Abstract:

An experiment was conducted using 18 F4 progenies of tomato along with two bacterial wilt resistant varieties as checks (Palam Pink and Palam Pride) to determine the inter-relationship among component traits and their direct and indirect contribution on marketable fruit yield. The trial was laid out in Randomized Complete Block Design with three replications at Vegetable Research Farm, Department of Vegetable Science and Floriculture, CSK HPKV, Palampur during summer-rainy season of 2016. Two susceptible checks, Roma and Marglobe, were planted at every alternate 11th row in the experiment to establish the severity of the disease. Estimates of correlation coefficient revealed that marketable yield per plant was positively and significantly correlated with total and marketable fruits per plant, gross yield per plant and pericarp thickness indicating that selection based on these characters either in combination or alone will result in identifying the genotypes having high yield potential. Path coefficient analysis showed that marketable fruits per plant and average fruit weight had the maximum positive contribution (direct and indirect) towards marketable yield per plant; hence these traits require special attention to improve upon marketable yield and other component traits.
