Abstract:

In order to identify the chromosomal model and studying the nucleic type of local accessions and introduced cultivars of almonds; a chromosomal study was conducted the laboratory experiments have been executed in both Homs- and Aleppo-Agricultural Scientific Research Centers. on the somatic cells at the equatorial phase of indirect division after seed germination and mirestem-root isolation, the chromosomal formula were identified into three groups according to the genetic divergence or convergence among accessions and cultivars as follows:

• First group is: 2sm + 14m = 16 = 2n included local accessions 4, 11 and 12 and cultivars Flornbas, Braniss, Klozarro.
• Second Group is: 4sm + 12m = 16 = 2n included accessions 2, 3, 5 and 6.
• Third Group is: 6sm + 10m = 16 = 2n, accessions included 1,7,8,9. and 110 and cultivar fersil.

Genetically identification of the chromosome types of the tested accessions and cultivars were varied in terms of quantity and quality characteristics (length and type of chromosome, IAs%, R=GC/PC, ....). It was found that Almond chromosomes were characterized by two types of chromosomes only (i.e. chromosome has either central or sub-central point).
