摘要
对连续两年河南省绿豆多点试验的10个新品种农艺及产量性状进行变异性和相关性分析,探讨其相关关系;通过采用GGE双标图分析2019～2020年度河南省绿豆新品种鉴定试验参试品种,综合评价参试品种的丰产性、稳产性、适应性及各试点的试验代表性、鉴别力和区分能力.结果表明,株高、主茎分枝数、单株荚数的变异系数较大;单株荚数与主茎分枝、产量呈显著正相关,主茎节数与株高呈显著正相关.四个试点可以分为两个生态区,参试品种产量表现在双标图中能直观体现.安阳试点对品种有较强的鉴别能力,郑绿20具有较好的丰产性和稳产性,综合表现良好,具有推广价值.
Abstract
A correlation analysis was conducted on the agronomic and yield traits of ten new mung bean vari-eties tested in multiple sites in Henan Province for two consecutive years,and their correlation relationships were explored.GGE Biplot was used to analyze the tested varieties in the identification of new mung bean varieties in Henan Province from 2019 to 2020.The high yield,stable yield,adaptability of the tested varieties,representa-tiveness,discrimination,and differentiation ability of each pilot experiment were comprehensively evaluated.The results indicated that the variation coefficients of plant height,branch number of the main stem,and pod number per plant were higher.The pod number per plant was positively correlated with the branch number and yield of the main stems,and the node number of the main stems was positively correlated with plant height.The four pilot areas can be divided into two ecological zones,as effectively reflected in the Biplot.Pilot in Anyang has a strong identification ability for varieties,and the'Zhenglü 20'has good yield and stability,with good overall perform-ance and extension value.
