    Abstract:

    From 2015 to 2019, through the general survey and collection of germplasm resources in 75 county-level administrative districts in 14 prefecture-level cities in Guangxi Zhuang Autonomous Region of China, and through organized systematic investigation and rescue collection in 50 counties (districts, cities) in 13 prefecture-level cities by our professional investigation teams, a total of 1836 vegetable resources belonging to 19 families, 51 genera and 81 species were solicited and collected. The results showed that the vegetable germplasm resources in Guangxi were mainly distributed in northern and western areas, among which 44.28% came from altitudes of 100-300 m and from the ethnic groups of Han, Zhuang, Yao, Miao, Dong and Maonan, of which again 56.97% came from ethnic minorities. Through the identification and evaluation of the various vegetable resources, 511 elite resources were selected, with cucurbits, alliums, and gingers in the majority. The excellent characteristics are mainly reflected in high quality and resistance to pests and diseases. This study provides scientific evidence for the conservation of vegetable resources and the breeding of new varieties in Guangxi.
