In present investigation the experimental materials consisted of parents and their 45 F1’s and 45 F2’s derived by crossing 10 diverse sesame genotypes (GT-3, GT-4, GT-6, AT-338, AT-324, IC-132186, GT-10, T-11, GJT-5 and GTF-1) in a half-diallel fashion, were evaluated during Kharif 2022 at Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh. The parents recorded with highest seed yield per plant were AT-324 (6.45), GJT-5 (6.23) and AT-338 (5.77). Similarly, top five cross combinations for seed yield per plant were AT-338 × AT-324 (11.54), GT-6 × GT-10 (10.22), GT-3 × GT-4 (8.47), GT-4 × T-11 (7.28) and GT-4 × IC-132186 (6.99).
Sesame, half-diallel, combining ability and heterosis
Among parents GT-4, AT-324, GT-3 and AT-338 offer the best possibilities of exploitation for the development of improved pure lines with enhanced seed yielding ability as being recorded with high per se along with high gca effect for most of the traits. Three cross combinations AT-338 × AT-324 (P4 × P5), GT-6 × GT-10 (P3 × P7) and GT-3 × GT-4 (P1 × P2) performed consistently in F1 generation for high per se performance, significant sca effects along with high heterobeltiosis and standard heterosis. These parents and cross could be utilized further in multiple crossing programme or hybrids could be further evaluated to be released as variety.
