In this study, yield and yield components were analyzed for correlation and path analysis. The results revealed that, the pod yield per tree exhibited significant and positive association with pod weight (0.6417 and 0.6729), pulp weight (0.6324 and 0.6698), shell weight (0.6096 and 0.6520), fibre weight (0.6005 and 0.6458), pod length (0.5712 and 0.6142), seed weight (0.4660 and 0.4755), pod thickness (0.3714 and 0.4162) and pod width (0.3317 and 0.4311). While, the pod length (0.0674), pod thickness (0.0866), pod weight (0.0240), pulp weight (0.2121), shell weight (0.3169), seed weight (0.4787), fibre weight (0.2821) and number of pods per tree (0.3494) exhibited positive direct effect on pod yield per tree. Since the pod length, pod weight and pod thickness are the measures of pod size, the larger the pod, the heavier the pulp weight. Hence, these yield components can be used as criteria in selection programme for developing elite cultivar in tamarind.Keywords: Correlation, path co-efficient analysis, tamarind, yield and yield components.
