7个玉米杂交组合产量和抗性的多环境鉴定
Multi-Locational Assessment on Yield and Resistance of Seven Maize Hybrid Combinations
摘要
Abstract
To select high-yield and stable-yield new maize varieties suitable for maize production in the mountainous areas of western Hubei,in this study,seven newly-developed maize hybrid combinations(P1,P2,P3,P4,P5,P6,and P7)and the control variety Huayu 11(CK)were assessed across seven experimental sites(E1,E2,E3,E4,E5,E6,and E7)selected in Enshi,Shiyan,Xiangyang,and Yichang of Hubei province.Analysis of variance(ANOVA),the AMMI model,GGE biplot,and linear mixed model(LMM)were adopted to investigate the fertility,yield stability,and breeding value of each tested maize combination,as well as the discrimination ability of each experimental site for grain yield and disease resistance.The results showed that the combination P2 had the highest grain yield of 10 294.50 kg/ha,with a significant increase of 8.78％compared with CK,its breeding value was 12.30,the AMMI stability value was 1.016,and it ranked the second in stability based on the GGE biplot analysis.The combination P3 ranked the second in grain yield at 9 956.40 kg/ha,which was 5.19％higher than CK,with a breeding value of 11.92 and an AMMI stability value of 0.215,ranking first in stability in the GGE biplot.There was no significant difference in grain yield among P1,P6,P7 and CK,while the grain yields of P4 and P5 were extremely significantly lower than that of CK.The combinations of P2,P3,P4,P5 and P6 exhibited good resistance to major maize diseases including northern leaf blight,southern leaf blight,southern rust,gray leaf spot,white leaf spot,ear rot,sheath blight,and stalk rot,as well as excellent lodging resistance.The experimental site E4 and E3 possessed the strongest discrimination ability for grain yield,and E5 showed the optimal discrimination ability for lodging resistance.In conclusion,P2(YC002×EH125)and P3(YC002×N517)were high-yield and stable-yield combinations.The optimal trial sites were Xiushui village,Wangying town,Lichuan city,Enshi prefecture,Hubei province;Xihaoping village,Yeren Valley town,Fang county,Shiyan city,Hubei province;and Jiulongguan village,Banqiao town,Nanzhang county,Xiangyang city,Hubei province.关键词
