Dissection of three quantitative trait loci for grain size on the long arm of chromosome 10 in rice (Oryza sativa L.).

ABSTRACT:

Background

Thousand grain weight is a key component of grain yield in rice, and a trait closely related to grain length (GL) and grain width (GW) that are important traits for grain quality. Causal genes for 16 quantitative trait loci (QTL) affecting these traits have been cloned, but more QTL remain to be characterized for establishing a genetic regulating network. A QTL controlling grain size in rice, qGS10, was previously mapped in the interval RM6100-RM228 on chromosome 10. This study aimed to delimitate this QTL to a more precise location.

Method

A total of 12 populations were used. The ZC9 population comprised 203 S _1:2 families derived from a residual heterozygous (RH) plant in the F ₉ generation of the indica rice cro
