摘要 为了筛选出适宜鄂东南地区种植的再生稻品种,选择了5个当地种植较多的杂交中稻品种进行试验,分别为Y两优2号、深两优5814、C两优4418、广两优476和隆两优华占,考察了各品种的生育期、产量、再生力等指标。结果表明,深两优5814表现优于其他品种,适宜作再生稻品种种植;隆两优华占理论产量较高,但是生育期较长,可能对再生季稻产量有一定影响。 For selection ratoon rice in southeast Hubei province,Y Liangyou No.2,Shenliangyou 5814,C Liangyou 4418,Guangli⁃angyou 476 and Longliangyou Huazhan were chosen as materials.And the growing stage,yield and ratoon ability of these five varieties was investigated.The results showed that the performance of Shenliangyou 5814 was good than other varieties,and it was suitably planted as ratoon rice variety.The theoretical yield of Longliangyou Huazhan was high,but the growth stage was longer than other vari⁃eties and bad for yield of ratoon season.
