The present study was aimed to identify the chilli varieties through its morphological characters identification. Tamil Nadu Agriculture University (TNAU) released chilli varieties viz., CO1, CO2, K1, K2, KKM1, PKM1, PMK1, PLR1, CCH1(hybrid), CA97 (male) and Sln1 (female) were used. The experiment was carried out during the period from August 2011 to February 2012. There are 33 morphological characters (plant height, leaf density, flower position etc.,) were studied in identification. Among the above, only 8 qualitative morphological characters (Intensity of anthocyanin coloration of nodes, stem pubescence, plant growth habit, leaf color, leaf pubescence, flower position, anther colour and calyx annular constriction) and 3 qualitative characters (plant height, leaf length and leaf width) were found as the important morphological characters for identification. Other characters (Seedling: Anthocyanin colouration of hypocotyl, hypocotyl pubescence, Stem colour, Plant: Anthocyanin etc.,) were of secondary importance for identification of varieties. Some of the characters were recorded in quantitatively and the cluster was formed from the recorded quantitative data, based on similarity in the characters the varieties were grouped into three main clusters at 76% similarity level. In cluster one PMK1, PLR1 and CO2 were diverged from other genotypes at 87.5% similarity. The rest of eight genotypes formed a second cluster and third cluster showing the 80% similarity level and thus useful for varietal identification.
