Promising Fig (Ficus carica L.) Genetic Resources from Birecik (Ur-fa) Region of Turkey

摘要

This study was aimed to select valuable genetic resources of fig in Birecik (Urfa) situated on the Southeast part of Turkey during 1998 and 1999. Populations consisting of native fig genotypes were examined in terms of fruit, leaf and tree characteristics, and 35 genotypes were selected for future breeding efforts. Their leaves and desirable fruit characteristics were determined by comparing with 'Bursa Siyahi', which has prime importance among table fig varieties in Turkey for fresh market. Some selections produced larger fruits than 'Bursa Siyahi'. All genotypes showed a range of 23 to 84 g in fruit weight, 36 to 56 mm in fruit width, 30 to 56 mm in fruit length and 0.08 to 0.2 mm in peel thickness. While total soluble solid contents ranged from 12 to 21.3 %, titratable acidity changed from 0.1 to 0.4 %. In addition, all types were investigated in terms of fruit shape index, skin colour, internal colour, peel thickness, skin cracks, ribs of peel, ease of peefing, number of leaves per shoot, leafdimensions, lobes, hairs, venation, presence of teeth, growth habit of tree and seasonal shoot growth. Many genotypes were evaluated as promising for further breeding efforts.
