ABSTRACT

The root system architecture of potato plants can play a key role in breeding new cultivars with higher drought tolerance. The purpose of this work was to assess the variability of the root systems of selected potato cultivars in the periods of highest sensitivity to drought. The plants of fifteen cultivars from different maturity classes were tested by using aeroponics. The study of the aboveground part of plants, tuber formation and the root system features was conducted at the early stage of tuberization. The results of the experiment were analyzed using ANOVA. Means were separated with Tukey’s contrast analysis at significance level 0.05. Significant differences among maturity class of cultivars in terms of length of stems, fresh matter of the above-ground part of plants, rooting depth, and fresh and dry matter of roots were found. The root system differences between genotypes were related to maturity class. At the early stage of tuberization very early cultivars were characterized by shallower rooting depth and less fresh and dry matter of roots than early and medium early cultivars. It was found that cultivars Tetyda and Finezja are cultivars of special beneficial traits of the root system.

Key words: drought stress, potato, rooting depth, Solanum tuberosum, tuberization.
