“…Khan et al ( 2008 ) were able to discriminate the origin of seven date samples (four from Pakistan and three foreign varieties) attending to its elemental composition (Ca, Co, Cu, Fe, K, Na, Ni, Pb, and Zn) and cluster analysis. (Johnson et al 2013 ). Very little information is available about the chemical composition and nutritional characteristics of the Spanish dates.…”

The elemental analysis of Spanish palm dates by inductively coupled plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry is reported for the first time. To complete the information about the mineral composition of the samples, C, H, and N are determined by elemental analysis. Dates from Israel, Tunisia, Saudi Arabia, Algeria and Iran have also been analyzed. The elemental composition have been used in multivariate statistical analysis to discriminate the dates according to its geographical origin. A total of 23 elements (As, Ba, C, Ca, Cd, Co, Cr, Cu, Fe, H, In, K, Li, Mg, Mn, N, Na, Ni, Pb, Se, Sr, V, and Zn) at concentrations from major to ultra-trace levels have been determined in 13 date samples (flesh and seeds). A careful inspection of the results indicate that Spanish samples show higher concentrations of Cd, Co, Cr, and Ni than the remaining ones. Multivariate statistical analysis of the obtained results, both in flesh and seed, indicate that the proposed approach can be successfully applied to discriminate the Spanish date samples from the rest

“…Larger fruit size has been the most desirable trait in case of date palm [2]. In the Western region of Saudi Arabia, large fruit size characteristic of the cultivar Anbarah from Al-Madinah is reported to be a unique variant found with relatively low frequency and a high polymorphic index [13].…”

“…The geographical dispersal of dates by seeds is the oldest and most prevalent; the progeny commonly are designated as seedling dates [1]. In the Americas, the first date palm plantings were from seeds carried from Spain and North Africa [2]. The date palm fruit is a drupe and exhibits a high diversity in texture, shape, color and chemical composition depending on the genotype, environment, season and cultural practices.…”

“…It has been estimated that there are 3,000 cultivars of date palm worldwide [8], but it is widely suspected that many of the names represent synonyms [2]. Saudi Arabia has a rich diversity of about 400 date cultivars, of which 10 varieties are popular, have a high consumer preference in different regions of the Kingdom [9] and are propagated by offshoots as commonly practiced by the farmers and also through tissue culture.…”

Abstract:A survey was conducted in 2011 in the major date growing regions of Saudi Arabia to identify and evaluate date palms with fruit characteristics preferred by the producers and consumers. The regions in the Kingdom surveyed for this purpose were Al-Zulfi, Al-Hassa, Najran, Al-Madinah Al-Munawarah and Al-Qassim. Seventy palms from seedlings were initially identified for the study based on the following fruit characteristics, i.e., fruit length, breadth, weight, color, taste, texture, sugar content, external appearance and also the market value. Subsequently, 12 palms (Al-Afiah, Duhiba, Adbah, Aliah, Shamshula, Masifat Al-Asedy, Suwaid, Batlyah, Al-Nassar, Hussan, Sukariyat Al-Zulfi and Al-Hamat) mainly from the Zulfi and Riyadh regions were found to meet the required standards with potential for commercial date farming. Among these, fruits of Adbah had the highest total sugars of 72.9% followed by Duhiba with a total sugar content of 71.9%. Fruit length was maximum (49.1 mm) in the variety Aliah, while the fruits of the variety Hussan recorded the maximum weight of 19.5 g. Furthermore, it is pertinent to mention that fruit size of the 12 selected cultivars was generally large and comparable to Majdool, a well-known date palm cultivar of North Africa. The fruits of the selected cultivars were also tasty and can be stored separately.

“…Conventional date palm breeding is restricted by a long juvenile phase and high heterozygosity. Relevant to this aspect, Johnson et al (2013) reviewed reflecting a contemporary look at the seedling date palms as a potential germplasm. Moreover, modern biotechnological approaches including in vitro embryo rescue techniques offer indispensable tools for date palm breeding through the production of interspecific hybrids.…”
