Abstract

Diversity analyses on ninety two genotypes of sesame using ten morphological characters were studied. Results indicated 
that ten clusters were formed wherein maximum inter cluster distance was observed between cluster IX and X (239.87).  
Simultaneously crossing of these 90 genotypes with Co-1 and TMV-5 was carried out. The 180 hybrids generated using two 
lines (CO 1 and TMV 5) with these 90 genotypes, upon evaluation, indicated five elite hybrids namely TMV 5 X bardur 
local (B)(217.49 percent), TMV 5 X bardur local (W) (198.38 percent), CO 1 x RT 172 (163.47 percent), TMV 5 x Rama 
(161.04 percent) and TMV 5 x MT-10-23-3 (155.57 percent) significantly yielded than the standard check TMV 7 and their 
male parents were found to be from the  cluster I  which were moderately divergent (19.09) among them.
