Assessment of Genetic Divergence for ProcessingTraits in Tomato

摘要

The present investigation on genetic diversity for some physico-morphological and biochemical traits in tomato were conducted at the Vegetable Research Farm, Department of Vegetable Crops, Punjab Agricultural University, Ludhiana. The materials for investigation comprised 35 genotypes of tomato. The genotypes were grouped into six clusters. Genotypes of clusters IV were observed to be the most divergent from genotypes included in clusters III and VI; and clusters III and V. Ample genetic divergence has also been observed between the genotype comprised in cluster V and I, and cluster V and II. The genotypes in the cluster I and II were closely related to each other for most of the characters. Among the clusters with high genotypic values, genetic divergence was more between genotypes of clusters IV and genotypes of clusters III, VI. It may be worthful to initiate a hybridization programme by taking suitable parents from these divergent clusters and practicing selections in segregating generations torecover suitable superior recombinants.
