Assessment of genetic diversity of thirty Tunisian fig (Ficus carica L.) accessions using pomological traits and SSR markers
Sixteen pomological traits were employed to characterize the diversity of 30 fig accessions collected mainly from Southeastern Tunisia and maintained at CFPA 'El Gordhab', Tataouine, in Southeastern Tunisia. Additionally, 13 simple sequence repeat (SSR) loci were analyzed to detect the gen...

| Sumario: | Sixteen pomological traits were employed to characterize the diversity of 30 fig accessions collected mainly from Southeastern Tunisia and maintained at CFPA 'El Gordhab', Tataouine, in Southeastern Tunisia. Additionally, 13 simple sequence repeat (SSR) loci were analyzed to detect the genetic diversity of the 30 fig accessions. In this study, qualitative data (fruit shape, fruit external color, fruit internal color, abscission of the stalk from the twig, skin peeling, fruit skin firmness) showed morphological variation within accessions. A highly significant difference (p < .01) among accessions was revealed for all the quantitative traits. The first three components (PC1, PC2, and PC3) of PCA accounted for 52.99% of the total variability. PC1, PC2, and PC3 accounted respectively for 28.02, 13.05, and 11.91% of the total variance. The most discriminating morphological parameters were fruit length and diameter, stalk length and diameter, neck length and diameter, stalk and flesh thickness, fruit shape, skin p |
