Identification of molecular markers linked to Fusarium head blight (scab) resistance genes in wheat.
Abstract
Aims of the project: 1) The production of F1-derived doubled haploids from crosses between two resistant (Frontana and CM 82036) and one susceptible cultivar (Remus). Doubled haploids are produced by pollination of wheat florets with maize pollen, embryo rescue and colchicine treatment, 2) Those doubled haploid populations will be checked for the expression of Fusarium head blight resistance traits in field trials after artificial inoculation as well as for tolerance against the Fusarium mycotoxin deoxynivalenol in a germination test on toxin containing agar, 3) Different types of DNA markers will be tested for polymorphism in these populations. Segregation analysis of polymorphic DNA markers will be carried out and, 4) The availability of data on Fusarium resistance and resistance to toxin together with information on molecular markers will allow to determine quantitative trait loci.
