河南省玉米区试品种产量稳定性分析
Yield Stability Analysis for Maize Variety Regional Trial of henan Provice
【摘要】 用模型Yij=iμ+iβIj+iδj对2000年河南省玉米区试(套种组)品种在多个试点下产量的稳定性进行分析,分析结果表明:玉米区试品种间产量稳定性存在明显差异,其中属于高产稳产类的品种有:新单22、郑单518,高产不稳产品种有4个,低产稳产品种1个,低产不稳产品种有8个。
【Abstract】 The model,Yij=μi+βiIj+δij,defines the stability parame ters that may be used to describe the performance of the maize variety of regional trial of Henan over a series of environments.The results showed: the stability of yield for every variety existed significant difference.There were two high yield and stable varieties :Xindan 22,Zhengdan 518;four high yield and not stable varieties,one was tow yield and stable,eight low yield and not stable varieties.
