Description
Summary:The common fig tree (Ficus carica L.) is a Mediterranean crop with problematic cultivar identification. The recovery and conservation of possible local varieties for ecological production requires the previous genetic characterization of the available germplasm. In this context, 42 lines corresponding to 12 local varieties and two caprifigs, in addition to 15 reference samples have been fingerprinted using 21 SSR markers. A total of 77 alleles were revealed, detecting a useful level of genetic variability within the local germplasm pools. UPGMA clustering analysis has revealed the genetic structure and relationships among the local and reference germplasm. Eleven of the local varieties could be identified and defined as obtained clusters, showing that SSR analysis is an efficient method to evaluate the Andalusian fig tree diversity for on‐farm conservation.
