Abstract: Brown rice rate is one of the indexes for rice milling quality measurement.In this study, the inherit-ance of brown rice rate was characterized using 119 chromosome single segment substitution lines ( CSSSLs ) derived from Nipponbare and Guangluai 4.One-way ANOVA and Dunnett's test were employed to compare the difference between CSSSLs and the recurrent parent Guangluai 4.We detected 2 QTL(P≤0.001) for brown rice rate which were primarily mapped on chromosome 6 and 9 by substitution mapping.Both of the allele from donor parent Nip-ponbare had positive effects.The additive effects of 2 QTL were 1.49% and 1.32% respectively, with additive effect percentages 1.89%and 1.68%.These results provide useful information for exploring and using new brown rice rate related QTL,and also have important economic value for increasing brown rice rate and actual production of rice.
