Abstract: A set of nine inbred lines were crossed in diallel design and developed 36 single cross hybrids. These 36 hybrids along with 9 parents and three checks were evaluated in randomized block design with three replications. The heterosis over mid parent (MP), better parent (BP) and standard check was observed for quantitative and quality traits. The highest positive significant heterosis at all the three levels for seed yield per plant was exhibited by MGG 347 x KM 11-564. This cross combination also revealed highest per se performance for this trait (36.61%). Another hybrid WGG 42 x RM 12-13 exhibited maximum positive significant heterosis at all the three levels with highest per se performance (31.41%) for seed yield per plant. LGG 543 x KM 11-564 exhibited maximum economic heterosis with highest per se performance for seed yield per plant (g).
