Proceedings a/the 9th International Symposium on Buckwheat, Prague 2004 Characteristics of Genetic Resources in Tartary Buckwheat

This study carried out to investigate the main agricultural characters of Tartary buckwheat genetic resources that were collected in the world. 100 kernel weight of Tartary buckwheat ranged from 0.9g to 2.6g. 100 kernel weight of cultivated strains ranged from 1.0 to l.5g while that of wild strains ranged from 1.5 to 2.0g. The seed colors of 45 lines in Tartary buckwheat were divided to a brown, dark brown, dark gray, black. 100 kernel weight of dark brown seed color was higher than that of other colors. Fifteen strains were classified as Notched type, 7 strains was classified as Round type, and 23 strains was classified as Slender type in the seed shape of Tartary buckwheat. Flowering initiatio
