基于AMMI模型和GGE双标图的'安玉707'丰产稳产性及适应性分析
Analysis of High-Yield,Stable Yield and Adaptability of'Anyu 707'based on AMMI Model and GGE Biplot
摘要
Abstract
With prominent advantages including high yield potential,stable productivity,strong lodging resistance,high planting den-sity tolerance and wide ecological adaptability,the new corn cultivar'Anyu 707'was investigated in this study to scientifically and ac-curately evaluate its yielding performance and yield stability as well as identify its optimum planting regions.Based on consecutive two-year field trial datasets collected from 2020 to 2021,the AMMI model and GGE biplot were adopted to analyze the average grain yield,high-yielding capacity,yield stability and suitable planting zones of'Anyu 707'.Analysis of variance via the AMMI model re-vealed extremely significant differences(P<0.01)among tested corn cultivars,trial locations,and cultivar-by-location interaction ef-fects,with environmental effect serving as the dominant factor affecting corn grain yield.Combined results from the AMMI model and GGE biplot indicated divergent annual performances:in the 2020 trial,'Anyu 707'exhibited steady average yields across all test sites and ranked first in yield stability among all entries,yet its mediocre average grain yield led to a low ranking in high-yielding perfor-mance.In contrast,the cultivar topped all tested varieties for average grain yield with superior yielding ability in the 2021 experiment,accompanied by consistent yield performance across locations and favourable yield stability.Synthesized two-year experimental data verify that'Anyu 707'possesses satisfactory overall yielding capacity and outstanding yield stability alongside robust environmental adaptability,making it appropriate for summer sowing cultivation in Henan Province.关键词
