Cotton leaf curl disease (CLCuD) is main constraint to American cotton (Gossypium hirsutum) cultivation which is one of the most important cash crops in northwestern India. At this time no single variety/hybrids have available that’s having resistant reaction towards cotton leaf curl disease. Screening of germplasms is a basic step to explore resistant source. With this objective, the germplasm comprising three hundred seventy seven genotypes were evaluated against cotton leaf curl disease at CCS HAU Cotton Research Station, Sirsa during kharif 2013 to 2015.  None was found immune/disease free or highly resistant. However, thirty four genotypes were found resistant, one hundred thirty four expressed moderately resistant reaction and one hundred forty four were found moderately susceptible. Forty nine genotypes were observed susceptible and sixteen were found highly susceptible to CLCuD.  The resistant genotypes may be used for variety/ hybrid development or as a donor of resistant genes.
