The location and effects of genomic regions for rust resistance in sorghum were determined. One hundred and sixty recombinant inbreds, which derived from a cross between QL39 and QL41, were used as a segregating population for genome mapping and rust resistance evaluation. Phenotypic data were collected in replicated field trials in two years. Interval mapping and non-parametric mapping identified four regions, each in a separate linkage group, associated with rust resistance. The region with the largest effect on rust resistance is on linkage group 10; it accounted for 40% of the total phenotypic variation.
