Brassica nigra, and B. juncea, are two economically important species that are used as spices; and B. juncea, B. rapa ssp., oleifera, and B. nigra are used for industrial seed oil. The potential of 16 Brassica genotypes’s comparison with 2 standard varieties was done in terms of their phenology, morphology, and yield performance under autumn-sown conditions during 2019-20 and 2020-21 under semi-arid climatic conditions of Central Anatolia, in Ankara, Türkiye. The experiment was performed in a randomized completeblock design with four replications. The results indicated statistically significant genotypes x years interaction among all genotypes for plant height, number of branches, number of pods, number of seeds, 1000-seed weight, seed yield, and crude oil yield of Brassica spp. Seed emergence, rosette formation stage, 50% flowering, and 50% pod formation of Brassica spp. varied according to species and years. While the maximum and minimum crude oil yields of 1222 kg ha-1 were obtained from Standard 2 (B. napus-Excalibur) and 313 kg ha-1 from the Bn4 genotype; the Br2 (1123 kg ha-1), Br3 (1042 kg ha-1), Br6 (1093 kg ha-1), Br5 (949 kg ha-1) B. rapa ssp., oleifera and Bj3 (893.3 kg ha-1) B. juncea genotypes appeared superior in performance compared with the other genotypes. These genotypes can be further exploited in various improvement programs through selection and hybridization.
