SEED SOURCE VARIATION AND CHARACTER ASSOCIATION STUDIES FOR SEED AND SEEDLING TRAITS IN PONGAMIA PINNATA (L.) PIERRE

摘要

Variation and correlation studies were carried out for seed, pod and seedling traits among seed sources of Pongamia pinnata selected from natural populations on the basis of morphometric characters to identify suitable seed sources for incorporation in mass afforestation programmes. Significant variability and association was observed among seed sources for pod, seed and seedling traits. PB-7 recorded the maximum 100-seed weight, seed thickness, 100-pod weight, pod length, pod thickness and internodal length. Pod thickness, 100-pod weight, pod thickness, seed length, seed breadth, and seed thickness showed high and positive correlation with 100-seed weight. Seed sources PB-7, PB-2 and PB-16 were best on the basis of most of the characters.
