Abstract

We propose a theoretical study of linkage analysis and QTL mapping in an autotetraploid species, with particular reference to potato. This will build on studies at SCRI of linkage analysis of tetraploid potato using dominant markers. Linkage analysis methodology for more informative codominant markers, QTL analysis by regression and interval mapping, and marker-assisted selection strategies will be investigated and applied to potato populations. Linkage analysis at the tetraploid level is necessary for breeding of potato cultivars for processing and table use. The work will accelerate the combining of genes for yield and quality with resistance genes already introgressed from wild species, thus benefitting the important UK potato industry. This project will also provide theory of importance to breeders of tetraploid grass species and alfalfa.
