Background/Objectives: To understand the nature and magnitude of character association relationships in segregating and non-segregating populations. Methods/Statistical Analysis: Phenotypic correlation coefficient of parents, F1s and F2s was calculated following formulae given by Panse and Sukhatme, (1967). Results/Findings: In case of parents and F1s, only pods per plant were positively and significantly associated with seed yield whereas in segregating populations (F2s), plant height, pods per plant and seeds per pod revealed positively significant associations with seed yield. Conclusion/Application: From the findings it is suggested that during selection, due weightage should be given for Plant height, number of pods per plant and seeds per pod by taking care of number of secondary branches, 100-seed weight and harvest index for isolating high yielding genotypes in pigeonpea.
