Abstract

Quinoa (Chenopodium quinoa Willd.), native to the South American Andes, has been adapted for cultivation in Brazil, via progeny selection. Originating from the Q4 population, from Ecuadorian valleys, Q4.5 has shown outstanding performance. During the trials, it was standardized for agronomic traits and named BRS Syetetuba. In the summer and winter, it reached 2.3 t ha-1 and 7.5 t ha-1, respectively for grain and biomass yield, in 120 days, from emergence to maturity. These results were higher than those reached by the BRS Piabiru and Kancolla check cultivars. The grains are saponin-free and have a mean weight of 2.9 g 1000-1. The results reveal that the BRS Syetetuba meets the desirable characteristics for commercial yield in Brazil.

KEY-WORDS: Chenopodium quinoa; grain weight; biomass; plant height.
