التوصيف الجزيئي للخوخ البري (Prunus cerasia Blanche)‎ المنتشر في محافظة اللاذقية

الملخص EN

This research aims at studying the molecular characterization of Prunus cerasia Blanche genotypes spreading in Lattakia, using RAPD (Random Amplified Polymorphic DNA) technique to demonstrate their genetic fingerprinting.

Total DNA was isolated from juvenile green leaves, followed by PCR chain reaction using 18 random primers.

Fifteen RAPD primers out of 18 showed high efficiency in detecting the genetic variability of the genotypes.

The primers produced 110 total bands, 51 of them show high genetic differences with 46.36% percent of variation.

The study confirmed the relationship between genetic diversity and geographic location of the types.

Furthermore, the study shows clearly genetic affinity between types from one location and genetic difference between types from locations disparate geographically.

This variation constitute a variable genetic base that can be utilized in the breeding and improvement programmes of almonds.
