Molecular mapping of the rust resistance gene R4 to a large NBS

... Rust resistance gene R4 in the germplasm line HA-R3 was derived from the Argentinean open-pollinated variety ‘Charata INTA’ (Gulya 1985). The origin of its rust resistance gene can be traced to wild annual Helianthus species. Charata INTA was selected from the cross between Russian lines and wild su ...

Quantitative trait locus

A quantitative trait locus (QTL) is a section of DNA (the locus) that correlates with variation in a phenotype (the quantitative trait). The QTL typically is linked to, or contains, the genes that control that phenotype. QTLs are mapped by identifying which molecular markers (such as SNPs or AFLPs) correlate with an observed trait. This is often an early step in identifying and sequencing the actual genes that cause the trait variation.Quantitative traits are phenotypes (characteristics) that vary in degree and can be attributed to polygenic effects, i.e., the product of two or more genes, and their environment.
