Identification of some Date palm (Phoenix dactylifera) cultivars by fruit characters.pdf
Date palm (Phoenix dactylifera) was studied for the morphological, anatomical and phytochemical characters of fruit cultivars. These cultivars are Amhat, Barhy, Bint Aisha, Zaghloul, Hayany, Amry, Kuboshy and Samany. The Morphological, anatomical and chemical characters of fruit varied among the cultivars studied. Zaghloul cultivar exhibited the highest values of reducing sugar, total phenols, titrateable acidity, while Samany cultivar showed the highest value of total soluble solids. This study may be helpful for commercial utilization of date palm.
MORPHOLOGICAL DIVERSITY OF DATE PALM (PHOENIX DACTYLIFERA L.) IN EGYPT I-DRY DATE CULTIVARS
Systematical relationships of twenty one dry date cultivars growing in Egypt were addressed based on one hundred and one morphological characters of trunk, crown, leaves, fruits and seeds. The most important characters are arranged according to their systematic value. This is followed by a key to the dry date palm cultivar in Egypt. Fruit and seed characters are still the most important criteria to distinguish among date palm cultivars. The study concluded that there is a window of opportunity to conserve dry date cultivars. The active cultivation is vital to survival and a cultivar is soon lost for ever if it is not regularly propagated.
Date Palm Genetic Resources and Utilization - Volume 2: Asia and Europe
This important reference book provides a comprehensive assessment of date palm genetic resources and utilization in individual date-producing countries worldwide. The book is published in two volumes; each consists of 15 chapters written by prominent scientists of each country and supported with color illustrations and tabulated data. Volume 1 addresses date-producing countries within Africa and the Americas; whereas, Volume 2 pertains to countries in Asia and Europe. This volume presents the current status and prospects of date palm cultivation in the Asian and European continents. The Asian countries included are: Iran, Saudi Arabia, Iraq, Pakistan, Oman, Yemen, Israel, Kuwait, Qatar, Bahrain, Syria, Palestine and India. Europe is represented by Spain. Topics discussed in each chapter include cultivation practices, genetic resources and conservation, plant tissue culture, cultivar identification, cultivar descriptions, date production and marketing, processing and novel products and concludes with recommendations for further development. This volume ends with appendixes presenting available information on each of the above-mentioned countries pertaining to cultivar descriptions and distribution, commercial sources of dates, offshoots and in vitro plants and research institutes and scientific societies concerned with date palm research and production. The book is a valuable resource for students, researchers, scientists, commercial producers, consultants and policymakers interested in agriculture particularly in date palm industry. Readers can derive great benefit from the adoption of policies and practices discussed to enhance production and expand industrialization of traditional and potentially new date products.

So far, more than 400 date cultivars have been recognized in Iran. When introduced to different regions of Iran, these cultivars significantly produced different quality from those in the area of origin. Ongoing studies deal with comprehensive characterization of these cultivars and identifying more cultivars. The present study was carried out to identify more new genotypes for identity certification and to select the cultivars which best suit the packaging and processing industries. The experiment was conducted with more than 100 cultivars from different regions using a sample of 200 fruits for each cultivar. Of these groups, the number of dominant cultivars throughout the regions of Siahoo,

In order to determine the variation and the degree of diversity among the most well-known Saudi date palm (Phoenix dactylifera L.), this study applied various widely detectible fruit and seed features. The properties of the fruit and seeds were described using ten phenotypic traits. Eighteen date palm varieties from six production sites were used in this study (Ḥaʼil, Al-Madina, Al-Hassa, Al-Qassim, Kharaj, Najran). The data was analysed by Pearson r correlation. The principal components analysis (PCA) and UPGMA clustering were used to analyse the data set. According to PCA, the results showed significant variation among the analysed varieties. Our data shows that seed ratio varies among all varieties. The mean seed weight ratio varies between 4 and 13%. Varieties ‘Raziz’, ‘Lubab’ and ‘Wasily’ demonstrate higher seed ratio (over 10%). Whereas, Fankha depicts a 5 and 4% fresh and dry seed ratio. The statistical analysis indicates that the seed ratio in all 18 varieties is comparable ...

Characterization of date palm (Phoenix dactylifera L.) cultivars is valuable for identification, conservation and breeding programs. Three elite date palm cultivars (Taghyat, Tafsert and Talees) grown in one of the most important areas of date palm cultivation in southern region of Libya (Sabha, Ubari and Murziq). These cultivars were investigated throughout the physical characters of the fruit. The obtained results revealed that physical property of date palm fruit were affected significantly by different cultivars and geographical growing regions
Comparative Study on Five Sudanese Date (<i>Phoenix dactylifera</i> L.) Fruit Cultivars
Food and Nutrition Sciences, 2012
The date palm (Phoenix dactylifera L.) is one of mankind's oldest cultivated plants. A date palm fruit is an important component of the diet in most of the hot arid and semi arid regions of the world. The present study aimed at investigating the physical and chemical properties as well as microbiological characteristics of five date palm cultivars cultivated in Sudan. The results showed that the physical characteristics like fruit weight, length, flesh thickness, seed weight differed significantly between the various cultivars. Although most of the cultivars had similar chemical components, there were some few differences. However, the microbiological analyses proved that no significant differences were found among the cultivars. Gondeila 1.80 ± 0.10 5.29 ± 0.20 4.30 ± 0.25 0.30 ± 0.14 Values are means of triplicate determinations.

Six date varieties from Egypt, one `Deglet Noor' and four `Medjool' date accessions from California, and 66 accessions of `Medjool' date from Morocco, the country of origin of `Medjool' date, were examined using four sets of fluorescent labeled amplified fragment length polymorphism (AFLP) markers. A total of 402 AFLP bands were generated and 160 were polymorphic (39.8%). The 66 `Medjool' accessions from Morocco shared minimum 79% of genetic similarity. These results support the hypothesis that `Medjool' date is a landrace variety and not a genetically uniform variety. `Medjool' is the first confirmed landrace variety of date palm worldwide. This raises the possibility that other landrace varieties of date palm may exist in different date-growing areas and in centers of diversity. The confirmation of a landrace variety of date palm also has significant impact on future date palm germplasm…
