The correlation coefficients between these traits were calculated using SAS program. Fruit weight, fruit diameter, fruit length, neck length, ostiolium width, abscission of the stalk from the twig, ease of peeling, fruit skin cracks, thickness of the fruit skin, texture of skin, fruit ribs, fruit internal cavity, TSS （total soluble solids）, pH, acidity, TSS/acidity, trunk diameter, shoot length, yield per tree were traits examined in the study. According to five-year data, fruit weight was found to have positive correlation by fruit diameter （r = 0.92; P 〈 0.01）, fruit length （r = 0.81; P 〈 0.01）, neck length （r = 0.35; P 〈 0.01）, ostiolium width （r = 0.23; P 〈 0.01）, trunk diameter （r = 0.26; P 〈 0.01）, fruit skin cracks （r = 0.26; P 〈 0.01） and negative correlation by TSS （r = -0.26; P 〈 0.01） and fruit ribs （r = -0.21; P 〈 0.01）. Relations between some traits such as ostiolium width, abscission of the stalk from the twig, ease of peeling, fruit skin cracks, texture of skin and fruit ribs are deviated based on the years. Some relationships between fig fruit characteristics exist, which may help researchers to solve some problems such as ostiolium width and fruit skin cracking. These studies may contribute to producing fruit with a good quality and help to evaluate new cultivars.展开更多
