الملخص EN

This study was carried out during 2015 (in the Western Areas of Syria), to determine the percentage of protein and oil in the seeds of some distribution phenotypes of Prunus ursina K.Y.

in different regions of Westrens of Syria.

six natural distribution sites were determined (Duerbsndiana, Alnabeen, Alshohtte, Helata, Btmazah and Wadeheleen), and 35 trees were determined as samples.

The fruits were collected and seeded at full maturity phase.

Percentage of protein and oil was also determined.

Data was taken for ANOVA analysis using the statistical Software Costat.

Comparision of averages at significance level 5% was made.

The percentage of protein ranged between 20.9% in KA5 seeds and 37.7% in J5 seeds that showed significance over other genotypes.

The percentage of oil ranged between 27.7% in J5 seeds and 45.6% in K3 seeds that showed significance over other genotypes.The affinity tree using the software NTSYS showed the distribution of studied genotypes into two groups(A,B).

groups A belongs to genotypes (J7, J6, K4) prevailing in two geographically distant sites (Alnabeen and Duerbsndiana), whil The other genotypes belong to group B and prevail in all study sites
