In order to investigate the relationships among the traits of Chenopodium quinoa, a split plot factorial experiment based on randomized complete block design with three replications was conducted at Imam Khomeini International University Research Station in Qazvin. Irrigation was applied as main factor in three levels of 6, 8 and 10 days once in main plot and fertilizer factor in two levels of consumption as 100% fertilizer recommendation and 50% fertilizer recommendation and cultivar factor including Giza, Red Carina and Titicaca was applied to the sub plots as factorial. In this experiment, leaf relative water content, chlorophyll content, stem diameter, height, number of fertile branches, biomass, 1000-grain weight, and grain yield were measured. The results of correlation analysis showed a significant positive correlation between grain yield and stem diameter, number of fertile branches and biomass. Results of stepwise regression analysis and path coefficients analysis showed that biomass and number of fertile shoots had the most effect on grain yield among studied traits. Therefore, grain yield can be improved by improving these traits.
