2015~2019年通过对广西全区14个地级市75个县级行政区开展种质资源普查与征集工作,同时组织专业调查队对13个地级市的50个县(区、市)开展系统调查与抢救性收集,共征集和收集到蔬菜资源1836份,隶属于19科,51属,81种。结果表明,广西蔬菜种质资源主要分布在桂北和桂西地区,海拔100~300 m的资源占44.28%,来自汉族、壮族、瑶族、苗族、侗族和毛南族6个民族,其中来自少数民族的资源数量占56.97%。通过对各类蔬菜资源开展鉴定评价工作,鉴定评价出优异资源资源511份,瓜类和葱姜蒜类居多,优异特性主要体现在高品质和抗病虫方面。本研究为广西蔬菜资源的保护和新品种选育提供科学依据。

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.
