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/667m2、1083.8 kg/667m2,比对照(CK)增产 12.7%、8.7%;变异系数 CV03=29.6%、CV07=28.3%,与对照 CV10=28.8%相差不大,且散布点图中处于第Ⅱ象限;高稳系数CHSV03=72.2、CHSV07=70.7,高于CK的CHSV10=64.8;反应参数bV03=1.04,bV07=1.00.接近于1,稳定性参数S2di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.
Stability Analysis of Silage Maize Varieties in Sichuan Province
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/667m2 and 1083.8 kg/667m2,which are higher than the output of CK by 12.7%and 8.7%.CV03 is 29.6%and CV07 is 28.3%,both of them are in the quadrant Ⅱ of scatter plot,which is little different from the CV10(28.8%)of CK.CHSV03 and CHSV07 are 72.2 and 70.7,which are higher than CHSV10(64.8)of CK;bV03 and bV07 are 1.04 and 1.00 that are all close to 1.S2 di are not different from experimental error significantly.It has been proved that Huiming 380 and Hainan 800 are high-yield,stable-yield,wide adaptability silage maize varieties,which are suitable for promotion and application in Sichuan province.
