The grain shape and quality traits of 26 Fagopyrum tataricum（L.） Gaertn seeds came from Bijie county of Guizhou provine were studied. The results showed that the variation ranges of grain length, grain width, grain thickness, bulk density, 1 000-grain weight, protein content, flavone content, soluble sugar content and water content were 4.10~5.71 mm, 2.81~3.54 mm, 2.71~3.26 mm, 565.54~ -686.84 g/L, 14.54~20.82 g, 6.12%~10.14%, 3.95%~10.60%, 4.15%~16.79% and 11.40%~13.67%, respectively. The average values were 4.62 mm, 3.22 mm, 2.97 mm, 627.46 g/L, 17.28 g, 7.84%, 6.20%, 9.95% and 12.71%, respectively. The correlation analysis showed that there was an extremely significant positive correlation between 1 000-grain weight and grain length, grain width as well as grain thickness. Whereas grain length was significant negative correlation with grain width, 1 000-grain weight and bulk density were positive correlation with grain width and grain thickness, grain length was negative correlation with grain thickness and bulk density. There was a positive correlation between protein content and flavone content as well as soluble sugar content, while protein content, flavone content and soluble sugar content was negative correlation with water content, and between soluble sugar content and water content reached an extremely significant level.
