The present study was conducted on five ber (Ziziphus mauritiana Lamk) cultivars (Komethry, Pakstany, Um-sulaem, Toffahy and Peyuan) grown in Saudi Arabia during 2005 and 2006 seasons. The aim of the present study was to investigate fruit properties (fruit weight, length, diameter, shape, specific gravity, seed weight, pulp percentage, total soluble solids (TSS), acidity percentage, TSS/acid, vitamin C content total, reducing and non-reducing sugars). Peyuan cv. had the heaviest fruit weight, fruit volume and reducing sugar content however, it was the lowest in pulp percentage and non-reducing sugars among the five cultivars in both seasons. Toffahy cv. had highest fruit diameter and seed weight while, had lowest TSS %, vitamin C and total sugars values. Um-sulaem cv. had highest acidity percentage and vitamin C content and lowest fruit weight, length and TSS/acid. On the other hand, Pakstany cv. had highest percentage of both pulp percentage, TSS, total and non-reducing sugars. Finally, Komethry had the longest fruit. The molecular characterization and fingerprint identification of the ber cultivars was conducted using the ISSR (Inter-Simple Sequence Repeats) technique. The ISSR technique was able to uniquely characterize and differentiate between the five ber genotypes. Moreover, the genetic similarity tree showed that the cultivar Um-slaem is genetically distant from the other four cultivars and the two cultivars Pakstany and Komethry were genetically identical.

    • "mg/100 g, respectively. Obeed RS et al. (2008) also investigate fruit properties on five ber (Ziziphus mauritiana Lamk) cultivars (Komethry, Pakstany, Um-sulaem, Toffahy and Peyuan). However, a large number of jujubes grow in Bangladesh which has high nutritional value, but food composition table for all Bangladeshi fruits is not available that is necessary for national nutritional planning as well as monitoring of an individual's nutrient intake.

    ABSTRACT: The present study was designed to investigate the nutritive values of five different varieties of locally grown jujubes (Zizyphus Mauritiana) namely Apple kul, Bau kul, Narikeli kul, Comilla kul and Local/Deshi sour kul. The objective of this study was to determine the nutrient content and to compare nutritional quality among the above varieties of jujube and to give awareness to the people about the actual nutrition content of different varieties of jujubes in Bangladesh. This study observed that carbohydrate, protein, fat, energy, moisture, total sugar, reducing sugar, fiber, ash, carotenoid and vitamin C content of different jujube fruits are ranges between 4.70-10.01%, 1.02-1.20%, 1.02-2.20%, 43.91- 57.95%, 84.18-89.23%, 3.57-9.72%, 2.01-7.42%, 1.41- 6.97%, 2.85 -3.23%, 459.20-246.77 μg and 32.98-42.91 mg/100 gm of edible portion respectively. Among the five varieties of jujubes, apple kul contain highest amount of protein, carbohydrate, total sugar, reducing sugar, ash, carotenoid and energy but lowest amount of moisture. On the otherhand, local/deshi kul contain highest amount of vitamin C, moisture and fat but lowest level of carbohydrate, energy, total sugar, reducing sugar, crude fiber and ash. In compare with these jujube fruits Narikeli kul also contain the lowest amount of protein (0.85%), fat (1.02%) and carotenoids (246.77 μg/100 gm). Surprisingly, Comilla kul contain the highest amount of crude fiber (6.97%) but lowest amount of vitamin C. This result suggest that more attention should be given to the apple kul for yield and production of jujubes in large scale, which contain the highest percentage of nutritive values.

    ABSTRACT: Indian jujube germplasm characterization, evaluation and improvement are fundamentally based on morpho-physiological traits. The lack of break through has been due to under utilization of genetic variability for superior quality and high yield potential. We report the extent of genetic diversity and relationships among 22 putative Ziziphus mauritiana varieties using nuclear ribosomal DNA and RAPD polymorphism. A hybrid protocol of DNA isolation was developed to obtain high molecular weight DNA. Ten RAPD primers generated 101 markers and detected intra-specific variation amounting to 85.15 % polymorphism in banding patterns delineating them into four main clusters and variety Tikadi as a distinct out group. Besides, internal transcribed spacer (ITS) length variations, single nucleotide polymorphism and insertions/deletions (INDELS) in nuclear rDNA region delineated test varieties and revealed lineages with GenBank reference sequences of Z. mauritiana. The novel gene sequences exhibiting nucleotide variations have been submitted to NCBI database and assigned accession numbers from JQ627029 to JQ627050. Higher values of Nei’s genetic diversity (h), Shannon information index (i) and genetic distance analysis validate higher genetic diversity among Indian jujube varieties. The genetically distinct varieties of different phylogenetic clades of RAPD and ITS phylogram can be effectively utilized as parents for crop improvement.
