摘要： 为筛选出适宜长沙地区种植的再生稻品种,以16个近年来通过审定的杂交稻品种(组合)为材料,以Y两优911(CK)为对照,开展再生稻产量、全生育期等适应性试验,从株型、生育期、产量及产量构成和其他重要性状表现等指标进行科学评价。结果表明,参试品种周年产量排名前三位的品种是贡两优粤农丝苗、恒丰优粤农丝苗和扬泰优5009,667 m2平均产量为853.9~869.9 kg,比Y两优911(CK)增产7.49%~9.50%。表明贡两优粤农丝苗、恒丰优粤农丝苗和扬泰优5009综合性状优良,适宜在长沙地区推广种植。

Abstract:

In order to select suitable varieties of regenerated rice for planting in Changsha Region, 16 hybrid rice varieties (combinations) that have been approved in recent years were used as materials,and Y Liangyou 911 (CK) was used as the control to conduct adaptability experiments on regenerated rice yield, growth period, and other important traits. Scientific evaluation was conducted based on plant type, growth period, yield and yield composition, and other important performance indicators. The results showed that the top three varieties in terms of annual yield among the tested varieties were Gongliangyou Yue Nongsi Miao, Hengfeng You Yue Nongsi Miao, and Yangtaiyou 5009, with an average yield of 853.9-869.9 kg per 667 m2, which wais 7.49%-9.50% higher than Y Liangyou 911 (CK). Gongliangyou Yue Nongsi Miao, Hengfengyou Yue Nongsi Miao, and Yangtaiyou 5009 have excellent comprehensive characteristics, which are more suitable for promotion and planting in the Changsha Region.
