Metroglyph and index score analyses of 25 germplasm lines and 5 cultivated varieties of Gossypium arboreum cotton were carried out. There was a wide morpho- logical variation followed by germplasm lines and cultivated varieties. However, seven distinct morphological groups could be distinguished, particularly on the basis of plant height and yielding ability. Within group, morphological variations were of high order. Majority of the lines were included in the group characterised by medium stature plants and medium yield. The variability pattern of the lines in fitth and sixth groups resembled that of cultivars.
