Abstract
A homozygous mapping population, consisting of doubled haploid (DH) oat (Avena sativa L.) plants generated through anther culture of F1 plants from the cross between the Finnish cultivar 'Aslak' and the Swedish cultivar 'Matilda', was used to construct an oat linkage map. Ten agronomic and quality traits were analyzed in the DH plants from field trials in 2005 and 2006. Leaf blotch (caused by Pyrenophora avenae) resistance was also evaluated in a greenhouse test with 2 different isolates. One to 8 quantitative trait loci (QTLs) were found to be associated with each trait studied. Some chromosomal regions affected more than 1 trait; for example, 4 regions affected both protein and oil content. This study gives valuable information to oat breeders concerning the inheritance of important traits, and it provides potential tools to assist breeding.
