Agronomical and molecular characterization of a diverse apricot (Prunus armeniaca L.) germplasm from the regions of Hodna and Aurès in Algeria
Despite the new apricot cultivars released from French and Spanish breeding programs are displacing the autochthonous Algerian cultivars in each area, there are a lot of local cultivars that still have a great interest and they are cultivated in the different areas. Some of them are difficult to identify and frequently the same name is given to different cultivars or a genotype is known with different names. These varieties were selected over the years for its adaptation to warm Mediterranean climate and they are a valuable plant genetic resource that must be protected. The objective of this work is the agronomical and molecular characterization of Algerian autochthonous apricot cultivars using SSR markers. Eighty four apricot cultivated accessions from the regions of Aurés (semi-arid) and Hodna (semi-arid to arid) in Algeria has been evaluated. These cultivated accessions included local Algerian cultivars and French and Spanish introduced cultivars. Results have showed the great diversity at phenotype and molecular level of this autochthonous Algerian apricot germplasm and the effectiveness of SSRs by the correct identification, detecting some synonymies and suggesting the origin of some autochthonous cultivars.
