The Reaction of Cabbage (Brassica Oleracea L.) Breeding Lines Against Turnip Mosaic Virus

Abstract

Turnip mosaic virus (TuMV) is the most important and widespread virus infecting brassicas worldwide. In 2013, 2014, and 2015, twenty-three cabbage (Brassica oleracea L.) breeding lines from Black Sea Agricultural Research Institute (BSARI, Samsun, Turkey) were screened for their reaction to TuMV-BA isolate by mechanical inoculation under controlled conditions. On the basis of 0–5 disease rating scale and ELISA, of the lines tested, nine (39.1%) were categorized as highly resistant (Grade 1), one (4.3%) as resistant (Grade 2), seven (30.4%) as moderately resistant (Grade 3), however, two cabbage lines and four lines were found moderately susceptible and susceptible, respectively to TuMV-BA isolate under controlled conditions. The results suggested that Brassica oleracea L. from the BSARI contain valuable breeding lines resistant to TuMV, and the screened breeding lines in the current study could provide promising resistance sources for cabbage breeding. © Wydawnictwo Uniwersytetu Przyrodniczego w Lublinie, Lublin 2016.
