توصيف شكلي لبعض الطرز المتفوقة من المحلب Prunus mahaleb L. المزروع في سورية

Abstract EN

This research work was carried out during 2007-2010 in some Syrian governorates such as Homs, Damascus countryside and Edleb.

Twenty two morphotypes of cultivated, P.mahaleb were evaluated and four superior morphotypes were selected: (HG5, RS3, EM2, ET6),which distinguished with good quality.

The statistical analysis of data was done by SPSS 18 program, and the results showed that the type ET6 was recorded the greater value for the fruit's dressing percentage 81%, seed's dressing percentage 61%, productivity of fruits by tree 59.25 kg, and productivity of seed's core 6.71 kg\tree.

So, this type has been surpassed morally on other types except EM2, while the type HG5 was recorded the greater value for the seed's weight(for 100 seeds) 12.25 g, and it surpassed morally on other types except RS3.

Also the relationship among that types was determined by Cluster Analysis program.

So, they were classified into two groups, the first contains: (HG5, RS3), the second contains:(ET6, EM2).

Both groups were correlated by ratio of 67.5%, which clearly shows that there is a correlation among the studied morphotypes even though they belong to different natural spreading sites
