Abstract: Field experiment were carried out in RRTTS, Semiliguda, Koraput during 2017-18 and in AICRP on vegetable research in OUAT, Bhubaneswar in 2017-18 and 2018-19 respectively. The present study was undertaken with the objective to determine the degree of association between yield and it`s component characters over three environment. Forty tomato advance lines along with 7 check varieties were evaluated for identifying their efficiency with respect to 15 yield and yield attributing traits. The result from the pooled analysis of correlation study revealed that highest positive correlation both at genotypic and phenotypic level was between yield and numbers of truss per plant (rp-0.738, rg-0.802) followed by number of fruits per plant (rp-0.679, rg-0.695), number fruit per truss (rp-0.554, rg-0.592). Among the other component traits number of fruits per plant shows positive correlation with number of fruits per cluster (rp-0.804, rg-0.840), average fruit weight with number of flower per cluster (rp-0.732, rg-0.794).
