Sweet potato (Ipomoea batatas L.) cultivation in Turkey is concentrated in one province situated in Mediterranean region only, which would not fulfill the domestic needs of the country soon. Therefore, cultivation of the crop in other provinces/climatic regions should be initiated to fulfill the domestic needs. The cultivation in other provinces requires thorough assessment of yield and quality traits of target crop. Therefore, yield and quality characteristics of four sweet potato genotypes (i.e., 'Hatay Kırmızısı', 'Hatay Yerlisi', 'Havuc' and 'Kalem') were assessed in the current study in Kazova and Niksar counties of Tokat province of the country having middle Black Sea climate in field experiments during 2018 and 2019. The cuttings of the genotypes were planted in Niksar during the second fortnight of April and first week of May in Kazova. The planting density was kept 90 × 45 cm. Data relating to number of storage roots, storage root weight, storage root yield per hill and storage root yield per hectare were recorded. Furthermore, quality traits, including dry matter ratio (%), protein ratio (%) and antioxidant ratio (%) of storage roots were also determined. The highest total storage root yield was recorded for 'Havuc' genotype during both years and locations, followed by 'Hatay Yerlisi' and 'Hatay Kırmızısı' genotypes. Overall, storage root yield (60.06 and 62.40 tons ha-1 during first and second year) recorded for the experiment at Niksar was higher than the storage root yield recorded for Kazova experiment (53.50 and 52.84 tons ha-1 during first and second year, respectively). The highest dry matter was produced by 'Kalem' and 'Hatay Yerlisi' genotypes during both years and at both locations, followed by 'Hatay Kırmızısı' and 'Havuc' genotypes. The storage roots of the tested genotypes accumulated higher dry matter at Kazova during both years. The highest protein content was obtained from the 'Kalem' genotype, and the protein contents of the 'Hatay Yerlisi' and 'Hatay Kırmızısı' genotypes were close to the 'Kalem' genotype. The results indicated that tested genotypes can successfully be cultivated in middle Black Sea climate. Therefore, production of sweet potato can be initiated in the future to meet the domestic needs for sweet potato in the country.

土耳其黑海中部地区甘薯（Ipomoea batatas L.）基因型的产量和品质性状评估。


土耳其的甘薯（Ipomoea batatas L.）种植仅集中在地中海地区的一个省份，短期内无法满足该国的国内需求。因此，应开始在其他省份/气候区种植该作物以满足国内需求。外省种植需要对目标作物的产量和品质性状进行全面评估。因此，本研究在该国托卡特省卡佐瓦县和尼克萨尔县评估了四种甘薯基因型（即“Hatay Kırmızısı”、“Hatay Yerlisi”、“Havuc”和“Kalem”）的产量和品质特征。 2018 年和 2019 年期间，在黑海中部气候的田间实验中进行了试验。基因型的插条于 4 月的第二个星期和 5 月的第一周在卡佐瓦 (Kazova) 的尼克萨尔 (Niksar) 种植。种植密度保持90×45厘米。记录与贮藏根数量、贮藏根重量、每山贮藏根产量和每公顷贮藏根产量有关的数据。此外，还测定了贮藏根的干物质比率（%）、蛋白质比率（%）和抗氧化比率（%）等品质性状。在这两个年份和地点，“Havuc”基因型的贮藏根总产量最高，其次是“Hatay Yerlisi”和“Hatay Kırmızısı”基因型。总体而言，Niksar 实验记录的贮藏根产量（第一年和第二年分别为 60.06 和 62.40 吨 ha-1）高于 Kazova 实验记录的贮藏根产量（第一和第二年分别为 53.50 和 52.84 吨 ha-1，分别）。在这两年和两个地点，“Kalem”和“Hatay Yerlisi”基因型产生的干物质最高，其次是“Hatay Kırmızısı”和“Havuc”基因型。 在卡佐瓦，测试基因型的贮藏根在这两年中积累了较高的干物质。 'Kalem' 基因型的蛋白质含量最高，'Hatay Yerlisi' 和 'Hatay Kırmızısı' 基因型的蛋白质含量与 'Kalem' 基因型接近。结果表明，测试的基因型可以在黑海中部气候下成功培育。因此，今后可以启动红薯生产，以满足国内对红薯的需求。
