This research studied the genetic parameters of the pigment characters of rice. The experiments were conducted in two stages: establishment of base population through crossing between black rice with white rice and F1s were grown in the green house and F2 seeds in the field. Analysis of the suitability of segregation ratio calculated with the chi squared formula and the degree of dominance could be seen from the comparison between the dominant predictive value [h] and the additive predictive value [d] were carried out with SAS 9.2 software. The results showed that the character of purple pigment was controlled by two mutually complementary dominant genes with recessive epistasis (9:3:4) which follow the model of additive×additive ([m][d][i] and dominant×dominant ([m][d][l]) interaction. The action of black/purple pigment gene of rice was perfect dominance which was directed to the parent with purple pericarp pigment (black rice).
