摘要: 【目的】客观评价青贮玉米品种的丰产性、稳定性和适应性,为青贮玉米品种的推广提供参考。【方法】采用Shukla模型、Eberhart-Russell模型、AMMI模型以及RSD法,2022年于四川省宜宾市、乐山市、绵阳市等9个不同生态环境对9个青贮玉米品种(成单623、凉2020、成青3211、川单2110、乐1999、成单768、绵单968、南W3465、雅玉青贮8号)的生物干重进行综合分析。【结果】凉2020、成单623生物干重较高,分别为17 007.75 、16 664.55 kg/hm2,较雅玉青贮8号(CK)分别增产11.39%、9.14%;G×E互作Shukla方差较小,为5 332.98、2 520.75;RSD值较小,RSDG2=0.130 1、RSDG1=0.114 5;反应参数均小于1,bG1=0.919 1、bG2=0.951 9;稳定性参数S2di与试验误差差异不显著(P>0.05);稳定性参数Di值低,DG1=7.39、DG2=10.12。由各试验点环境指数可知,达州试验点最高,IE9=275.96;其次为南充点,IE4=253.76,对品种表现最为有利;巴中试验点鉴别力最强,DE5为17.74,雅安试验点鉴别力最弱,DE9为1.84。【结论】凉2020和成单623是高产、稳产、适应性广的青贮玉米品种,可推广应用。巴中试验点适合选择高产、稳产的青贮玉米品种;雅安试验点鉴别力较弱,不适于选择优质青贮玉米品种。

Abstract: 【Objective】To objectively evaluate the high yield,stability,and adaptability of silage maize varieties,and provide reference for the promotion of silage maize varieties.【Methods】Shukla model,Eberhart Russell model,AMMI model,and RSD method were used to comprehensively analyze the biological dry weight of 9 silage maize varieties(Chengdan 623,Liang 2020,Chengqing 3211,Chuandan 2110,Le1999,Chengdan 768,Miandan 968,NanW3465,Yayu silage No. 8) in 9 different ecological environments including Yibin City,Leshan City,and Mianyang City in Sichuan Province in 2022.【Results】Liang 2020 and Chengdan 623 had relatively high biological dry weight,with 17 007.75 and 16 664.55 kg/hm2,which were 11.39% and 9.14% increased compared to Yayu silage No. 8(CK). The Shukla variance of genotype and environment interaction(G×E) was small,with values of 5 332.98 and 2 520.75. The RSD value was small,RSDG2=0.130 1 and RSDG1=0.114 5. The reaction parameters were all less than 1,with bG1=0.919 1 and bG2=0.951 9. There was no significant difference(P>0.05) between the stability parameter S2di and the experimental error;the stability parameter Di value was low,with DG1=7.39 and DG2=10.12. From the environmental index of each test site,it could be seen that Dazhou test site had the highest with IE9=275.96,followed by Nanchong test site with IE4=253.76,which was the most favorable for variety performance. The maximum discriminant power DE5 of each test site was 17.74,and the minimum was 1.84,indicating that the Bazhong test site had the strongest discriminant power,while the Ya′an test site had the weakest discriminant power.【Conclusion】Liang 2020 and Chengdan 623 are high yield,stable,and widely adaptable silage maize varieties that can be widely promoted and applied.Bazhong test site is suitable for efficiently selecting high-yield and stable silage maize varieties,while Ya′an test site has weak discernment and is not suitable for efficiently selecting high-quality silage maize varieties.
