520			_aLeaf blight caused by Alternaria triticina is reported from India during sixties and known to cause heavy losses in early varieties of wheat. These varies (NP series) were later replaced with new improved varieties and the disease could not became much important later. However, the recent mapping of leaf blight pathogens in India revealed high percentage of Alternaria spp. associated with blighted samples. The pathogenicity tests so far conducted however failed to produce the disease. Keeping in view of this attempts were made to prove the pathogenicity of three isolates, IMI No.289962, 178784 deposited from India during 1985 and 1973 respectively and CS 1801, a reference culture from Varanasi. The conditions given during the test were same as described by Prabhu and Prasada during his original description of disease. The test was conducted on three cultivars, Bansi, A 9-30-1 and UP 262 under controlled glass house conditions. Typical symptoms of disease were produced on Bansi cultivars only by both IMI cultures, after seven days of inoculation. Besides, A 9-30-1 and UP262 the cuitivars namely Sonalika, Yangmai, Altar-84, Glenlea, Katepwa, ND 295 and Salamouni were resistant to A. triticina. The pathogen could infect the Bansi variety even at lower spore concentration of 2000 spores/mI and able to infect the plant even at first leaf stage. The isolate from Varanasi differed from IMI isolates in the morphological characters and measurements. The further tests on the pathogenicity of isolated and screening of genotypes by using IMI reference isolates are needed.
