【 摘 要 】

The leaf phenotypic characters of wild Pyracantha fortunaeana germplasm resources were investigated, from Sichuan and Yunnan Province in southwest China. The results indicated that there were abundant diversity in leaf length, leaf width, leaf index, petiole length and leaf area. The leaf phenotypic characters of Pyracantha fortunaeana germplasm resources from different source were significant different. The average coefficient of variation on leaf length, leaf width, leaf index, petiole length and leaf area of the four wild populations were more than 20%, where the average variation coefficient being the largest (48.62%), and the average coefficient of variation in leaf index was the smallest (22.60%). Among the populations, the average coefficient on variation of SCYA population was the biggest (45.97%), and the average coefficient of variation of YNZT population was the lowest (25.53%). Correlation analysis among phenotypic traits showed that there were significant or extremely significant positive correlations between the leaf traits of Pyracantha fortunaeana.
