基于AMMI模型和GGE双标图对青稞区域试验进行综合评价
Comprehensive evaluation of regional trials for hulless barley based on AMMI model and GGE biplot
摘要
Abstract
This research aimed to accurately evaluate the productivity,stability,and adaptability of hulless barley(Hordeum vulgare var.nudum)varieties tested in Sichuan Province in 2023,as well as the discriminative power and representativeness of testing sites.Accordingly,the additive main effects and multiplicative interaction(AMMI)model written in the R language and genotype main effect plus genotype-environment interaction(GGE)biplots were employed to analyze the trial data and comprehensively evaluate 14 new hulless barley varieties(lines)and 5 testing sites.It was found that hulless barley yield was extremely significantly affected by the combined effects of genotype,environment and the interaction effect between the two;1277 and Aqing 6 were both high-yielding and stable-yielding varieties suitable for planting in Zoige County,Aba County and Songpan County.Lines 1325 and 10462 were high-yielding but stable-yielding varieties with general stability,which were ideal for growing in specific regions of Barkam City and Zamtang County.Among the five test sites,Aba County has strong representativeness and discrimination,making it an ideal test site for screening high-yielding and stable varieties,based on results in this study.The study provides technical data for the selection and formulation of planting recommendations for new hulless barley varieties on the Qinghai-Xizang Plateau and the selection of regional pilots.关键词
