Host status of some broad bean, Vicia faba L., selections to reniform nematode, Rotylenchulus reniformis, under greenhouse conditions in Egypt
Archives of Phytopathology and Plant Protection 46 (20), 2486-2491
Abstract: Twenty broad bean selections were screened for their relative susceptibility to the reniform nematode, Rotylenchulus reniformis, under greenhouse conditions at 20 ± 5 °C. The degree of susceptibility was rated based on number of females per root system of each selection. Hence, G 3, L 47, L 49, L 52, L 57, L 71, L 92, L 99 and L 375 selections were graded as resistant hosts against the nematode infection and sex selections (G 429, L 13, L 16, L 24, L 31 and L 46) were categorised as moderately resistant. However, only the selection L 9 out of 20 selections was ranked as susceptible and four selections, namely L 50, L 101, L 241 and L 348, were rated as highly susceptible against R. reniformis infection. It was observed that reproduction of the nematode was favoured on highly susceptible and susceptible selections but inhibited on resistant ones. Therefore, all tested selections showed great variability in their reaction to the nematode infection according to the host type. Also, various plant growth parameters were discussed. Finally, the differences among the tested selections should serve as an informative resource for plant breeders and cropping systems to limit the loss due to the nematode infection.
