Abstract: The appearance quality is an important aspect of rice qualities, which decides the customer choice and, to some extent, affects its price in market. The study was conducted to detect quantitative trait loci (QTLs) for seven associated appearance quality traits in rice, viz., grain length (GL), grain width (GL), grain length/width ratio(LWR), grain thickness(GT), chalkiness grain ratio(CGR), chalkiness size (CS), and chalkiness degree(CD), using a backcross recombinant inbred lines (BILs) derived from the backcross between an elite japonica variety(Japan), Koshihikari (japonica), as a recurrent parent, and an indica variety(India), Kasalath. Resultantly, a total of 22 QTLs controlling the seven traits were detected and located on eight chromosomes, which could explain 5.65%-29.20% of total phenotypic variance. Interestingly, the same genomic region of QTLs tightly linked to R2232 on chromosome 5 controlled four associated the appearance quality traits, both the one tightly linked to C1448 on chromosome 3 and the one closely linked to G200 on chromosome 6 controlled affect three traits,respectively, showing that the three genomic regions have important effect on the appearance quality in rice. In a word, the QTLs detected in this study and the molecular marker linked to them can be useful for the improvement of appearance quality through the marker assisted selection (MAS) in rice.
