In order to achieve greater food security, potato has played a major role in human food chains and achieving maximum yield along with other desirable components can be evaluated by stability and adaptation of diverse genotypes in different regions of our country. In this study, stability and adaptation of new genotypes of potato were evaluated that comprise 10 new early and medium maturity genotypes (Anabella, Taurus, Carrera, Liseta, Volumia, Colomba, crisps4all, Innovator, Leonardo and Sylvana) plus one control of medium maturity genotypes (Sante) and then they were planted in three different regions (Mashhad, Hamedan and Zanjan). All experiments were done in RCBD with three replications in two years (2016-2017). Moreover, they were planted in the fields of private section. Analysis of variance (ANOVA) results of early - medium maturity genotypes were investigated in different locations, genotype and genotype in year were significant for every single trait. The effects of year, location in year, and genotype in location were revealed by the results of combined analysis that only showed significant difference for traits of total tube yield, marketable tuber yield, and tuber seed number in plant. Among the medium and early maturity genotypes, the Liseta, Leonardo, Sylvana, Colomba and Carrera genotypes according to high tuber yield (4.66 to 5.03 kg.m-2) are introduced but Colomba, Liseta, and Carrera genotypes (5.03, 4.90 and 4.74 kg.m-2) with highest tuber yield and Anabella genotype with 4.25 kg.m-2 yield had highest adaptation for Zanjan and Mashhad regions respectively and also Sante genotype with 4.53 kg.m-2 yield for Hamedan. The Crisp4all, Innovator, and Taurus genotypes with the aim of consuming in the industrial sector (Chips and French fries) are introduced in particular with respect to high dry matter percentage (23.88, 21.91 and 21.24 % respectively).
