The effects on yield and components of yield in oats infected with BYDV-PAV at different growth stages
Bisnieks M, Persson T, Eckersten H, Sigvald RAbstract
The effects of a PAV isolate of barley yellow dwarf virus inoculated to oats at four different growth stages were evaluated in a field trial in Sweden. Oats (cv. Stork) were artificially infested with bird cherry-oat aphids (Rhopalosiphum padi) carrying a local Swedish PAV-Sto isolate. Infection, especially in early growth stages, decreased yield of grain biomass and plant height, but increased the number of tillers and panicles per plant, compared to uninfected plants. There was no effect on 1000-kernel weight and grain volume weight. The results emphasize the importance of barley yellow dwarf virus infection, especially at early growth stages in affecting oat yieldsPublished in
