摘要
本研究对67个花生品种的9个农艺性状进行统计分析,利用其变异系数(CV)对各个农艺性状进行分析评价,并分析各农艺性状之间的相关性。结果表明,单株分枝数和单株产量的变异系数较大,而出仁率和饱果率的变异系数相对较小。单株产量与单株经济系数、百果重和百仁重呈极显著正相关,与单株分枝数呈显著相关;单株经济系数与百仁重、出仁率呈极显著正相关,与百果重呈显著正相关,而与叶面积呈显著负相关。用隶属函数度综合值进行聚类分析发现,67个花生品种在欧氏距离为5时可分为4个分支。
In this study, nine agronomic characters of 67 peanut cultivars were statistically analyzed, and the coefficients of variation(CV) were used to analyze and evaluate the agronomic characters and the correlationship. The results showed that the CV of branch number and yield per plant were larger, while the CV of kernel percent and full fruit rate were relatively smaller. The yield per plant was very significantly positively correlated with the economic coefficient per plant, hundred-pod weight and hundred-kernel weight, and significantly correlated with the branch number of single plant. The economic coefficient per plant was very significantly positively correlated with hundred-kernel weight and kernel ratio, and significantly positively correlated with hundred-pod weight, but significantly negatively correlated with leaf area. According to the cluster analysis with the comprehensive value of the degree of membership function, the 67 peanut varieties were divided into 4 categories at the Euclidean distance of 5.
