Chromosomal location of introgressed weedy rice segments and quantitative trait loci for seven agronomic and two domestication traits in weedy rice CSSLs.

<p>The linkage map developed in a recombinant inbred line (RIL) population from the cross between Bengal and PSRR-1 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0130650#pone.0130650.ref021" target="_blank">21</a>] was used to determine the substituted segments and coverage of rice genome in each CSSL. The bars to the right side of chromosomes indicate the substituted weedy rice chromosome segments in the CSSLs. The presence of a QTL is inferred when there is a significant difference between the means of each CSSL and the recurrent parent at p<0.01 using the Dunnett’s test. When multiple CSSLs with overlapping chromosome segments are significantly different from the recurrent parent for the trait values, the QTL location was narrowed down to smaller region using substitution mapping [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0130650#pone.0130650.ref017" target="_blank">17</a>]. Bars with a red border indicate the PSRR-1 alleles responsible for increased trait values.
