Abstract | Objective: To evaluate the diversity of germplasm resources of Artemisia annua and provide the basis for improving utilization of germplasm resources, the agronomic traits of germplasm resources of A. annua were studied in Yun-Gui plateau. Method: The agronomic traits of 67 A. annua germplasm resources were measured by the visual observation and measurement methods. And the germplasm resources were clustered using flexible-beta method to analysis their genetic background. Result: The result showed that 67 germplasm resources had a relatively wide variation on the 22 agronomic traits. Among 22 agronomic traits, the dry weight of branch had the greatest coefficient of variation, which was 53. 63, and the next were the dry weight of leaf, total plant weight, the length of pinnules and the length of leaflet, which were 42.74, 41.61, 39.54 and 39.22 respectively. The smallest coefficient of variation was the leaf corlor. Based the result of cluster analysis, these 67 germplasm resources were classed into 5 groups, and each group had its respective character. The first group showed early-maturing resources, dwarf stalk, slender rod, long bipinnata, high leaf-stem ratio and moderate leaf weight The third group showed late-maturing resources, tall and thick stalk, much-branch, bushy accessory pinna, high leaf weight and yield. The fifth group showed very late-maturing resources, strong lateral shoot, high leaf yield. Conclusion: There were significant genetic difference and diversity in the germplasm resources of A. annua. The result of cluster analysis showed that the resources of group 1, group 3 and group 5 were suitable as breeding material of A. annua. |
