التوصيف الجزيئي لبعض أصناف و أصول اللوز في سورية باستخدام المؤشرات ال SSRs

الملخص EN

The objective of this study was to characterize and determine the genetic variation among twelve cultivars and four rootstocks, belonging to Amygdalus genus in Syria using the simple sequence repeats (SSRs) marker.

It was found that 154 alleles were identified by using 26 primer pairs, and the proportion of the specific ones was 30.52%.

In addition, it was revealed that all the studied SSR loci produced polymorphic alleles.

The average of PIC, He and Ho were 0.58, 0.61, 0.31, respectively.

Dendogram based on SSR analysis was divided into three groups.

The first and the second groups contained local and introduced almond cultivars, whereas the third one included the rootstocks.

The distribution of almond cultivars and rootstocks into groups and the variation between them resulted of the distribution of alleles produced on the three microsatellites loci UPD98-021 (264bp), UDP96-010 (87bp) Pchgms5 (265bp).
