Abstract

Field studies were carried out to investigate the reaction of fifty six cotton genotypes against leafhopper, Amrasca devastans Dist. The results indicated that CCHO5–2, RAH 100, J.TAPLI (G. arborium) and VIKRAM were found resistant due to the presence of morpho- physical characters like hair density and length of hair on midrib and lamina, and recorded lowest injury index value (1.00) with least damage to leaves.
