Under the frame of an EEC - INCO-DC programme, 'APRIMED' research project is under development with the objective to characterize, to preserve and to identify the apricot genetic resources in part of the Mediterranean Region (Turkey, Spain, Italy, France, Morocco and Tunisia). An integrated and multidisciplinary approach divided in 3 main tasks has been developed. Prospection and preservation of genetic resources - During the prospection, 103 accessions have been identified in Morocco and 58 in Tunisia; while the preservation of 430 clones has been performed in France, 279 in Italy and 94 in Turkey. Characterization - A phenotypic characterization under UPOV descriptor has been achieved on 204 clones. A molecular characterization has been applied onto a set of 83 accessions by means of 4 microsatellites. Assessment of agronomic performances - The agronomic value has been accessed onto a total of 242 clones and partly investigated on 158 clones - Flower fertility has been investigated on the productive clones. Male sterility and interincompatibility groups have been identified. Chilling requirements and Floral anomalies measurements were optimized and applied to the germplasm. Fruit quality traits have been characterized in France, Italy, Tunisia and Turkey. Resistance to pest and disease has been characterized on a part of the gene-pool against sharka, Monilia and Capnodis tenebrionis.

Abstract
Under the frame of an EEC - INCO-DC programme, 'APRIMED' research project is under development with the objective to characterize, to preserve and to identify the apricot genetic resources in part of the Mediterranean Region (Turkey, Spain, Italy, France, Morocco and Tunisia). An integrated and multidisciplinary approach divided in 3 main tasks has been developed. Prospection and preservation of genetic resources - During the prospection, 103 accessions have been identified in Morocco and 58 in Tunisia; while the preservation of 430 clones has been performed in France, 279 in Italy and 94 in Turkey. Characterization - A phenotypic characterization under UPOV descriptor has been achieved on 204 clones. A molecular characterization has been applied onto a set of 83 accessions by means of 4 microsatellites. Assessment of agronomic performances - The agronomic value has been accessed onto a total of 242 clones and partly investigated on 158 clones - Flower fertility has been investigated on the productive clones. Male sterility and interincompatibility groups have been identified. Chilling requirements and Floral anomalies measurements were optimized and applied to the germplasm. Fruit quality traits have been characterized in France, Italy, Tunisia and Turkey. Resistance to pest and disease has been characterized on a part of the gene-pool against sharka, Monilia and Capnodis tenebrionis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
