This study aimed to explore diversity in dwarﬁng tendencies, determine the correlation of measured traits with dwarﬁng, and identify and select promising dwarf candidates as potential scions or rootstock cultivars. Growth habit, vegetative attributes, fruit physicochemical characteristics,and leaf stomatal densityof 19 Iranian pomegranate cultivars, which have been collected across the country and established in the Yazd pomegranate germplasm, were assessed. Results showed that the cultivars diﬀered in almost all measuredtraits. The tree height and canopy width, current year’s shoot, and internode length were within the range of 1.974.6 m, 1.534 m, 1541.5 cm 1.963.39 cm, respectively. Moreover, a positive correlation was observed between tree height and internode length (r= 0.55), whereas a negative correlation was obtained between stomatal density and tree height (r= 0.44). Based on characteristics measured for the vegetative growth, ‘Malas No. 1 Saravan’ and ‘Torosh Nar Riz Zirab’ proved dwarﬁng habit. ‘Rabab Poost Ghermez Neyriz’,a commercial cultivar, showed semidwarﬁng growth and ‘Khajei Ghasrodasht Fars’, ‘Shahsavar Seydan Marvdasht’, ‘Bihaste Ravar’, ‘Bihaste Sangan Khash’, ‘Torosh Goli Naz Behshahr’ and ‘Anar Siah’ resulted in vigorous trees. This preliminary study found promising dwarf and semidwarf genotypes at Iran’s pomegranate germplasm.
