The experiment was conducted at Forest College and Research Institute, Tamil Nadu Agricultural University; Mettupalayam situated at 11° 19‟ N longitude, 76° 56‟ E latitude at 300 MSL during January - December 2010. The study indicated significant differences among the selected families for various growth attributes. Among 20 open pollinated families evaluated, three families viz., FCRIMD 11, FCRIMD 14 and FCRIMD 15 exhibited consistent superiority over growth periods for height, basal diameter and volume index. Genetic divergence studies resulted in grouping of the selected families into six clusters which indicated the existence of adequate genetic divergence. Among the clusters, cluster I was the largest with 10 open pollinated families. While the maximum intra cluster distance was recorded in cluster II. The intra and inter cluster distance revealed that maximum inter cluster distance was recorded between cluster I and VI which indicated the presence of wide genetic distance between Melia dubia open pollinated families. Among the various growth attributes, volume index contributed maximum towards genetic divergence followed by plant height. These two characters could act as a reliable indicator for future improvement programme in this economically important species. Genetic analysis of the families indicated adequate variability in the population. The PCV and GCV estimates exhibited superiority of volume index followed by basal diameter and plant height. Whereas, plant height and volume index exhibited moderate heritability. The genetic advance was high for volume index followed by plant height which indicated the reliability of these two parameters for inclusion in future improvement programme.
