Legume-colonizing aphids as potential PNYDV-vectors: Reproduction and infestation dynamics in two different field bean varieties [Dataset]
(Universität Kassel) Berawe, Ahmed; Ziebell, Heiko; Seeger, Judith Nora; Saucke, Helmut
This data and corresponding manuscript partly demonstrates why the ‘GL Sunrise’ faba bean variety has exhibiting lower viral symptoms in the field despite lacking resistance to Pea necrotic yellow dwarf virus (PNYDV). The apparent field resistance to PNYDV in the faba bean cultivar ‘GL Sunrise’ is due to effects on aphid vectors that transmit the virus between plants. This research shows aphid reproduction on the ‘GL Sunrise’ variety was lower compared to the ‘Fuego’ variety. This work also shows the importance of conducting lab experiments to complement field work with relevant field-derived aphid strains. This research provides valuable insights into PNYDV occurrence in the field and informs the development of resistant varieties. This work also shows that varietal testing should include assays to test a range of aphid behaviours as well as growth and reproduction when evaluating new varieties.
