四川省青贮玉米品种稳定性分析

Stability Analysis of Silage Maize Varieties in Sichuan Province

为了全面评价四川省青贮玉米品种产量的稳定性、适应性和丰产性,采用Eberhart-Russell模型、Franics和Kannenberg模型、HSC法,对2022年四川省青贮玉米区域试验进行综合分析.结果表明:惠民380和海南800平均产量分别为1124.5 kg/667m^(2)、1083.8 kg/667m^(2),比对照(CK)增产12.7%、8.7%;变异系数C_(V03)=29.6%、C_(V07)=28.3%,与对照C_(V10)=28.8%相差不大,且散布点图中处于第Ⅱ象限;高稳系数C_(HSV03)=72.2、C_(HSV07)=70.7,高于CK的C_(HSV10)=64.8;反应参数b_(V03)=1.04,b_(V07)=1.00.接近于1,稳定性参数S^(2)di与试验误差差异不显著,说明惠民380和海南800是高产、稳产、适应性广的青贮玉米品种,适合在四川省推广应用.

In order to evaluate the stability,adaptability and yield of silage maize varieties comprehensively,the Eberhart-Russell model,the Franics and Kannenberg model,and the HSC model was used to analyze the different silage maize varieties in regional experiment of silage maize in Sichuan province in 2022.The results show that the average output of Huiming 380 and Hainan 800 is 1124.5 kg/667m^(2) and 1083.8 kg/667m^(2),which are higher than the output of CK by 12.7%and 8.7%.C_(V03) is 29.6%and C_(V07) is 28.3%,both of them are in the quadrant II of scatter plot,which is little different from the C_(V10)(28.8%)of CK.CHS_(V03) and CHS_(V07) are 72.2 and 70.7,which are higher than C_(HSV10)(64.8)of CK;b_(V03) and b_(V07) are 1.04 and 1.00 that are all close to 1.S^(2)di are not different from experimental error significantly.It has been proved that Huiming 380 and Hainan 800 are high-yield,stableyield,wide adaptability silage maize varieties,which are suitable for promotion and application in Sichuan province.
