Thirty-eight cultivars and breeding lines of wheat, Triticum aestivum L., carrying one or more known resistance genes were evaluated for reaction to Hessian fly, Mayetiola destructor (Say), in Morocco. Genes for resistance included Marquillo and H1 through H13 (except recessive h4). Wheats were evaluated in the field at four locations; percentage of susceptible plants and number of live larvae per susceptible plant were criteria used to measure levels of resistance. Significant differences in percentage of susceptible plants and number of larvae occurred among wheats with different resistance genes and among locations. Only wheats having H5, H7,H8, H9, H11, and H13 genes were significantly more resistant than susceptible checks 'Newton' and 'Bennett'; only H5, H11, and H13 genes conferred a high level of resistance (antibiosis) at all locations. Evaluation of the wheats in a greenhouse confirmed field tests. Of the known resistance genes in wheat, only H5, H1, and H13 would be of value in breeding for Hessian fly resistance in Morocco.
