| Abstract: | China is the largest pepper producer and consumer country in the world. Green skin pepper and yellow skin pepper are the main vegetable pepper varieties in the market. It is particularly important to understand the characteristics and differences in the phenotypic traits and genetic diversity of mainstream yellow skin pepper and green skin pepper varieties in the market. Therefore, we conducted a comparative analysis of the coefficient of variation, genetic diversity index, correlation, main component and clustering of 25 field phenotypic traits of 36 yellow skin peppers and 38 green skin peppers that are currently the mainstream in the market. The results showed that in addition to the difference in fruit color, there are also certain differences in traits such as plant height, single fruit weight, fruit surface texture and fruit surface shrinkage between yellow skin pepper and green skin pepper, the average plant height of yellow pepper is about 16% higher than that of green pepper, the average weight of a single fruit of yellow skin pepper is about 41.4% heavier than that of green skin pepper, the overall surface of the green pepper is weaker and the texture is smoother, while the yellow pepper is more wrinkled. In the genetic diversity index, the variation range of yellow skin pepper is 0.1268-0.9915, and that of green skin pepper is 0.2762-1.3697,and the diversity of green skin peppers is higher than that of yellow skin peppers. There are differences in the correlation between plant height and fruit shape index, plant height and fruit longitudinal diameter, and leaf length and fruit transverse diameter, single fruit weight and fruit shape index, and leaf width and fruit transverse diameter, single fruit weight and fruit shape index, and longitudinal diameter and transverse diameter in yellow skin pepper and green skin pepper. Fruit factor is a comprehensive index that dominates the characteristics of yellow skin pepper, and growth factor is a comprehensive index that affects the characteristics of green pepper. The results of cluster analysis were categorized by the traits with higher principal component loading values, and echoes the results of the principal component analysis, and contains similar yellow pepper and green pepper varieties, and contrasts with the separate clustering results. After cluster analysis, 36 yellow skin pepper varieties were divided into 7 groups, among which the first group had 19 varieties, accounting for 52.7% of all yellow skin pepper,38 green pepper varieties were divided into 7 groups, among which there were 9 varieties in the fifth group and the sixth group, accounting for 23.6% of the total, this shows that the homogeneity among pepper varieties is relatively serious. |
