Determination of performance of some promising potato (Solanum tuberosum L.) clones and registered varieties in high-altitude conditions

This study was conducted on Tokat/Artova conditions to identify the efficiency and quality elements between some commercial potato varieties and clones with super features. A total of 20 genotypes, 5 registered varieties and 15 promising clones, were used in the study. The study was conducted with 3 repetitions according to Randomized Blocks Design. Within the scope of this study; output time, output ratio, rachis number, plant height, ripening time, tuber yield per hill, average tuber weight, tuber yield, scattering of the tuber size, marketable tuber ratio, dry matter ratio, starch ratio and tuber internal blackening characteristics were examined. In accordance with the findings obtained; all the following values ranged between the mentioned spans; output time 26-40 days, output ratios 38-94%, rachis number 1.13-2.90, tuber yield per hill 3.22-12.86, average tuber weight 47.74-170.6g, tuber yield 744.1-4930.6 kg, marketable tuber ratio 74.47-85.47%, dry matter ratio 22.67-27.32, starch ratio 17.97-23.13%. Clones with high tuber yield in this study, respectively, were the clones with the code of PAİ 8.1.6 (4930.6kg) PAİ 8.8.57 (4695.7kg), GOÜ 6/28 (4661.7kg), PAİ 8.5.34 (4431.8kg), PAİ 8.7.49 (4245.1kg), PAİ 8.12.86 (4115.2 kg), GOÜ 10/15 (4071.3 kg). Among the varieties included in the standards, Algeria was the registered variety with the highest tuber yield, which was 4434.7kg.
