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.
