以吉林省花生区域试验参试的11个花生品种为材料,对13个主要农艺性状进行变异系数、相关性和主成分分析。结果表明:单株结果数、侧枝长度和主茎高度的变异系数较大,分别为15.81%、13.21%和12.20%,生育期的变异系数最小为0.57%;在相关性上,小区产量与总分枝数、百果重呈显著正相关,生育期、单株结果数、单株饱果数和单株生产力也与小区产量呈正相关;主成分分析结果表明,前4个主成分对变异的累计贡献率达86.28%。在性状选择上,首先对变异大的性状进行选择是非常重要的,在品种选择上,应注意选择产量和总分枝数、百果重、单株结果数、单株生产力均高的品种。
The 11 peanut varieties tested in peanut regional trials in Jilin Province were used as materials to analyze the variation coefficient, correlation and principal component analysis of 13 major agronomic traits. The results showed that the coefficient of variation (CV) of single fruit number, collateral length and main stem height were 15.81%, 13.21% and 12.20% respectively, and the minimum coefficient of variation during growth was 0.57%. In the correlation, Branch number and fruit weight were significantly positive correlation, the growth period, the number of single plant, the number of fruit per plant and single plant productivity was also positively correlated with the yield of the community; principal component analysis showed that the first four principal components of the variation The cumulative contribution rate of 86.28%. In trait selection, it is very important to choose the trait with large variation firstly. In the selection of breeds, we should pay attention to the selection of varieties with high yield, total number of branches, fruit weight, fruit number per plant and high productivity per plant.
