Study of protein pattern behavior of cultivars of date palm

Abstract

The current study has been performed to detect the differences among date palm cultivars in terms of protein patterns as well as the cultivars distribution on the variation tree .Results revealed that the cultivars of date palm varies accordingly in their protein profile on both numbers and fragment orders compared with molecular weight standard .Three distinguished groups have been categorized according to the molecular weight of the fragment ,first group was between 97.295-107.500 KDa, second group flanked between 71.144-83.610KDa,while the third group was within the range of 29.048-67.883KDa.Shawethy cv. Showed the highest molecular weight with a single fragment which was 107.500 KDa .Hence the study proved the variations among tested cultivars within the range of 66.6-100%.Bath Aljouzy and Asabeh AlAros cultivars were the most closest cultivars depending on the number of fragment and their weight .Cluster analysis of the tested cultivars revealed that the distribution of date palm cultivars followed tow distinguish groups , Shawethy cultivar was segregated into an individual group, while the lowest cluster distance was observed between Leloy and Myasee cv.
