Variability and association studies in pod and seed traits in half-sibs progenies of Thespesia populnea in Tamil Nadu

The present study was carried out to identify superior candidate plus trees of Thespesia populnea across its natural distribution in Tamil Nadu and pods were collected for tree improvement work. The pod and seed physical parameters viz., 100 pod weight, number of seeds per pod, 100 seed weight, seed length, seed breadth and germination per cent were studied. The seeds collected from Bhavanisagar (FCRI TP 12), Periyampatti (FCRI TP15) and T. Nagar (FCRI TP 16) region were superior in all traits studied compared to other regions of Tamil Nadu. These progenies can be utilized for quality seedling production in nursery.
