Abstract: The field and lab study was targeted to identify the resistant clones of Gmelina arborea aganist the defoliator Calopepla leayana and evaluate the existence of most suseptible and less susceptible clones. Study analyzes through morphological individuality of different genotypes with reference to C. leayana along with the confirmatory study of different clones and identified most susceptible and less susceptibleclones through leaf micromorphology and chemical study. Resistant clones were identified through morphological study as most susceptible (08) and less susceptible (07) numbers of clones. Among them following six clones were identified as most susceptible GA006, GA 002 and GA 081 and GA 023, GA 034, GA 095 less susceptible. Where leaf micromorphology and chemical study was also resulted same for the selection of above clones.
