用灰色关联分析法评价沈阳绿豆新品种联合鉴定试验

Joint Identification Test on Shenyang New Mung Bean Variety with Grey Correlation Analysis

[目的]为沈阳地区绿豆育种提供理论依据,并筛选适宜该地区种植的绿豆品种。[方法]运用灰色关联度分析法,对2011—2012年19个供试绿豆新品种进行联合鉴定试验,并对8个主要性状进行综合评价。[结果]绿豆不同性状与产量的关联度大小为:单株荚数>株高>生育日数>主茎节数>荚长>主茎分枝>百粒重>荚粒数。[结论]在进行单株选择时,应尽量选择单株荚数多、株高矮、早熟的材料。

The aim was to provide theoretical basis for breeding mung bean field and screening the suitable variety in shenyang area. [Methods] The 8 main traits from 19 varieties of mung beans were evaluated by united identification test from 2011 to 2012 with grey relational analysis. [Results] The related degree of different traits and yield of Mung bean was the pods number per plant〉plant height〉growing days〉the node number of main stem〉pod length〉main stem branches〉100-seeds weight〉seeds per pod. [Conclusion] In the individual choice, pods per plant, plant height, more precocious materials should be chosen.
