Abstract: The simple correlation coefficients were calculated in F2 populations of three superior crosses viz., ML 267´LGG 528, MGG 390´LM 95 and LM 95´EC 362096 for fourteen quantitative characters. Correlation studies among the fourteen characters indicated different degrees of association between characters. Both positive and negative correlations were found between different pairs of characters. Knowledge on inter-relationship among yield components, water use efficiency and heat stress tolerance related traits may facilitate breeder to decide upon the intensity and direction of selection pressure to be given on related traits for the simultaneous improvement of these traits. Correlation studies in F2 populations of three identified superior crosses revealed that improvement in seed yield coupled with drought and heat stress tolerance could be brought through component characters like number of pods per plant, number of clusters per plant, number of pods per cluster, plant height, branches per plant, SLA, SCMR, SLW and relative injury.
