Fig. 1 Relative yield and seed maturation proportions for two buckwheat genotypes during the ripening season. Relative yields, represented as open or filled bars, were calculated as percentages compared with the maximum yields during the ripening period for each genotype. Discoloration proportions were represented as lines with triangles or squares. LSD (0.05) in relative yields were 4.5 for Kitawasesoba in 1997, 4.2 for Kitawase D in 1997, 2.6 for Kitawasesoba in 1998, and 3.2 for Kitawase D in 1998
