Ahmad, A.C. Russell, D.L. McNeil] Genetic regulation of host resistance in lentil to ascochyta blight was found to be controlled by two complementary dominant gene pairs in wild species of Lens ervoides and Lens odemensis. Both genes must be present in the dominant form, whether homozygous or heterozygous, for complete resistance. When one pair of genes is present in homozygous recessive state, they mask the effect of the other dominant gene pair and ultimately makes the lentil plant susceptible to the pathogen, a case of duplicate recessive gene interaction. The results also suggested that in Lens culinaris ssp. orientalis, ascochyta blight resistance was controlled by a single dominant gene pair. The possible utilization of wild Lens species to improve the genetic resistance of cultivated lentil to ascochyta blight is reported and it is suggested that interspecific hybrids should be included in lentil breeding programmes aiming at ascochyta blight resistance.
