Tomatoes are an important vegetable grown all over the world. Association study of yield and
related traits plays a vital role in improving the production of tomato cultivars. Eighteen tomato
genotypes were selected and sown in the field area of the Department of Plant Breeding and
Genetics, University of Agriculture Faisalabad, using a randomized complete block design with
three replications. Data was collected on various yield-related traits to find the associations
between yield and yield-related traits. The results showed significant variations among
genotypes for traits such as plant height, stem diameter, number of fruits per plant, fruit length,
number of clusters per plant, number of fruits per cluster, fruit diameter, average fruit weight,
fruit flesh thickness, pericarp thickness, and number of locules. Correlation analysis unveiled
both positive and negative correlations between these traits, providing insights into their
interrelationships. Furthermore, path coefficient analysis elucidated the direct and indirect
effects of each trait on fruit yield per plant. Results indicated that traits such as plant height,
stem diameter, number of fruits per plant, number of clusters per plant, fruit flesh thickness,
fruit diameter, fruit length, fruit weight, pericarp thickness, and number of locules significantly
influenced fruit yield per plant. These findings contribute to the understanding of trait
associations and can guide the development of high-yielding tomato varieties through targeted
breeding efforts
