[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 research aimed to analyze the yield and stability of Jiyu 5817 and provide a scientific basis for further popularizing the new corn variety. [Method] According to the yield results of maize experiment and production experiment of summer sowing early maturing group in Hebei Province from 2011 to 2013, by analyzing the regression coefficient of yield, yield coefficient of variation, high stable coefficient, variety yield and environmental index, High yield and stability of the analysis. [Result] Jiyu 5817 was better than control Jingdan 28 in the indexes of yield, yield coefficient of variation and high stability. [Conclusion] Jiyu 5817 had the features of high yield and stable yield, suitable for large area popularization planting in Tangshan, Langfang, Baoding and northern Cangzhou of Hebei Province.
