Random Amplified Polymorphic DNA (RAPD) was used to evaluate genetic diversity among 11 Yemeny pomegranate types. Samples were collected in 2004 from three main regions: east, middle and north of the country (Rada, Hada and Saada). PCR amplificati on of pomogranate DNA with 30 random primers generated 1013 bands, 118 of them were polymorphic 11.5%. Results showed that the genetic diversity within the tested types was limited. Similarity values ranged between 59 –96 % with a mean of 79 %. Statistical analysis showed that the types can be divided into two clusters: cluster 1 with Orkobi and Mellies types found in the Hada region; cluster 2 includes nine types belonging to the Saada and Radaa regions .High similarity (90–96%) was obtained with Khazemy, Liessy 1, Liessy 2, Taefi, Ahmer and Balady types. Whereas, some types could be considerd as separate cultivars due to their high genetic diversity such as, Orkoby and Mellies (Hada region) in addition to Bohssom, Sommaty and Liessy 3 in the Saada region.
Study was conducted in five locations as the important areas for pomegranate cultivation and production in Yemen, during the period (15/1– 15/8/2004). Eight accessions of local pomegranate were used in this study: Taefi, Orkobi, Mellies–Hada, Khaz emy, Sommaty, Kodary, Chiny and Mellies– Raudha in addition to the wild pomegranate type (Socotria). The morphological characters were determined for leaves, flowers,fruits and seeds. The chemical analysis for juice was also assessed. Maximum rate for fruit weight was 527.3 gm for Kodary accession, whereas fruit Juic varied between 49.5–63.2%, while peel / fruit was varied between15% in Taefi and 35.9 % in Chiny, whereas the peel thickness varied between 1.5–4.2 mm. The Scotria was found to be evergreen, and flowers around the year. Kazemy accession gave higher fruits number/tree with rate 246.7. The greatest rate of T.S.S and Vitamin C were 18.57% and 11.12 mg respectively for Chiny accession, and the highest content of organic acids in these accessions was 0.54 % for Taefi.
