Abstract: 97 pea germplasm resources from Hubei，Henan，and abroad were collected as the research object，and the appearance and nutritional quality of dried pea seeds were observed and measured. The results showed that grain shapes were mainly spherical，cylindrical，and oblate，accounting for 31%，37%，and 32%，respectively. Grain colors of green，pale yellow，brown，yellow，and pink accounted for 34%，34%，30%，1%，and 1%，respectively. Pit，wrinkled and smooth seed surfaces accounted for 33%，41%，and 26%，respectively. Pea resource′s seeds with yellow umbilical color accounted for 57%，and resources seeds′ umbilical color was gray，light yellow，brown，and black umbilical color accounted for 19%，12%，9%，and 3% respectively. The average 100-grain weight was 24. 54 g，and the coefficient of variation was 25. 93%. In all tested pea resources，the average grain protein content was 36. 89%，and the coefficient of variation was 4. 17%. The mean value of grain fat content was 6. 95%，and the coefficient of variation was 17. 12%. The 100-grain weight and fat content of the pea showed diversity. The pea with pink grain color and the two pea resources （WD-024 and WD-114） with protein content up to 41. 02% and low-fat content are excellent special resources for pea breeding with high protein and low fat in the future.
