Evaluation of some seeded dry date palm grown under Aswan climatic condition

الملخص EN

This study was carried out through 2014 and 2015 seasons to evaluate some seeded dry date palm grown in Aswan governorate, Egypt.

Their local name, Abd elnaby 1, 2, 3, El-masry 1, 2, Khaled ebn elwalid, Abas gaffer, Radwan and Ali Aamer date palm compared to Sakkoty cv.

which is one of the commercial dry cultivar vegetative traits.

Yield components and fruit quality as well as numerical evaluation and molecular genetics were investigated.

The obtained results indicated that Ali Aamer date palm type had the highest values of most studied vegetative traits compared to the other studied types.

On the other hand, the least values of such traits were recorded of Sakkoty cultivar.

El-masry 2 type gave the highest yield components followed by Khaled ebn elwalid and Radwan types, whereas, Abd elnaby 1 gave the least one compared to other studied types.

No significant difference was found among Abd elnaby 2, Ali Aamer and Sakkoty cultivar.

Khaled ebn elwalid type had the highest values of fruit quality followed by El-masry and Abas gaffer types, whereas, Sakkoty cultivar gave the lowest one compared to the other studied types.

As the numerical evaluation of date palm types, it could be arranged in a descendingly order as follows: Khaled ebn elwalid (88.2), El-masry 2 (81.5), Ali Aamer (80.9), Abas gaffer (79.3), Abd elnaby 3 (77.5), El-masry 1 (77.0), Radwan (75.8), Abd elnaby 2 (74,9), Sakkoty (70.7) and Abd elnaby 1 (70.1 units).

The ISSR data were used to estimate the genetic similarity among the nine date palm strains by using UPGMA computer analysis.

The highest similarity index (0.95) was recorded between Ali Aamer and El-masry 2 strains, while the lowest similarity index was detected (0.5) between Abd elnaby 1 and Abas faffer.

A dendrogram for the genetic relationship among the nine date palm strains was found.

These results revealed that seeded date palm named Khaled ebn elwalid, Elmasry 2, Ali Amer, Abas gaffer and El-masry 1 are considered promising to be new strains to obtain a high yield with good fruit quality compared to Sakkoty date palm cultivar.
