Abstract:To clarify the distribution and population size of buckwheat germplasm resources in Sichuan, in 2022-2023, the Wild Buckwheat Resource Survey Team conducted a systematic survey and collection of resources in Sichuan. We conducted a survey and collection of wild buckwheat resources in Sichuan, the survey area is mainly for the northwest Sichuan Province, southwest Sichuan Province and the Sichuan Basin of the Chengdu Plain, Sichuan Hills, in 30 counties (districts) within the wild buckwheat survey and collection of work. We collected a total of 156 wild plant germplasm resources of the genus buckwheat (103 F. cymosum (Trevir.) Meisn., 23 F. tataricum subsp. potanini, 3 F. esculentum subsp. ancestrale, 17 F. gracilipes (Hemsl.) Dammer. ex Diels, 5 F. leptopodum (Diels) Hedberg, 2 F. caudatum (Sam.) A. J. Li, 2 F. macrocarpum Ohsako et Ohnishi, 1 F. rubifolium Ohsako et Ohnishi). Extensive genetic variation exists among wild buckwheat resources from different habitats.
