Based on single seed descend method a recombinant inbred lines population consisting of 190 lines was created by crossing two rice varieties with similar apparent amylose content, Nipponbare (japonica) and 9311 (indica) by QTLs for brown rice protein content(BRPC) and milled rice protein content (MRPC) with a genetic linkage map including 202 SSR, CAP and STS markers were identified. By composite interval mapping method in two environments sites (Sanya Hainan Province, China and Hefei Anhui Province, China), a total of nine QTLs were identified, indicating that rice protein content was controlled by multiple genes. qBRPC1.3 was detected at the two sites with high stability, explaining 9.4% of total variation. The interval RM578-RM10596 on chromosome 1, controlled BRPC and MRPC, explaining 6.4% and 5.7% of total variation, respectively.
