QTLs （Quantitative trait loci）affecting main rice eating quality characters were analyzed using a recombinant inbred（RI）lines derived from a cross of Asominori × IR 24 and its RFLP map with 293 molecular markers by single marker analysis and interval mapping.Twenty eight QTLs for grain eating quality were found,and another six QTLs that could exist were also found.According to anlysis of correlation and link of QTLs, main eating quality traits existed relationship significantly.Molecular marker C445 on the chromosome 4affected chew-streng,sticky,taste-sense,eating taste and cool meal quality of cooked rice.Marker G1314B on the chromosome 2 affected hardness,taste-sense,sticky and eating taste quality of cooked rice.G952B on the chromosome 11was molecular marker of chewstreng,hardness and eating taste quality of cooked rice.
