Turkey is one of the biggest chestnut producers in the world. Most of the chestnut trees found in forests in Turkey and the majority of them are coming from seeds showing huge phenotypic diversity. The study was conducted on naturally growing chestnut trees found in forests belongs to Artvin province located in the northeastern part of Turkey. A total of 22 promising chestnut genotypes previously selected among chestnut populations (Castanea sativa) in 2016 and morphological and biochemical data were collected during 2016 and 2017 harvest season. Morphological parameters were tree growth habit, nut weight, nut size, kernel ratio, and kernel color, respectively. Biochemical characteristics include moisture, crude protein, crude fat, dietary fiber, total carbohydrates, total polyphenols and antioxidant activity of kernels. Results clearly revealed that seed-propagated 22 chestnut genotypes have distinct properties. Average nut weight and kernel ratio varied from 4.38 to 9.19 g; 75.16 to 86.41%. The majority of genotypes were semi-upright growing habit. Total crude fat, crude protein and dietary fiber ranged from 0.87 to 2.61%; 4.80 to 7.65% and 2.06 to 3.61%, respectively. Results indicated that the Artvin region has valuable chestnut genetic resources.

土耳其是世界上最大的板栗生产国之一。在土耳其森林中发现的大多数栗树，其中大部分来自表现出巨大表型多样性的种子。该研究是在土耳其东北部阿尔特温省森林中发现的自然生长的栗树上进行的。先前在板栗种群中筛选出的共有 22 个有前景的板栗基因型 ( Castanea sativa) 在 2016 年和 2016 年和 2017 年收获季节期间收集了形态和生化数据。形态参数分别为树木生长习性、坚果重量、坚果大小、仁比和仁颜色。生化特性包括水分、粗蛋白、粗脂肪、膳食纤维、总碳水化合物、总多酚和籽粒的抗氧化活性。结果清楚地表明，种子繁殖的 22 种栗子基因型具有不同的特性。平均坚果重量和仁比从 4.38 到 9.19 克不等；75.16 至 86.41%。大多数基因型为半直立生长习性。总粗脂肪、粗蛋白和膳食纤维为0.87%至2.61%；分别为 4.80 至 7.65% 和 2.06 至 3.61%。结果表明，Artvin 地区具有宝贵的板栗遗传资源。
