-rapeseed”planting model,and can be selected according to local planting conditions in each region.
