Abstract
A population of 228 recombinant inbred lines (RILs) from the wheat cross 'Ning 8331'/'Martonvasari 17' was used in the examinations. The testing of Type II resistance to Fusarium head blight was carried out in the greenhouse. In field trials (Hungary), the surface of wheat ears was completely inoculated by spraying. In the laboratory, the lines were screened with 35 microsatellite markers to reveal the inheritance of chromosome segments. Correlation and simple regression analysis were used to search for associations between the phenotypic and molecular data. Significant correlations were found between the Fusarium head blight resistance and 7 SSR markers. The head blight evaluations of the lines in the Type II resistance trial were associated with the Xgwm539 and Xgwm608 markers on the 2D chromosome, explaining 16.3 and 10.6% of phenotypic variance, respectively. Five markers proved to be linked with the seed infection levels of the lines in the field resistance trial. Four of these were located on chromosome 3B and one (Xgwm169) on 6A. For the Xgwm389, Xgwm493, Xgwm108, Xgwm533 and Xgwm169 primers the coefficients of determination (R2) were 11.0, 8.4, 7.2, 7.0 and 7.0%, respectively
