Abstract

As the result of several decades of traditional breeding on the resistance of wheat to viruses, foreign scientists have succeeded in identifying resistance sources (cultivar Geneva, Thinopyrum species) and resistance genes (Bdv1, Bdv2, Bdv3, Wsm1) that can be efficiently used against the cereal viruses attacking wheat, including Barley yellow dwarf viruses (BYDV), Cereal yellow dwarf viruses (CYDV), Wheat streak mosaic virus (WSMV) and Wheat spindle streak mosaic virus (WSSMV). Some of the lines carrying the translocation do not yet have a yield average as high as that of cultivated varieties, though the use of varieties and breeding lines carrying resistance genes is the most effective way of maintaining yield averages in the case of infection. Some lines contain a combination of several resistance genes, and these gene pyramids afford protection against a number of viruses. The mechanism of resistance is partly known (Bdv2), but in some cases further research will be required (cultivar Geneva). The advantage of using resistance sources in wheat has been recognised in Hungary, as elsewheres and it is hoped that they will soon spread on an increasingly wide scale.
