Abstract :In variety development studies through hybridization, it is necessary to make hybridization with the parents suitable for the purpose, to obtain the tubers in seedling generation from the hybrid seeds obtained, and then to proceed to the clonal selection process. In this study, it was aimed to select clones suitable for tuber shape, earliness, table and industrial use in different locations in the first clonal generation stage from the variation created by hybridization between some commercially registered potato varieties, local potato varieties and some clones with superior characteristics. The study was conducted with 3316 clones in Artova and Kazova districts in Tokat province in Turkey. In this year, which was the first clonal selection stage, besides phenotypic characteristics such as breeder`s preference, maturity group, tuber defects, skin roughness, skin and tuber flesh color, characteristics such as the number of tubers per hill, tuber yield per hill, average tuber weight, depth of lateral insert ignore into journalissuearticles values(eye); and apical buds were examined and data on clones belonging to each hybrid family were obtained. Thus, it was decided to proceed to the next selection stage with 918 clones selected due to their compliance with the criteria determined in the first clonal generation stage.
