Evaluation of breeding programs susceptibility for two important forage crops using DNA Barcoding

Abstract EN

This investigation was carried out to identify and evaluate Medicago sativa andTrifolium alexandrinum probability for breeding program based on two bar-coding genes (rbcl and Cox1 genes).

Identification of Medicago sativa Baladi 1 was performed through rbcl and Cox1 genes.

Medicago sativa Baladi 1 was identified as Medicago sativa voucher G00199095 ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit (rbcL) gene, partial cds; chloroplast (Sequence ID: KJ204375.1) and Medicago sativa voucher Ahrendsen_23 for rbcl and Cox1 genes respectively.

Identity values were recorded with 90% of identity for alfalfa, Baladi 1 Genotype ribulose – 1/5 – bisphosphate carboxylase / oxygenase large subunit (rbcl) gene (sequences ID: KJ206375.1) also, identity values were recorded with 91.24% of identity for alfalfa Baladi 1 Genotype, cytochrome c oxiddase bubunit I gene (cox 1) (sequence ID: KJ 204375.1).

Trifolium alexandrinum Helaly genotype was identified as Trifolium alexandrinum (Sequence ID: HM850407.1) and Trifolium alexandrinum voucher K-016Hv (Sequence ID: KU234213.1) as rbcl and Cox1 genes respectively.

Affiliation of genetic origin was detected for Trifolium alexandrinum with 100 % of similarity with origin source which indicate highly possibility for applying breeding programs comparing with Medicago sativa which reflect the lowest genetic similarity with origin source.
