Identification of date palm male cultivars by the electrophoretic pattern of pollen soluble proteins

الملخص EN

The soluble proteins of pollen grains from date palm cultivars .

Sakuic.

Scleg, Maktumy, Khashkur , Shagra-El-Oassim .

Succari .

Mcncifi , Setri , Khalas , Nabut Zamel , Nabut Sif.

Kha shrurn.

Barhi.

Dehcini a nd Khudari were separated by slab gel ele ctrophoresis.

The pollen protein palterns were representative to the cultivars .

Soluble proteins of pollen grains were separated into 3\ protein bands, bUI o nly.

7 to 9 hands were found in each cultivar.

High degrees of similar ities wer e found among Maktumy a nd Khudari (75% ).

Succari and Khashrarn (67%) and Nahut Zamil and Khashram (67%).

Khashkar was totally different from Sakaci and Maktumy, while Mukturny was different only from Khashram .
