The effects of barley yellow dwarf virus on the development, grain yield and yield components of oat cultivar Veli and breeding lines Hankkija 78152 and 78033 were studied in two years. Cultivar differences to BYDV infection were best observed at a low infection level. Single tiller analysis indicated close correlation between symptom severity and reduction in main yield components. Early infection caused greatest yield losses in all cultivars. BYDV strongly reduced both plant height and harvest index. Mild infection reduced the grain yield by 2—8 %, but severe infection by 36—41 %. The number of grains and panicle weight were strongly reduced, but the 1000-grain weight was only slightly affected after severe BYDV-infection. Implications of these results for disease control are discussed.

Yellow Dwarf Virus

Barley Yellow Dwarf Virus is a Luteovirus disease that affects small grain yields. The climatic conditions of the agricultural year favoured the development of vectors, so that the virus attack caused significant damage on different genotypes. The first visible symptom includes plant stunting and yellowing and purpling, so that plant height was the first traits affected reducing with 24.58 to 44.33 % compared to the unaffected plants. Regarding the main yield components their performance or reduced with 37.89 % to 74.35 % for weight of spike, 33.66 to 87.70% for number of grains per spike and from 50.90 to 88.03 % in case of weight of grains per spike. Grain yield as a complex and most important feature that characterizes a genotype was affected between 49.05 to 87.76 % which suggest that the infection can have a different intensity depending on certain morpho-physiological traits.
