基于AMMI模型的小麦品种丰产稳产适应性及品质分析

Analysis of High and Stable Yield Adaptability and Quality of Wheat Varieties Based on AMMI Model

为筛选高产优质小麦新品种,以2016—2018年参加河南省小麦产业技术创新战略联盟新品种试验联合体区域试验的9份小麦品种(系)为材料,对产量与品质指标进行AMMI分析与灰色关联度分析。结果表明:漯麦906在2016—2017和2017—2018年度的表现均较好。主要表现为:(1)丰产性好。2个年度的平均产量分别为8269.18和6562.61 kg/hm^(2),排名分别为第1和第2位。(2)D值较低,2个年度分别为14.16、15.80,均排名第3,且稳产性和适应性较好。(3)灰色综合评价值较高,加权差值较小,品质年际间稳定性好,其稳定时间为中筋以上水平,且综合性状表现较好。因此,漯麦906符合当前小麦高产、稳产、广适、优质并进的育种目标。

In order to screen new wheat varieties with high yield and high quality,nine wheat varieties(lines)from the regional trial of wheat industrial technological innovation strategic alliance in Henan Province from 2016 to 2018 were used as materials,and the yield and quality indexes were analyzed by AMMI analysis and grey correlation analysis.The results show that the performance of Luomai 906 was better in both 2016 to 2017 and 2017 to 2018 with following characteristics.(1)High yield.The average yield of two years was 8269.18 and 6562.61 kg/hm^(2),respectively,ranking first and second respectively.(2)D value was lower which was14.16 and 15.80 in two years,both ranked third,and the yield stability and adaptability were better.(3)The grey comprehensive evaluation value was higher,the weighted difference was small,the interannual stability of quality was good,the stable time was above medium gluten level,and the comprehensive character performance was better.Therefore,Luomai 906 accords with the current breeding goal of high yield,stable yield,wide adaptability and high quality of wheat.
