Genetic mapping of F2 progeny (n = 225) of hybrids between the Sobano variety of common buckwheat (Fagopyrum esculentum Moench) and the Homo wild accession (F. esculentum var. homotropicum) was carried out using randomly amplified polymorphic DNA (RAPD), sequence-tagged site (STS) and seed protein subunit markers, and three morphological traits. Ten linkage groups were identified, involving 87 RAPD markers, 12 STS markers, four seed protein subunit (PS62/PS59, PS49.8/PS51.4, PS44/PS42.9, and PS39.9/PS37.8) markers, and three morphological alleles controlling homo/long style (H/s), shattering habit (Sht/sht), and acute/obtuse achene ridge (Ac/ac), covering a total of 655.2 cM.
