为了探讨绿豆各主要农艺性状对产量影响的主次关系,以山西省农业科学院经济作物研究所新选育的15个绿豆品种为试验材料,运用灰色关联度分析方法,对与绿豆产量相关的7个主要农艺性状的关联度进行了评价分析。结果表明,绿豆产量与主要农艺性状的关联度由大到小排序为:主茎分枝数>单荚粒数>单株荚数>株高>荚长>百粒重>主茎节数。主茎分枝数与绿豆产量的关联度最大,r值为0.7142,其次是单荚粒数,r值为0.7028,荚长、百粒重和主茎节数影响相对较小。所以,在选育山西省绿豆新品种时,应注重主茎分枝数和单荚粒数多的品系选育。
In order to explore the primary and secondary relationships of the main agronomic traits on the yield of mung bean, 15 mungbean cultivars newly selected from the Institute of Economic Crops of Shanxi Academy of Agricultural Sciences were used as experimental materials. The gray relational grade The main agronomic traits associated with the degree of evaluation and analysis. The results showed that the correlation degree between mung bean yield and main agronomic traits was in descending order: main stem branch number> single pod grain number> pod number> plant height> pod length> 100-grain weight> main stem number. The correlation between the number of main stem branches and the yield of mung bean was the largest, with the r value of 0.7142, followed by the number of single pod grains with the r value of 0.7028. The effects of pod length, 100-grain weight and main stem number were relatively small. Therefore, breeding new varieties of mung bean in Shanxi Province, should pay attention to the main stem branch number and the number of pods and more lines breeding.
