Resumo

The consumption of quinoa is growing in the world because of its high nutritional value and genetic variability, but is still required further study on its development in Brazil. This work aimed to characterize the development of 16 genotypes of Chenopodium quinoa grown in the western region of Paraná. Two experiments were conducted in the period of September to December 2014 and October 2014 to January 2015. The parameters evaluated were: number of days to flowering, plant height at flowering, cycle, plant height at maturity, height insertion of the first inflorescence, plant population, productivity, saponin content and moisture content. Plant height at flowering ranged from 0.75 to 1.09 m, and 0.80 to 0.91m in the experiments, respectively. In the first experiment the Q13-17 genotype with higher productivity, only took 46.57 days after sowing to flower, and time below the eleven genotypes. All genotypes are considered bitter, presented early cycle and height of the first inflorescence enough to allow mechanized harvesting. The genotypes Q13-17, Q13-21, Q13-04 and Q12-23 showed productive potential to continue to be evaluated in order to select cultivars adapted to the environmental conditions of the Western Region of Paraná.
