The study analyzed the behavior of some rapeseed genotypes, in comparative crops within ARDS Lovrin, Timis County, Romania. Nineteen genotypes were cultivated, in chernozem soil conditions, non-irrigated crop system, agricultural year 2022-2023. The yield (Y) varied between 1,288.24 kg ha^-1(Absolute genotype, RCH19 trial code) and 3,703.70 kg ha^-1 (Excited genotype, RCH2 trial code). The hectoliter weight (HW) varied between 51.60 kg hl^-1 (Immortal genotype, RCH5 trial code), and 75.00 kg hl^-1 (Excited genotype, RCH2 trial code). The weight of one thousand seeds (WTS) varied between 3.70 g (Ultimo genotype, RCH17 trial code), and 6.00 g (Umberto genotype, RCH11 trial code). Compared to the mean of the experiment (M_Exp = 2,347.65 kg ha^-1), the following genotypes stood out: Excited (RCH2) with Y = 1,356.05 kg ha^-1, Expectation (RCH3) and P314 (RCH9) with Y = 1,195.02 kg ha^-1, respectively Momento (RCH14) with Y = 1,033.99 kg ha^-1. In the case of the hectoliter weight (HW), compared to the mean of the experiment (HW = 62.51 kg hl^-1), the Excited genotype (HW = 75.00 kg hl^-1) was highlighted, followed by the Vito genotype (HW = 70.50 kg hl^-1). In relation to parameters Y, HW and WTS, PC1 explained 53.155% of variance, and PC2 explained 26.458% of variance.
