| Summary: | The present investigation was undertaken with an objective to study the magnitude of heterosis involved in 32 hybrids
obtained by crossing four (female) x eight (male) genotypes in L x T fashion along with their 12 parents and two
standard checks (JLT-408 and PRACHI) evaluated during summer, 2019-20 at Oilseeds Research Station, Latur. Data
were recorded on yield and its different contributing traits. The analysis of variance for experimental design revealed
significance differences among the parents, hybrids and parents vs hybrids for most of the characters indicated the
presence of genetic variability among the experimental material. The crosses viz., SWETHA x V-25, V-34 x TBS-12,
V-32 x TBS-7, SWETHA x R-26 and SWETHA x TBS-12 found with high heterobeltiosis and standard heterosis over
check JLT-408 and PRACHI for seed yield along with other yield contributing traits. Significant heterobeltiosis and
standard heterosis for seed yield were observed for the majority of yield and yield attributing traits. Selection of high
heterotic hybrids with high per se performance would be reliable in the improvement of sesame.
