Genetic analysis of pericarp thickness in tomato

Genetic analysis of pericarp thickness in tomato

Journal of Maharashtra Agricultural Universities 16(2): 181-182

The genetic nalysis of pericarp thickness in tomato was performed using fifteen inbred lines. Out of 105 hybrids, 14 exhibited significant positive heterobeltosis. The heterosis percentage ranged from 43.75 to 33.33. The pericarp thickness of hybrids ranged from 0.23 to 0.70 cm. The general and specific combining ability variances were signiicant. The parents 5, 7, 12, 14 and 15 were good general combiners. Out of 105 hybrids, 20 exhibited significant sca effects in positive direction. The estimates D, H1, H2 and E were significant. The value of F was positive. The narrow sense heritability was high for pericarp thickness in tomato.
