Date palm (Phoenix dactylifera L.) is one of the oldest fruit bearing perennial trees classified under the genus of Phoenix in Arecaceae (Palm) family. The natures of date palms with their long productivity have an indispensable socio-economicsignificance and contributions in agricultural sustainability. The date palm is a food and income source for societies particularly in the desert and also it has medicinal, cultural, ecological and environmental values. Date palms are dioecious with a wide range of phenotypic variations. Therefore, evaluation of date palm cultivars using morphological characters at regional as well as global level is critically necessary for sustainable utilization of itsgenetic resources as well as for genetic improvement and conservationprograms. The aim of this study is to assess the phylogenetic relationships of ate palms date palm cultivars cultivated at Melka Werer research centre. A total of 45 morphological traits were used to assess phylogenetic relationships of eleven date palm cultivars. All traits showed mean variations amongthe cultivars.Principal component analysis on the first component revealed 37% variation in vegetative and reproductive traits data combined together and 29% and 32% of variations was observed in separate vegetative and reproductive morphological traits data respectively. Among 45 morphological traits 43 traits exhibited significant differences at p <0.05 inanalysis of variance and also 23 traits showed significant variances at p <0.05 inhomogeneity of variance analysis among cultivars. Besides, dendrograms were constructed based on combined vegetative and reproductive traitsdataand in separatevegetative and reproductive traits data and showed the genetic relationships between date palm cultivars.Generally, this study clearly display the phenotypic variations between cultivars and also the resultis important as baseline for documenting and further agronomic traits studies of date palm cultivars particularly in Ethiopia.

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 in fresh and dry fruits. The result suggests variation among the numerous features due to dissimilarities and heterogeneity. However, the obtained results also propose the clustering and grouping of closely related features, e.g., weights of fresh and dry fruits. Eventually, it is suggested to conduct additional research on Saudi date palms utilizing more phenotypic traits in order to have a better understanding of the pack of morphological descriptors.

The study has been carried out at experimental station of National Institute of Agronomic Research of Algeria (INRAA) of Sidi Mehdi Touggourt zone. The plant material consists of six cultivars of Triticum durum Dest. The experimental plan has Randomized Complete Bloc Desing (RCBD) with four replication and nineteen biometric characters. The objective of this study is the agro-morphological characterization of six durum wheat cultivars (Tritcium durum Desf.) from the Oued Righ region. Nineteen agro-morphological parameters were considered in this study. Moreover, the analysis variance (ANOVA) and the principal component analysis (PCA) highlighted a distinct variation between the studied cultivars, some of which showed good traits such as: precocity yield per plant, thousand grains weight and earing earliness, it’s the case of Fritissi with 40.8g; 52.38g and 102 days respectively. This inter-cultivar variability observed through morphological characterization requires use of biochemical and molecular markers in order to confirm achieved results.
