Abstract
[Objective] The high yield and stable yield of Jiyu5817 was analyzed,which will provide scientific basis for further extending this maize new variety.[Method] According to the yield results of the maize regional experiment in summer and early maturity group in Hebei Province during 2011-2013,through yield analysis,yield variation coefficient,high and stable coefficient of variety yield and environment index,the high yield and stable yield of Jiyu5817 was analyzed.[Result] The yield,yield variation coefficient,high and stable coefficient,regression coefficient of Jiyu5817 was better than that of Jingdan 28.[Conclusion] Jiyu5817 is a new maize variety with high yield and good stability,which is suitable for large scale planting in Tangshan,Langfang,northern Baoding,northern Cangzhou,summer maize sowing area.
