Özet

This experiment was carried out in three different locations with different environmental characteristics such as altitude, soil structure and precipitation in the Central Black Sea Region in Turkey between 2017-2018. The aim of this study was to investigate performance, dry matter ratio and total tuber yield of 15 different promising potato clones and five different potato commercial cultivars in various environments. The average tuber yields across the environments was 32.44 ton/ha while the average of standard cultivars was 35.13 ton/ha and average of advanced clones was 31.54 ton/ha. The mean dry matter ratio was 19.64%, which was 20.22% for commercial varieties and 20.03% for advanced clones. In terms of the stability and genotype ? environment interaction for tuber yield, regression coefficients varied from ?i = 0.10 to 3.39. PAI-8-857, PAI-8-3-15, PAI-8-6-35 and PAI-8-5-34 were closest to ?i = 1 in all environments in respect of the general average and regression coefficient. PAI-8-857 and GOU 6/28 were better suited to grow in all environments. The dry matter values were also subjected to stability and genotype ? interaction analyses. The regression coefficients varied from ?i = 0.06 to 2.76. PAI-8-8-57 clone had higher dry matter content than other genotypes under suitable conditions.
