摘要： The hard-shelled character of ordinary cultivated Tartary buckwheat has become a factor influencing its taste and nutritional efficacy. However, the local variety, Rice-Tartary, can dehull easily. The genetic mechanism regulating easily-shelled Fagopyrum tataricum is unknown. In this study, the F-2 generation segregating population was constructed by crossing Yunqiao No.1 (hard-shelled) and Rice-Tartary (easily-shelled) as parents, and the bulked segregant analysis sequencing (BSA-seq) strategy was used to initial mapping. The gene locus controlling the easily-shelled trait of Tartary buckwheat was preliminarily located in the 4.07 Mb region of the first chromosome. To further narrow the range, the Kompetitive allele-specific PCR primers based on the single nucleotide polymorphisms in the initial location range were designed and tested in 335 individual plants in the hybrid F-2 population. The candidate gene Ftes1 was located between Ft6,705,225 and Ft7,041,921, according to the genetic linkage map constructed based on typing data. Combined with the location of candidate genes, the RNA-Seq data, and qRT-PCR results, the results indicate that 3 genes, FtPinG0001427400.01, FtPinG0001428600.01, and FtPinG0002492200.01 may regulate the easily-shelled Tartary buckwheat. The results of this study provide vital candidate genes for the cloning and functional analysis of genes related to easily-shelled traits, as well as prominent molecular markers for breeding of new varieties of Tartary buckwheat.
