Overview

Phenotypic evaluation demonstrates high yield potential and disease resistance across diverse tomato genotypes, suggesting strong candidate lines for crop breeding programs.

Key Points

  • To assess the phenotypic variability, mean performance, and trait relationships of diverse tomato genotypes to identify superior candidates for crop improvement.
  • Evaluated 36 experimental tomato genotypes alongside 3 standard check varieties under natural field conditions.
  • Analyzed agronomic traits, quantitative genetic parameters, and trait associations using correlation and multivariate analysis.
  • Significant phenotypic variation occurred across genotypes, with candidate lines V32, V22, and V33 outperforming check varieties with high yield potential and low bacterial wilt incidence.
  • Fruit yield demonstrated strong positive associations with the number of fruits per plant, fruit diameter, and individual fruit weight.
