Sesame is well recognized for good quality edible oil due its high PUFA content, antioxidant properties, excellent nutritional and medicinal properties. The present investigation aims at analyzing the variability among promising parents and newly developed genotypes of sesame on the basis of 8 morphological characters. PCV exhibited a bit higher values but maintained a close relation with GCV for all the traits, indicating low G×E interaction. Additive gene action was prominent for the traits like no of capsules/plant, seed yield /plant, and primary branches/plant. Highly significant positive phenotypic correlation coefficient was observed between seed yield and its four attributes namely plant height, branches per plant number of capsules/ plant and 1000 seed weight.
