| description | The introduction of quinoa (Chenopodium quinoa Willd.) in the Brazilian savanna has been successful based on the selection of progeny from valley types. Given the wide variation of environments, an alternative to define the maturation cycle of the plant has been the use of accumulated thermal units (ATU). This measure allows prediction of the plant cycle and supports the definition of phenology duration useful in crop management and quinoa breeding. This study aimed at calculating the ATU for the 13 codes of the BBCH scale of quinoa by evaluating 12 selected progenies grown in two sowing dates, at 15° 56’ S and 47° 55’ W, altitude of 1.100 m, Brasilia, DF, Brazil. Statistical differences were predominant from the beginning of the BBCH-50 reproductive phases, classifying the progenies as early, mid-cycle and late. Early maturity progenies and respective ATU for BBCH-89 are BRQ4 (1.676,8), BRQ1 (1,685), and AUR (1,691), contrasting with late BLA (2.239), BRQ3 (1,929.1 GDD), and BRQ8 (1,895). The accumulated thermal units for BBCH-89 ranged from 1565.25 to 2381, with a difference between the earliest and latest genotypes of 815.75. Progenies selected from existing cultivars are different in thermal unit accumulation, ensuing efficiency in cultivar acquisition to stagger quinoa cultivation. Accumulated thermal units explain the range of plant maturity cycles in selection. Additionally, the calculation of atu for BBCH scale codes is an effective tool for predicting the phenological cycle of quinoa. |

La introducción de la quinua (Chenopodium quinoa Willd.) en la Sabana Brasileña ha tenido éxito basada en la selección de progenies de los tipos de valle. Dada la amplia variación de ambientes, una alternativa para definir el ciclo de madurez de la planta ha sido el uso del tiempo térmico acumulado (TTA). Esta medida permite la predicción del ciclo de la planta y proporciona apoyo para definir la duración de la fenología, siendo útil en el manejo y mejoramiento de los cultivos. Este estudio tuvo como objetivo calcular las unidades térmicas para 13 códigos de la escala BBCH de la quinua, mediante la evaluación de 12 progenies seleccionadas y cultivadas en dos fechas de siembra, a 15° 56' S y 47° 55' O, altitud de 1.100 m, Brasilia, DF, Brasil. Las diferencias estadísticas fueron predominantes desde el inicio de las fases reproductivas BBCH-50, clasificando las progenies como precoces, de ciclo medio y tardías. Las progenies de madurez temprana y sus respectivas TTA para BBCH-89 son BRQ4 (1.676,8), BRQ1 (1.685) y AUR (1.691), contrastando con las tardías BLA (2.239), BRQ3 (1.929,1 GDD) y BRQ8 (1.895). Las unidades térmicas acumuladas para BBCH-89 oscilaron entre 1.565,25 y 2.381, con una diferencia entre los genotipos más precoces y los más tardíos de 815,75. Las progenies seleccionadas de los cultivares existentes son diferentes en cuanto a la acumulación de unidades térmicas, lo que implica la eficiencia en la adquisición de cultivares para escalonar el cultivo de quinua. Las unidades térmicas acumuladas explican el rango de ciclos de maduración de las plantas en la selección. Además, el cálculo del TTA para los códigos de la escala BBCH es una herramienta eficaz para predecir el ciclo fenológico de la quinua.
