In order to clarify the genetic mechanism of grain shape traits for large panicle indica rice line,R1126,a set of recombinant inbred lines,which contain 185 lines,was developed by using R1126 crossed to the japonica rice line,Nipponbare. By measuring the grain shape traits include grain length（ GL）,grain width（ GW） and grain thickness（ GT） in two years field experiment,combining with the genetic map constructed with SSR and SFP molecular markers,QTL associated with grain shape traits were analyzed. Total ten QTL associated with GL,GW and ...
