Tomato (Solanum lycopersicum L.) is one of the most important solanaceous vegetable crops grown widely all over the world. Its cultivation in commercial growing pockets of Himachal Pradesh is severely affected due to bacterial wilt disease caused by Ralstonia solanacearum Smith. Resistant genotypes have been developed at various research centers, located within the country and abroad but these genotypes were not found suitable for growing in Himachal Pradesh as these are lacking in one or other characteristics. The present investigation entitled “Variability and association studies in F4 progenies of tomato (Solanum lycopersicum L.)” was undertaken by evaluating 18 bacterial wilt resistant F4 progenies viz., (Palam Pride × BWR-5)-1-15, (Palam Pride × BWR-5)-1-16, (Palam Pride × BWR-5)-2-3, (Palam Pride × BWR-5)-2-6, (Hawaii 7998 × Palam Pride)-2-7, (Hawaii 7998 × BWR-5)-3-1, (CLN2070B-1 × 12-1)-2-8, (CLN2070B-1 × 12-1)-2-16, (CLN2123A-1 × BWR-5)-3-6, Avtaar-1-3, Avtaar-1-13, Avtaar-1-15, (12-1 × BWR-5)-1-7, (12-1 × BWR-5)-2-2, (12-1 × BWR-5)-2-13, (12-1 × BWR-5)-2-14, (12-1 × BWR-5)-2-18 and (12-1 × BWR-5)-2-19 along with two bacterial wilt resistant standard checks (Palam Pink and Palam Pride) to identify the promising progenies on the basis of nature and extent of genetic variability, association among component traits and marketable yield and direct and indirect effects of each of the component traits on marketable yield. These genotypes were evaluated in Randomized Complete Block Design with three replications in summer-rainy season’2016 at the Vegetable Research Farm of the Department of Vegetable Science and Floriculture, COA, CSK HPKV, Palampur. To ascertain the severity of the disease, two susceptible checks, Roma and Marglobe were planted at every alternate 11th row in the experiment. Analysis of variance revealed significant differences among the genotypes for all the traits except plant survival. The maximum marketable yield per plant was produced by the progenies Avtaar-1-3 (0.87kg) followed by (12-1 × BWR-5)-2-18 (0.76kg), (Hawaii 7998 × BWR-5)-3-1 (0.75kg), (Palam Pride × BWR-5)-2-3 (0.70kg), (Palam Pride × BWR-5)-1-16 (0.69kg), (CLN2070B-1 × 12-1)-2-8 (0.66kg), Avtaar-1-15 (0.63kg) and (12-1 × BWR-5)-2-14 (0.62kg). These top yielding progenies also excelled in many other horticultural traits. For most of the characters high to moderate PCV and GCV estimates along with high heritability and genetic advance were observed. The estimates of PCV were higher than corresponding GCV for all the characters studied which indicated that the apparent variation is not only due to genotypes but also due to the influence of environment. Marketable yield per plant was positively and significantly correlated with total and marketable fruits per plant, gross yield per plant and pericarp thickness at phenotypic and genotypic levels. Days to 50 per cent flowering, locules per fruit, plant height and total soluble solids had significant negative association with marketable yield per plant at genotypic level. Path coefficient analysis revealed 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.
