The purpose of this paper is to try to understand purple cotyledon hot pepper as a genetic marker character behavior and possible application in breeding. The six populations (P1, P2, F1, F2, B1 and B2) of the cross between purple (P1) and green (P2) cotyledon hot pepper inbred lines were sowed in nutritive cups to study the color heredity of cotyledon. The result showed that the cotyledon color was controlled by two pairs of nuclear genes which showed complementary effects, and green was dominant to purple. The purple cotyledon hot pepper was a good material to research on the heredity and variation of traits in hot pepper. And the purple cotyledon hot pepper was also a useful marker to identify purity of F1 hybrids.
