玉米新品种冀玉5817丰产性和稳产性分析

Analysis on the High and Stable Yield of New Maize Variety Jiyu5817

[目的]对冀玉5817的丰产性和稳产性进行分析,为进一步推广该玉米新品种提供科学依据。[方法]依据2011~2013年河北省夏播早熟组玉米区域试验、生产试验的产量结果,通过分析产量、产量变异系数、高稳系数、品种产量与环境指数的回归系数,对冀玉5817的丰产性和稳产性进行分析。[结果]冀玉5817在产量、产量变异系数、高稳系数等指标上均好于对照京单28。[结论]冀玉5817具有高产、稳产的特性,适合在河北唐山、廊坊市,保定北部和沧州北部,夏播玉米区大面积推广种植。

[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.
