Abstract:
Taking 15 wild eggplant resources collected from different city of Yunnan Province as the test materials，investigation and stem，flower and fruit of 21 phenotypic traits and correlation analysis，principal component analysis and cluster analysis，the genetic diversity of eggplant was studied on the morphological level，the selected eggplant phenotypic richness and the genetic relationship among different germplasm were determined，more extensive and diverse excellent resources were obtained，in order to provide reference for the research of eggplant germplasm resources，breeding and selection of grafting rootstocks.The results showed that leaf length，leaf cleft，petiole length and plant height were positively correlated with each other by correlation analysis of 21 agronomic traits of eggplant.There was a significant positive correlation between strip color,edge,gloss,shape of fruit surface and leaf cleft，but a significant negative correlation between leaf cleft and commodity fruit color.There was a significant positive correlation between leaf length and fruit shape.Principal component analysis (PCA) extracted 21 traits into 4 main factors，with a cumulative contribution rate of 79.313%，which contained most information of all indicators.By calculating the comprehensive score，5 materials had excellent comprehensive performance (F>0.8).According to the genetic distance between germplasm，the 15 wild eggplant resources were divided into two groups.Group Ⅰ consisted of 11 materials.The commercial fruit color was bright and shiny，mainly yellow and orange-red,the fruit shape was round,oblate and oval.Group Ⅱ consists of 4 materials，tall plant type，thick leaf hypertrophy，deep or medium leaf cleft.
