Abstract: In order to study adaptive performance of quinoa varieties in the Linxia arid region of Gansu province, we tested 13 different quinoa varieties (designated CK, Q1 to Q12), to determine seedling emergence rate, phenology, botanical characters, yield, quality and disease resistance. Cluster analysis was applied to evaluate the relationships among selected traits. It was found that all 13 quinoa varieties are able to reach maturity in the test region. There were significant differences among varieties for plant height, branching index, effective branching rate, inflorescence spike length, inflorescence spike diameter, thousand kernel weight, and crude protein and crude fiber content. In addition, cluster analysis revealed Q7 and Q8 are dwarf early varieties, while varieties Q1, Q7, Q8, Q9, Q10 show disease resistance. Q9 is high yielding (4247 kg/ha, 1252 kg/ha higher than control). There were no phenology characters of obvious relevance to variety choice. Considering all factors measured, Q9 had the best all round performance and could potentially be planted more widely as a crop in the Linxia arid region of Gansu province.
