Sixty-one sunflower (Helianthus annuus L.) multihead inbred lines including one check were evaluated to study the morphological variations for twelve characters by using Mahalanobis D2 statistics. These genotypes were grouped into 7 clusters, among which the cluster I with 52 genotypes was the largest followed by cluster II with 4 genotypes. Maximum inter cluster distance was recorded between cluster II and VII (740.36) followed by clusters I and VII (426.99). Hence hybridizing between these divergent groups may lead to higher variation in segregating population. Among 7 clusters, IC-597575, EC-601938, EC-640337, IC-438395 and SS-2038 were most divergent lines compared to other and crosses may be affected among the genotypes of these clusters to get more heterosis among the hybrids. The study revealed that the characters viz., Plant height (cm), Oil content (%), No of branches per plant contributed more to the total genetic divergence in the genotypes.
