Investigation of Germplasm Resources of Zanthoxylum bungeanum Maxim in the Eastern Agricultural Area of Qinghai Province
In order to investigate the Zanthoxylum bungeanum germplasm resources in Qinghai Province,this study took Zanthoxylum bungeanum in seven counties in the eastern agricultural area of Qinghai Province as the main research object.A total of 37 Zanthoxylum bungeanum germplasm resources in the eastern agricultural area of Qinghai Province were collected and a detailed plant investigation of phenotypic traits,including traits related to plant type,branches,leaves,and fruits.Survey data shows that the coefficient of variation of 19 phenotypic traits in 37 green pepper germplasm resources ranged from 7.26%to 59.82%,and the overall coefficient of variation averaged 18.17%.The indicator with the largest coefficient of variation was the number of fruits per ear,which was 59.82%.The coefficient of variation of skin extraction rate is the smallest,7.26%.The peeling rate of Zanthoxylum bungeanum shoots ranged from 13.43%to 21.94%,that of leaves ranged from 14.14%to 19.73%,and that of fruit phenotypic traits ranged from 7.26%to 59.82%.Based on the analysis of 19 phenotypic traits of 37 samples,it reflects to a certain extent the diversity of Zanthoxylum bungeanum germplasm resources in the eastern agricultural region of Qinghai Province,laying the foundation for in-depth research on its genetic diversity and its development and utilization in the future.
