This study was conducted to evaluate the response of cotton cultivars against the fungus.In this research the fungus were isolated in seedling stage and purified in seedling stage from the cotton fields of Golestan province. and then fungus was detected using morphological data. Confirmed Alternaria species was performed using nucleotide sequence data of ITS – rDNA region and sequencing of the part of endo poly galacturonase gene. Accordingly, isolated Kb2 isolate with fungus
