The paste viscosity attributes of starch, measured by rapid visco analyzer(RVA), are important factors for the evaluation of the cooking and eating qualities of rice in breeding programs. To determine the genetic roots of the paste viscosity attributes of rice grains, quantitative trait loci(QTLs) associated with the paste viscosity attributes were mapped, using a double haploid(DH) population derived from Zhongjiazao 17(YK17), a super rice variety, crossed with D50, a tropic japonica variety. F...
