Abstract

In a 6 x 6 full diallel experiment conducted during 1996 - '97 with sesame (Sesamum indicum L.) of numerical and
graphical analyses days to maturity was found highly heritable with additive effects, whereas plant height, branches,
capsules/plant. seeds/capsule, 1000 seed weight and seed yield/plant were moderate to low heritable with non-additive
effects in the form of dominance. Impact of season on the genetic expression was non-significant and the 6 parents 'TMV
5' mutant, 'Vinayak mutant, 'S1266', 'RJS108', 'SI3260' and 'Madhavi' showed genetic diversity for all the 7 characters.
The predominance of both additive and non-additive gene influence showed the high genetic potential ofthe 6 parents for
exploiting desirable economic heterosis.
