Eight spring canola cultivars (Brassica napus L. cvs. Marinka, Briol, Pactol, Helios, Star, Prota, Spok and Semu 209/82) were studied in field experiments for their responses to toxic B application at Central Anatolia, Turkey during the 2002 and 2003 growing seasons. The canola cultivars were grown under B moderate deficiency (extractable B 0.56 mg kg-1) and toxic B applied (15 kg B ha-1) conditions. In this study, oil yield and protein yield were investigated. According to the results, oil yield and protein yield varied significantly among the cultivars and B application decreased the oil yield and protein yield by 37.5 % and 38.6 % on average, respectively. Among canola cultivars, Briol, Marinka, and Spok were the most sensitive to B toxicity applications that had the highest oil yield and protein yield decrease when treated with B. On the other hand, Star and Pactol cultivars showed tolerance to B toxicity applications.
