Genetic diversity of Libyan date palms cultivars using amplified fragment length polymorphism and biochemical analysis

Phoenix dactylifera L. is a flowering plant species commonly known as the date palm and widely cultivated in most Middle East countries, including Libya. The present study analysed biochemical genetic diversity of fully mature eight Libyan cultivars grown different regions using amplified fragments length polymorphism (AFLP) technique. Six pairs AFLP molecular marker combinations were utilised to discriminate genotypes. Fruit dimensions (length x diameter) varied based on type; Majhool Alheelo fruit had highest value (15.29 cm2), while lowest was for Alkhadraya fruits (7.9 cm2). Reducing sugar content ranged from 10.4 per cent flesh dry weight Umfetity 61.2 Sufeer-genab, which also showed percentage (P%=4.9), Alkhadarya (P%=0.519). phylogenetic tree indicated that distantly related Alhamraya Alhelo. two closely Alsaeedy Show Alkhadarya, regions. Our results indicate nutritional not matched with growing region.
