摘要

Genetic diversity analysis is very important for germplasm conservation and utilization. In this study, 13 quantitative traits of 50 Amomum tsao-ko plants were assessed by basic statistical parameters and principal component analysis (PCA). The results indicated that the phenotypic diversity was abundant in Amomum tsao-ko. Coefficients of variation (CV) ranged from 7.60% to 43.86%, and the largest of variation coefficient was the fruiting rate, while fresh fruit width was low. Shannon-Weaver diversity index (H') of 13 traits ranged from 1.71 to 2.22, the largest and the smallest H' values were observed in seed regiment weight and fresh fruit weight, respectively. The principal component analysis (PCA) explained 78.381% of the total variation in four components. The first principal component was determined by dry fruit weight, fresh fruit width, dry fruit peel weight and seed regiment weight. The second was determined by fresh fruit length, dry fruit length and ratio of dry fruit length and width. The third mainly represented number of seeds per fruit, and the fourth reflected fresh fruit weight. Increasing the first principal component factor will be favorable for increasing the fruit weight, while the second principal component of the change will affect the shape of fruit.
