Three crosses were made between high protein, wrinkleseeded, green cotyledon pea ( Pisum sativum L.) lines and low protein, smooth‐seeded, yellow cotyledon pea lines. Comparisons of yellow vs. green cotyledon F 3 lines and paired comparisons of yellow vs. green cotyledon seeds from within segregating F 3 lines were made to determine the relationship of yellow vs. green cotyledon color to percent protein and other seed characters. Analogous comparisons were made to determine the relationship of cotyledon shape, smooth vs. wrinkled to percent protein. The yellow cotyledon pea seed did not differ from the green cotyledon pea seed in percent protein, whereas the wrinkle‐seeded peas averaged about 3% higher protein than the smooth‐seeded peas. The wrinkle‐seeded peas also exhibited a reduction in seed weight, percent starch and seed yield as compared to the genetically comparable smooth‐seeded peas. However, the weight of protein per seed was similar for both smooth‐ and wrinkleseeded lines.
