Total 1072 accessions of local vegetables were collected in the field survey. The current study mainly focused on classification, distribution pattern, agronomic characters, conservation, main resources and special resources of vegetable germplasm. The main findings of the study were: (1) All resources of collected vegetable germplasm are belonged to 26 families; (2) Hong'an County, Zhongxiang City, Gucheng County, Nanzhang County andYuan'an County had more local vegetable cultivars than other counties (cities, districts); (3) Local cultivars showed high quality, high resistance and barren-tolerance, but most of them were distributed in remote areas with low purity, low yield and serious threat of degradation; (4) Most of the landraces were mainly preserved by some well-educated elder peasants; (5) The local cultivars of Cruciferae, Solanaceae, Cucurbitaceae, Liliaceae and Leguminosae accounted for 67.91% of the total vegetable resources; (6) Pearl flower (Staghylea Bumalda DC.), scallion (Allium paepalanthoides), elephant-foot yam (Amorphophallus spp.) and other important vegetable resources were scattered distributing in mountainous regions.
