Özet

Both the wheat species Triticum aestivum L. and Triticum durum Desf., which have wheat cultivars that are most important for small grain field crops, are grown worldwide as food sources for a rapidly increasing world population. Because of recent global climate changes, pathogenic diseases, pests, and abiotic stress factors on wheat crops have become more detrimental than ever before. Increases in atmospheric temperature have stimulated drought stress as well as having caused increased vector-borne viruses and other systemic disease pathogens. Another influence caused by ongoing global climate change is that sporadic local virus diseases are becoming more widespread by vector-borne transmissions. Wheat cultivars are naturally found susceptible to at least 30 virus diseases under field conditions. However, five of those viruses, namely, yellow dwarf viruses (YDVs), wheat streak mosaic virus (WSMV), wheat dwarf virus (WDV), soilborne wheat mosaic virus (SBWMV), and wheat spindle streak mosaic virus (WSSMV), occur in all wheat-growing areas of the world and cause substantial grain yield losses. Thus, this chapter will examine host range and disease incidence geographically in the world, disease symptoms, the morphological and molecular structure of viruses, and the annual disease cycle. It will also review disease management. In conclusion, the impact of these wheat virus diseases on food security is evaluated in this chapter. © Springer Nature Singapore Pte Ltd. 2024.
