The remaining cultivars ‘Khazar’, ‘Ghaem-3’, ‘Pouya’ and ‘Hashemi’ individually formed next clusters which were more isolated from the other cultivars. Low similarity indices were observed between ‘Pouya’ and ‘Hashemi’ (0.59) and among ‘Hashemi’ with either of cultivars ‘Neda’, ‘Champa’, ‘Amol-3’ with 0.61 similarity index which indicated more divergence. Crossing between the genotypes with low similarity coefficient will manifest high heterosis. As regards to higher quality status of ‘Hashemi’ among cultivars, it is essential that to pay more attention to it in hybridization programs
