| Abstract:
An important cultivar variablity exist in fig Ficus carica L. cultiveted in many region of north Morroco. Prospection and collect of fig material has been conducted by INRA. The aim is to charaterize the morphological and pomological traits and propose a genetic knowledge base necessary for the selection of performing genotypes. 16 characters concerning tree and fruit were measured on 45 local genotypes using the descriptors established by the European project “Minor Fruit Tree Species Conservation” RES GEN 29. Results have shown a large diversity in forms, fruits shape, skin colors, fruit weight ostiole size and in fig internal quality. Multivariate analysis (AFC) of traits has shown that the five first axes accounted for 76% of total variance. Axis 1 manly explained by weight, axis 2 by ostiol size and fissures and axis 3 by fig cavity trait. Each of 45 cultivars was separated and represented a defined genotype. These results shows that the collection presents a large genetic variability. | |
