An association mapping analysis of dormancy and pre-harvest sprouting in wheat

Seed dormancy and pre-harvest sprouting are important traits in bread wheat. Bi-parental populations have permitted the identification of several genes/quantitative trait loci controlling these traits, mapping to various bread wheat chromosomes. Here, we report the use of association mapping to uncover the genetic basis of both traits in a panel of 96 diverse winter wheat cultivars to establish the presence of marker-trait associations on many chromosomes. Potential candidate genes were identified by studying the gene content of the chromosome bins into which the major marker trait associations mapped.
