Résumé
The present investigation was conducted during two successive seasons (2013and 2014) to evaluate some physical and chemical fruit properties of chosen twelve seedling date palm trees among 250 palms and Sewy , Soltany varieties grown at El-Qasr village in Bahariya Oasis conditions according to panel test survey. Evaluation was conducted through the two stages of fruit development (maturity and ripening stage) these palm trees gropes according to (dry, semi-dry and soft). Evaluation results reveal that in dry date palm seedling trees and Soltany variety. Palm 3 superior than Soltany variety and other seedling date palm trees in fruit physical properties (fruit weight, flesh weight, fruit length, fruit diameter, fruit size) and chemical properties (total sugar and TSS in ripening stage). It gave convergent results in total yield compared with Soltany variety. The result for semi dry date palm group showed that palm 1 was superior than Sewy variety in physical fruit properties and total sugar. It gave convergent results in total yield and TSS compared with Sewy variety. Whereas, soft date seedling grope palm 4 gave the highest values in fruit physical and chemical properties and recorded high weight for yield in both seasons. Palm 3 in dry groups, palm 1 in semi dry and palm 4 in soft seedling date palm trees can be the beginning of new varieties with good characteristics under Bahariya Oasis conditions.
