吉林省22份主推玉米品种区域试验评价

Evaluation of 22 Main Popularized Varieties by Variety Regional Trails in Jilin Province

采用线性模型+稳定性参数的分析方法,对2015-2017年吉林扶余、榆树、公主岭3个试验点的22个主推玉米品种进行区域试验统计。研究表明:除地点间和地点×品种效应未达到显著或极显著水平,其他变异来源均达到显著或极显著水平。3年3个地点品种平均产量变幅为8 673.9～10 324.6kg/hm^2,品种间子粒平均含水量变幅为19.3%～26.6%。3个地点平均产量由高到低依次为公主岭、榆树、扶余。3个地点平均产量由高到低依次为2017、2016、2015年。地点×品种互作效应由高到低依次为榆树、公主岭、扶余,即某品种在特定地点具有特殊的适应性。对3年3个地点22个品种的丰产性、稳定性参数进行分析,结果显示恒育218、吉单50、吉第816、优迪919、迪卡159、禾育89、金园15、农华101和先玉335的表现较优。结合产量-含水量关联分析评定,品种吉第816、先玉335、迪卡159、金园15、天农9和优迪919较优。

Data of twenty-two main maize varieties in Fuyu, Yushu and Gongzhuling between 2015-2017 were analyzed using the linear model and stability parameter analysis method. The study shows that the locations and varieties×locations did not reach a significant or extremely significant level. Other variations reached a significant or very significant level. The average yield amplitude of varieties was 8 673.9-10 324.6 kg/ha and the moisture content amplitude of varieties was 19.3%-26.6%. The average yield of 3 locations from high to low was Gongzhuling, Fuyu and Yushu. The average yield of 3 locations from high to low were 2017, 2016 and 2015. The interaction effects of varieties×locations from high to low were Yushu, Gongzhuling and Fuyu. That is, some varieties were adapted to specific environment condition. We analyzed 22 varieties by high yield and stability parameters of 3 locations in 3 years, the varieties of Hengyu 218, Jidan 50, Jidi 816, Youdi 919, Dika 159, Heyu 89, Jinyuan 15, Nonghua 101, Xianyu 335 were excellent in this study. The Correlation analysis of yield and water content showed that Jidi 816, Xianyu 335, Dika 159, Jinyuan 15, Tiannong 9, Youdi 919 were superior.
