Abstract

The creation of some potato genotypes with a high genetic homeostasis could confer a greater ecological plasticity with an increased resistance to the attack of the pathogen agents, such that notable performances concerning the main quality features represent the objectives reached in the potato breeding laboratory from ARDS of Suceava. Taking into consideration the area offered by the institution, the climatic conditions are favorable to many diseases, knowing the contribution of the genotype to the attenuation of its limitative effects represented by a great preoccupation. Besides the mentioned aspects, some quality features have been taken into consideration, such as: the form of the tubers, the depth of the eyes, the skin suberization level, the color of the pulp which confers a commercial quality and of course the economic increase of the production. This work is part of a more vast thematic research, initiated with the purpose of creating new potato advanced cultivars through an increased production capacity. With good resistance to the biotic and abiotic stress factors, advanced cultivars with superior culinary qualities are suitable for industrialization. The quantity and quality features depend to a great extent on the genetic income of the partners, in such a way that these characters have been transmitted in pedigree and the recombination specific capacity. 

Key words: Advanced cultivars, potato lines, vegetation period.
