The genetic regularity and molecular marker of pericarp pigment in black rice were investigated byanalyzing the F1 and F2 populations from the crosses of black pericarp line（Hei B）×white pericarp line originatedfrom northeast of China. The results showed that plants were all black pericarp in the F1 population. While in theF2 populations, the segregation ratio of black pericarp plants and white pericarp plants was 3∶1. This suggests thatthe trait of black pericarp was completely controlled by one dominant gene. The gene controlling black pericarptrait, designated BP, was mapped in chromosome 4 based on BSA analysis and linkage mapping using 128 SSRs and 45 INDELs scattered on whole chromosomes. The BP was located between R4M23 and R4M43, with a distance of 10.2cM and 14.6c M, respectively.
