Abstract:
Correlation and path coefficients analysis was done over twenty-one genotypes of tomato to study the nature and magnitude of associations between yield and its various contributing characters. The genotypes were sown under randomized block design (RBD) in three replications at Regional Research Station Karnal, CCS Haryana Agricultural University, during the spring summer season of 2019-20. The observations were recorded for twenty-one parameters pertaining to the morpho-phenological, yield and quality traits in tomato. The correlation coefficients exhibited a significantly positive association, at both genotypic and phenotypic levels, for yield per hectare with number of branches per plant, plant height at maturity, days to 50% flowering, number of marketable fruits per plant, weight of marketable fruits per plant, total number of fruits per plant, pericarp thickness, polar diameter and fruit firmness. The statistics from path analysis revealed that the weight of marketable fruits per plant, total number of fruits per plant, yield per plant and equatorial diameter of fruits were the most propitious characters influencing the dependent variable viz. yield per hectare directly as well as indirectly.
