A heterogeneous wheat line ( Triticum turgidum L.) submitted to the USDA‐SEA world collection of wheats by J. C. Santiago, Portugal, was reselected at Purdue University on the basis of resistance to Hessian fly ( Mayetiola destructor Say), biotype D. We designated our selection ELVA (CI 17714). From chromosome homologies and plant characters it was classified as a Triticum turgidum L. Resistance to Hessian fly from Elva was transferred to common wheat ( Triticum aestivum L.) by backcrossing. Three of the resultant resistant lines were analyzed for number of genetic factors controlling resistance to biotype D at 20 C. Progenies from individual F 2 plants and BC 1 F 1 plants from crosses between the resistant lines and the susceptible ‘Arthur’ were classified for reaction to Hessian fly. In two lines, resistance appeared to be controlled by two linked dominant genetic factors, either conferring resistance. The third line most likely contained a single dominant genetic factor.
