Abstract:In order to clarify the distribution of quantitative traits of Angelica biserrata, fourteen quantitative traits of 6 A. biserrata germplasms were measured and analyzed. The results showed that there were significant differences of 8 quantitative traits among 6 resources, and 6 quantitative traits had not significant differences. The variation coefficient of 14 quantitative traits ranged from 6.47% to 33.34%, in which the largest was leaf area, and the smallest was the number of replicates of compound leaves. The distribution of 13 quantitative traits conform to the normal distribution except the number of replicates of compound leaves. There was significant positive correlation among leaf width, leaf length, leaf area and leaf circumference with correlation coefficients of 0.568-0.925, and those among other quantitative traits were all lower than 0.560. The principal component analysis showed that 10 quantitative traits played a major decisive role in more two principal components. Five quantitative traits, including multiple leaf circle number, leaf circumference, leaf area, leaf length and leaf order number were removed, the probability grading showed that eight quantitative traits were divided into 5 continuous distributions classification, 1 quantitative trait into 3 continuous distribution classifications.
