Abstract

The aim of this study was to evaluate the agronomic performance and oil content of 13 canola genotypes in Western Paraná, Brazil. The experiment was carried out, during the year of 2015, in the municipality of Marechal Cândido Rôndon in the west of the State of Paraná. A Randomized Complete Block Design (RCBD) was utilized with four replications. The genotypes of canola evaluated were Hyola 401, Hyola 76, Hyola 61, Hyola 433, Hyola 50, Hyola 571CL, Hyola 575CL, Hyola 474CL, Hyola 555TT, Hyola 656TT, Hyola 559TT, W8006, and H92002. Sowing was done in plots with four rows, spaced at 0.45 and 5 m in length, on May 8, 2015. The evaluated parameter were phenology, plant height, number of pods per plant, grains per pod, weight of thousand grains, grain yield and oil content. Significant differences were observed where the genotype of canola Hyola 401 and Hyola 559TT reached the physiological maturation in 129 days. No significant differences were observed in the variables analyzed by the Tukey test at 5% probability except the mass of thousand grains in which the Hyola 76 genotype performed better, with 4.11 grams. The average grain yield of tested genotypes was 1518.14 kg ha-1 and the average of grain oil content was 42.45%.
