Abstract
The seed protein contents of 179 accessions belonging to ten species of genus Fagopyrum were determined by means of the Kjeldahl method. The results indicated that there are significant differences of seed protein content among different accessions within the same species. The average protein content of F. esculentum is 12.94%, ranging from 8.81–18.71%, and the protein content of Sibano is the highest, up to 18.71%, Gantian 1 the lowest with 8.81%. The average protein content of tartary buckwheat is 12.17%, with the range from 7.82–18.94%, and the protein content of cultivated tartary buckwheat Qianku 2 is the highest (18.59%), and that of Ganku 1 (7.82%) the lowest. Moreover, there are significant differences of seed protein content among different buckwheat species and between the different buckwheat types (between common buckwheat and tartary buckwheat, between the diploid and the tetraploid, between the cultivated and the wild, and between the big-achene group and the small-achene group). The average seed protein content of F. giganteum is the highest in all tested species, up to 17.81% with the range of 13.91–21.27%, and that of F. callianthum the lowest, only 8.31%.
