The infestation of insect pests reduces crop production by 30 to 45 percent, and if preventive measures are not taken, the yield losses can exceed 70 percent. Therefore, the current study was designed to study the inheritance of cotton plant characteristics which provide the resistance against insect pests. A full diallel set of crosses were done among five cultivars of cotton viz: RH-362, VH-137, Cocker-CQ, B-598 and Karishma. All possible crosses including self and reciprocal among parents at precautionary measures and limitations to avoid contamination of genetic material at time of crossing. The F1 population was cultivated collectively in a field using a three-replication, randomized full block design. The seeds of 20 F1 hybrids and five parents were raised in field and data were recorded for gossypol and trichome. Genetic analysis was conducted according to the method outlined by Hayman and Jinks. The graphical representation of variance (Vr) and Co-variance (Wr) suggested over dominance type of gene action for trichomes whereas number of gossypol glands showed partial dominance of an additive gene action type.
