Abstract:
The present investigation entitled “Identification of superior crosses for heterosis of seed yield and its attributing traits in sesame (Sesamum indicum L.)” to study heterosis in 21 hybrids obtained by crossing 7 x 3 genotypes in L x T fashion and their 7 lines, 3 testers and 1 standard check were evaluated in RBD with 2 replications during Rabi 2022-23 at ATS, Latur. The magnitude of heterosis for seed yield per plant was varied from -18.45 and -19.75 percent (TBS-07 x V-18) to 68.72% and 50.13% (TS-13 x V-22) over mid parent and better parent respectively, from -27.59% (TBS-07 x V-18) to 39.08% (TS-11 x V-22) over the check AKT-101. The crosses, TS-11 x V-22 (32.97, 43.53, 39.08%) and TS-13 x V-22 (50.13, 68.72 and 33.11%) recorded highest magnitude of significantly positive heterosis over mid parent, better parent and standard check AKT-101 respectively, for seed yield per plant.
