QTL Mapping of Brown Rice Rate Using Chromosome Single Segment Substituted Lines in Rice
摘要
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.关键词
