Varietal and Species-Interrelationship between Cultivated and Wild Sesamum

The relative distance between the five cultivated varieties of Sesamum indicum viz., AVT-3, Rama, Krishna. 8–67 and Local and the wild S. mulayamum was studied on the basis of similarities and dissimilarities of parameters as morphology, seed isozyme profiles and total protein profiles prior to undertaking a hybridization program. The dendrogram revealed that the varieties AVT-3, Rama and Local were distant from S. mulayamum but the grouping of the varieties Krishna and B-67 with S. mulayamum indicated greater chance of introgression of the desired insect resistance by hybridizing the wild with either Krishna or 8–67.
