Study of Comparative Morphology of Eight Cultivated Genotypes of Olea europaea L

The current study was designed to assess the comparative morphology of eight olive cultivars with different geographical origins and diverse genetic backgrounds, introduced a new climatic zone. morphological parameters (five exotic three domestic) (Bari Zaitoon-1, Bari Zaitoon-2, Favolosa (FS-17), Koroneiki, Balkasar, Ottobratica, Leccino, Arbequina) were compared at experimental area Department Botany, Islamia University Bahawalpur, Pakistan (29°24′0″ North, 71°41′0″ East, 401–421 feet above sea level). Plant height, number leaves/15 cm shoot, leaf size characteristics (leaf length, width, area, length/width ratio), shape (margin, axil, base, apex angles), pigments (Chlorophyll a, Chlorophyll b, total chlorophyll contents, carotenoids), phyllotaxy, color venation recorded. highest plant height (28 cm) obtained by Zaitoon-2 followed Zaitoon-1 (24 cm), both which are domestic cultivar Pakistan, while shortest (5 Koroneiki. Leccino displayed average leaves (17.8) on main BARI-2 (16.4) lowest score from Balkasar (10.4).
