Turkey is a country with different geographical features and therefore it is extremely diverse in plant diversity. Tomato is one of the most important vegetables produced both in the world and in Turkey. In this study, it was aimed to determine the genetic diversity of 24 tomato genotypes collected from local farmers from "Center villages" and "Üzümlü" district in Erzincan province.
Morphological (qualitative and quantitative) and ISSR(Inter Simple Sequence Repeat)were used to determine genetic diversity among genotypes. Contribution rates of morphological properties to the first three main components differed. Genotype 24 was found to be higher than other genotypes with important quantitative morphological features such as fruit length, fruit width, fruit weight and soluble solid content (SSC). Considering the overall morphological traits, a wide variation was detected between genotypes. Genotypes were divided into 2 main groups according to the evaluation with molecular markers. According to the molecular findings obtained. The polymorphism rate ranged from 0 to 100% and the average polymorphism rate was calculated as 80%.
Present findings revealed the diversity in tomato genotypes collected from Erzincan province and may constitute the bases for further breeding studies in tomato and will bring an integrity in tomato identification studies.
土耳其是一个具有不同地理特征的国家，因此植物多样性极其丰富。番茄是世界上和土耳其最重要的蔬菜之一。本研究旨在从埃尔津詹省“中心村庄”和“Üzümlü”地区的当地农民那里收集的 24 个番茄基因型中确定遗传多样性。
使用形态学（定性和定量）和 ISSR（简单序列重复间）来确定基因型之间的遗传多样性。形态特征对前三个主要成分的贡献率不同。基因型 24 被发现具有重要的定量形态特征，如果实长度、果实宽度、果实重量和可溶性固形物含量（SSC），高于其他基因型。考虑到整体形态特征，在基因型之间检测到广泛的变化。根据分子标记的评估，将基因型分为 2 个主要组。根据获得的分子发现，多态性率范围为 0 到 100%，平均多态性率计算为 80%。
本研究揭示了从埃尔津詹省收集的番茄基因型的多样性，可为番茄进一步的育种研究奠定基础，并为番茄鉴定研究提供完整性。
