The experiment was undertaken to study the magnitude of heterosis of 32 hybrids obtained by crossing 4 (female) x 8 (male) genotypes in L x T fashion including their 12 parents and 2 standard checks (JLT-408 and PRACHI). The ANOVA revealed significant differences among parents, hybrids and parents vs hybrids for most of the characters, indicating the presence of genetic variability. The crosses SWETHA x V-25, V-34 x TBS-12, V-32 x TBS-7, SWETHA x R-26 and SWETHA x TBS-12 showed high heterobeltiosis and standard heterosis over both checks for seed yield and yield contributing traits. Significant heterobeltiosis and standard heterosis observed for majority of yield and yield attributing traits.
