Quinoa (Chenopodium quinoa Willd.) is a plant that is commonly grown for its edible seeds but is also used as fodder. To study the relationship between 21 morphological traits of 70 quinoa genotypes, an experiment was conducted in the form of the randomized complete block design with three replications in the research farm of the faculty of agriculture of Shahed University. The results of multiple variance analysis showed a significant difference among the studied genotypes. The mean squares were significant for stem wet weight (SWW), number of leaves1 (54 days after seed sowing) (NL1), leaf dry weight (LDW), thousand-grain weight (TGW), number of leaves2 (harvest time) (NL2), plant height2 (harvest time) (PH2), and leaf chlorophyll content1 (54 days after seed sowing). The mean squares were significant for SWW, NL1, LDW, TGW, and PH2. The results of the mean comparison with Duncan's test showed that the G117 genotype had the highest SWW (33.35 g), NL1 (74.16) and the LDW (5.62 g). The highest TGW was estimated in genotype G83 with 2.70 g. The results of path analysis using raw data (with replications) were different from data with the mean data (mean of replications). In both cases, the panicle dry weight had the greatest direct effect on the grain dry weight and the plant dry weight. Due to the average traits associated with grain and leaf yield, the G117 genotype is introduced as the superior genotype.
