Abstract

GRAIN QUALITY is dependent on cooked and uncooked grain size and grain wide and also grain shape. As rice GRAIN QUALITY is an endosperm trait, its inheritance can be more complicated because the genetic expression of an endosperm trait in cereal seeds is conditioned not only by the triploid endosperm genotype, but also by the diploid maternal and cytoplasmic genotype and epistasis effects. Molecular marker aided selection technique for GRAIN QUALITY would accelerate breeding progress by increasing selection efficiency. In order to map the QTLs for GRAIN QUALITY in rice and estimate the effect of each QTL in phenotypic variation, 63 advanced backcross lines (BC2F 5) derived from cross between IR64 as recurrent parent and Tarom molaei as donor parent, investigated in International Rice Research Institute (IRRI). The phenotypic traits under study included: Uncooked kernel length (UKL), Uncooked kernel width (UKW), UKL/UKW, Cooked kernel length (CKL), Cooked kernel width (CKW), CKL/CKW, Kernel elongation ratio (KER), Kernel length difference (KLD). We analyzed 235 SSR markers for parental survey by agarose and polyacrylamide gels, through them 114 markers showed polymorphism and assigned for genotyping. Transgressive segregation was observed in all traits. UKL showed significant correlation with UKW, UKL/UKW, CKL/CKW. We identified one QTL for each of traits including KLD, CKW, CKLICKW, two QTLs for CKL and KER, three QTLs for UKL, five QTLs for UKW, and seven QTLs for UKL/UKW.
