Screening resistance level of Brassicaceae plants to cabbage cyst nematode, Heterodera cruciferae Franklin, 1945 (Tylenchida: Heteroderidae)

Although cabbage cyst nematode is one of the most common pests in the cabbage growing areas of Samsun, there were no records related to resistance of cabbages. The aim of this research was to screen cabbage cultivars resistance level for their potential to be included in breeding programs for resistance against Heterodera cruciferae. Franklin, 1945 (Tylenchida: Heteroderidae) Thirty cabbage cultivars were tested in controlled greenhouse trials and 3 cultivars were determined susceptible, 11 cultivars were partially susceptible, 9 cultivars were resistant and 7 cultivars were highly resistant. White head cabbage cultivars were the most resistant; 7 of them were highly resistant and 5 of them were resistant. Forty % of kale were resistant and 60% were partially susceptible. Chinese cabbage and Brussels sprouts were all classified as partially susceptible.
