Abstract
[Objective] To identify the adaptability,yielding ability and comprehensive resistance of new varieties of Indica hybrid rice,and to provide scientific basis for the dominant species extension in Jianghuai rice region.[Method] A total of 11 new varieties of indica hybrid rice were compared by variance analysis and least significant ranges (LSR-SSR).[Result] The whole growth stages of tested varieties were all within the suitable range.Compared with the control Ⅱ You 838,six varieties showed increase in yields,and four varieties decreased.All the varieties showed extremely significant differences with the control.[Conclusion] High-yield new varieties of Indica rice suitable for Jianghuai rice region and its surrounding areas are screened,which are Huiliangyou 348,Xinliangyou 223,Quanyou 822,Liangyou 383,Ⅱ You 024 and so on.
