Seventy eight seedling progenies of a sweet tamarind type collected from Dindigul region were planted at HorticulturalCollege and Research Institute, Periyakulam during September 2005. These seedling progenies in pre bearing stagewere evaluated to assess the variability existing in respect of growth parameters viz., tree height, girth and canopyspread. Among the three characters studied, canopy spread exhibited highest correlation with girth (0.61) than treeheight (0.21). Tree height having highest correlation with girth (0.46) than canopy spread (0.21). In Bivariate fitanalysis, TIS40, TIS 49 and TIS 52 were recorded the highest performance and TIS 53 had the lowest performanceamong the 78 progenies studied. In hierarchical clustering analysis, totally six groups were identified. In this, highestperformers TIS 26, TIS 38, TIS 40, TIS 49 and TIS 52 were came under one group and the lowest performers TIS5, TIS55, TIS 7, TIS 16, TIS69, TIS 72, TIS 24, TIS70, TIS 25, TIS 53, TIS 11, TIS 17, TIS 22, TIS 21 and TIS 46 wereclassified under the another group. Other four groups are moderately performing in nature. TIS 36 having dwarfstatured and compact canopy may be exploited for easy harvesting and it can also be possible to accommodate morenumber of trees within the specified area leading to high density planting.
