Abstract: The field experiments were conducted at All India Coordinated Cotton Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri for three consecutive years from 2015-16 to 2017-18 for studying biochemical and morphological factors responsible for resistance against jassids on cotton. Results indicated that based on infestation of jassids, biochemical and morphological traits of cotton, the genotype GISV 272 is recommended as resistant source against jassid. Correlation studies revealed that trichome density of cotton genotype had negative direct effect (- 0.996) on jassid infestation. Thickness of leaf midrib has positive and direct effect (0.947) on jassid infestation. Thickness of leaf lamina, gossypol content and total phenols showed significant and negative (-0.973, -0.974 and -0.928) correlation with jassid incidence. The peroxidase activity and polyphenol oxidase activity was higher in GISV-272 and showed significant positive correlation with jassid incidence (0.977 and 0.938). Nitrogen and phosphorus content showed significant positive (0.854 and 0.986) correlation with jassid incidence.
