NOBRE DE ARAUJO, Lucas et al. Tropicalization of canola (Brassica napus L.): commercial hybrids show potential for cultivation in the Brazilian Cerrado. Rev. Fac. Cienc. Agrar., Univ. Nac. Cuyo [online]. 2021, vol.53, n.2, pp.20-26. ISSN 1853-8665.

Given its high energetic efficiency, canola (Brassica napus L.) constitutes a potential biodiesel feedstock. However, since this crop is native to temperate regions, Brazil has not yet consolidated its production. Thus, the objective of this study was to evaluate agro nomic performance of canola hybrids grown in the tropical Brazilian Cerrado (15° 35’18” S, 47° 43’57” W at 999 m), aiming to select promising candidates for crop expansion. Our hypothesis states that obtaining high canola yields in Cerrado conditions is possible given a favorable agronomic adaptation of the species to this environment. Eight commercial canola hybrids were evaluated for seven agronomic traits in three experiments. Data were subjected to joint ANOVA and Tukey test. Grain yield of the evaluated hybrids resulted higher than the national average, including southern plantations. Hyola 61 and Hyola 76 hybrids outperformed regarding grain yield, followed by Diamond which, in addition to high productivity, exhibited a short crop cycle, even in rainfed conditions. Given these char acteristics, Diamond hybrid can be considered the best option for crop rotation system. These promising results reveal the adaptability and cultivation potential of these hybrids in the Brazilian Cerrado.
