7个玉米杂交组合产量和抗性的多环境鉴定OA
Multi-Locational Assessment on Yield and Resistance of Seven Maize Hybrid Combinations
为选育适宜湖北西部山区生产的高产稳产型玉米新品种,将7个新组配玉米杂交组合(P1、P2、P3、P4、P5、P6、P7)在湖北省恩施州、十堰市、襄阳市、宜昌市遴选的7个试验地(E1、E2、E3、E4、E5、E6、E7)进行多环境鉴定,同时以华玉11为对照(CK),采用方差分析、AMMI模型、GGE双标图分析以及混合线性模型(LMM)对各参试玉米组合的丰产性、稳产性和育种值,以及各试验地对产量和抗病性的鉴别力进行分析.结果表明,组合P2产量最高,为10 294.50 kg/hm2,较CK增产8.78％,育种值为12.30,AMMI模型稳定值为1.016,GGE双标图稳定性排名第2位;组合P3产量排第2位,为9 956.40 kg/hm2,较CK增产5.19％,育种值为11.92,AMMI模型稳定值为0.215,GGE双标图稳定性排名第1位;组合P1、P6、P7产量与CK间无显著差异,组合P4、P5产量极显著低于CK.组合P2、P3、P4、P5、P6对大斑病、小斑病、南方锈病、灰斑病、白斑病、穗腐病、纹枯病、茎腐病等主流病害及倒伏均表现出良好的抗性.试验地E4、E3对产量的鉴别力最强,试验地E5对抗倒性的鉴别力最佳.综上,P2(YC002×EH125)、P3(YC002×N517)为高产、稳产组合,试验地湖北省恩施州利川市汪营镇秀水村、湖北省十堰市房县野人谷镇西蒿坪村、湖北省襄阳市南漳县板桥镇九龙观村为较佳试验点.
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.
