Abstract: This paper researched the agronomic traits, seed quality traits and lodging resistance of eight quinoa germplasm lines in Harbin, Heilongjiang Province. All the eight tested lines matured normally, with the growth period ranging from 112 to 121 days. The plant height ranged from 133.2 to 173.1 cm, the number of branches per plant was 18.1-23.1, the effective branching rate was 64.34%-72.87%, and the highest yield among the quinoa lines at Harbin was 2966 kg·ha-1. The ranges for protein, starch, and fat contents were, respectively, 13.74%-14.50%, 42.15%-60.11%, and 4.26%-6.74%, and the range for ash was 3.94%-6.46%. The lodging rate was between 9.00%-13.67%. Based on comprehensive consideration of evaluated yield and seed quality traits, the germplasm line LM-3 had the best performance, and production potential. This material is therefore recommended as suitable to be planted more widely in the Harbin region.
