Conteúdo:	Canola (Brassica napus L. var. oleifera) is a major oilseed crop for human consumption and biodiesel production, yet its agronomic performance and seed quality under high-altitude tropical conditions are not well documented. This study evaluated four canola cultivars (Alth B4, Diamond, Hyola 575 CL®, and Nuola 300) grown at an altitude of 1,387 m above sea level in the Brazilian Cerrado, a savanna area in Diamantina, Minas Gerais, Brazil. The experiment followed a completely randomized design with four replications, assessing plant growth, productivity, seed physiological quality, and oil content. The phenological cycle of the cultivars ranged from 140 to 146 days. Productivity was highest for Nuola 300 and Alth B4 (~2,034 kg ha-¹), exceeding the national average, while Diamond and Alth B4 exhibited superior seed vigor and germination performance. Oil content varied from 42.57% to 46.36%, with Alth B4 and Diamond showing the highest values. Principal component analysis highlighted strong associations between agronomic performance and seed quality, distinguishing Diamond, Nuola 300, and Alth B4 as the most adaptable to high-altitude savanna conditions, while Hyola 575 showed lower overall performance. These findings demonstrate that canola can achieve high productivity and seed quality in high-altitude Cerrado regions, identifying cultivars with strong potential for commercial cultivation in these conditions.
