Abstract
Morphological cluster analysis in fifty eight genotypes of tomato revealed considerable genetic diversity and grouped genotypes into 12 different clusters. Choosing parents from the most distinct clusters, with elevated cluster means and demonstrating high performance, can be utilized in hybridization programs to create high-yielding varieties. The highest percentage contribution to total genetic divergence was noted from average fruit weight, followed by fruit diameter and fruit length, indicating that selecting one or two superior genotypes from such varied clusters based on these traits and crossing them would yield greater heterosis.
