Quinoa (Chenopodium quinoa Willd.) is an alternative plant of which cultivation rapidly increases because of its high nutritive value. Background studies should be conducted on the determination of quinoa cultivars appropriate for different ecologies for its cultivation to become widespread in a healthy way. This study was planned to identify suitable quinoa cultivars in Erzurum and Iğdır provinces which demonstrate different ecological characteristics of the Eastern Anatolia Region. The study was conducted in 2015 and 2016 under irrigated conditions. The experiments were conducted with 10 genotypes in each location in a randomized complete blocks design with four replications. The grain yield and some related characteristics were examined in the study. The maturation time, grain yield and related characteristics of quinoa varied significantly depending on genotypes and locations in the study. The earliest and most productive genotype is Q-52 and it produced 979.8 kg ha-1 of seeds under Erzurum conditions and 3679.6 kg ha-1 of seeds under Iğdır conditions. According to the results of the study, quinoa is a risky product in Erzurum which has a high altitude. However, cultivars such as Q-52, Rainbow, Red Head and Mint Vanilla were found promising for Iğdır location.
