Implication

Randomized trial evaluates genetic traits and associations in tomato genotypes for yield improvement, indicating potential for enhanced production.

Key Points

  • The aim is to evaluate genetic variability and trait associations of indeterminate tomato genotypes for yield improvement under protected cultivation.
  • Evaluated 57 indeterminate tomato genotypes over two years under protected conditions.
  • Performed analysis of variance and Mahalanobis D2 statistics for genetic divergence.
  • Used Multi-Trait Genotype-Ideotype Distance Index to select elite genotypes.
  • All traits showed significant differences among genotypes; fruit weight and number of fruits per cluster had high heritability.
  • Clusters identified revealed significant genetic divergence; Cluster VI excelled in yield and earliness.
  • The first five principal components explained 83.3% of total variation, indicating strong trait correlations.
