Yield and fiber quality are most important and complex trait as they depend on interaction of genetic architecture of plant and environment. To achieve this objective, two parents FH153, KZ191 and their F2 population were evaluated for the existence of inter-relationship of characters under study during 2014-2015, at University of Agriculture, Faisalabad. The experiment was carried out in a randomized complete block (RCB) design with three replications. Data were recorded for Plant height (cm), number of sympodial branches, number of monopodial branches, pedicel length (mm), number of bolls per plant, number of seed per boll, boll weight (g), ginning out turn (%), fiber fineness (μ/inch), staple length (mm), fiber strength (g/tex), seed cotton yield (g). The obtained data were analyzed through correlation analysis at 0.01 and 0.05 significance level. The traits under study showed considerable range of phenotypic variability. The parent FH153 had maximum mean value for all traits under observation expect fiber strength. The parent KZ191 showed maximum fiber strength (21.1 g/tex). The F2 population of parents (FH153×KZ191) had minimum results for all traits. The results also showed positive association of characters with each other except staple length showed negative association with monopodial branches per plant, fiber strength and seed cotton yield.
