Location of genes for common bunt resistance in the European winter wheat cv. Trintella
Euphytica 186 (1), 257-264
Abstract: The location of new genes for resistance to common bunt in wheat is valuable for gene pyramiding in breeding. For this purpose, the genetics of the relatively high level of resistance in the European winter wheat variety Trintella was investigated using a doubled haploid mapping population of a cross between Trintella and the susceptible variety Piko. The population was scored for bunt infection in the field for 2 years following inoculation with a mixture of teliospores of Tilletia tritici and T. laevis. A genetic map consisting of 29 linkage groups was constructed using polymorphic simple sequence repeat markers. This map was used for QTL analysis, and in both years, results indicated that resistance to common bunt could mostly be attributed to a gene on chromosome 1B, near to the centromere and closest to marker Xgwm273 on the short arm. Additionally, in 2008, smaller QTL effects were ascribed to chromosomes 7A and 7B, and another smaller QTL effect to chromosome 5B in 2009 only.
