Controlling fusarium head blight of wheat (triticum aestivum L.) with genetics

Abstract

Fusarium head blight, one of the most destructive diseases of wheat (Triticum aestivum L.), results in significant economic losses from reduced grain yield and quality. In recent decades, the disease has been frequently recorded, especially under warm and wet climatic conditions. Genetic resistance has engaged plant breeders because the use of resistant cultivars is the most economical, effective, and environmentally friendly method of control. In the present paper, we summarize the research on resistance genetics of Fusarium head blight, suggest a new method for evaluating Fusarium head blight resistance, and recommend strategies for creating and developing new sources of resistance to Fusarium head blight through the use of alien genes and chromosomal segments.

Performance Indices in Wheat Chlorophyll a Fluorescence and Protein Quality Influenced by FHB

“…Statistically significant differences were found in the F v /F m and PI parameters among all tested varieties at different measurement times, and ‘Vulkan’ was different from the two other varieties, with the lowest PI and F v /F m values. This varietal difference could be explained by the genetic basis of photosynthetic traits within varieties [ 28 ] as well as the variation in leaf senescence induction, which occurs later [ 14 ] and may also diminish photosynthetic performance. However, ‘Vulkan’, in comparison to ‘Golubica’ and ‘Kraljica’, was less affected by FHB infection in terms of disease symptoms.…”

“…The PI and F v /F m values indicate a lower photosynthetic performance at first measurement in both treatments in all three varieties, but the values of PI and F v /F m increased until 4 days after inoculation. At 7 days after inoculation, generally, significant decreases in those parameters were observed in all three varieties in both treatments (except PI for ‘Kraljica’ in the control group), suggesting a downregulation of photosystem II, which may indicate an initiation of leaf senescence [ 14 , 28 ]. Additionally, an induction of grain filling and an onset of senescence in wheat are concurring processes.…”

“…FHB can cause grain quality reduction as a result of contamination by trichothecene mycotoxins produced by Fusarium species [ 14 ]. Wheat gluten proteins are very important because they are related to many processing properties.…”

“…FHB outbreaks have become more serious and more frequent in recent decades, possibly due to climate change and agronomic practices (especially maize–wheat rotations). Globally, FHB causes about 10–70% yield loss in epidemic years ( Zhang et al, 2011 ). In the Middle-Lower Yangtze River Valley Region of China, FHB causes 5–10% yield loss in most years but can cause losses of nearly 100% in severe epidemic years ( Cheng et al, 2012 ).…”

“…Фузаріоз не лише зменшує урожай, а й робить його непридатним для вживання людиною та тваринами через накопичення у зерні токсинів. Стійких до фузаріозу сортів пшениці поки немає [3,4]. Серед дикорослих родичів пшениці стійкість зареєстрована для декількох родів, які не мають з пшеницею гомологічних геномів (Roegneria, Hystrix, Elymus, Kengyilia, Agropyron, Thinopyrum) або мають геноми, гомологічні субгеномам пшениці м'якої, А, В та D (диплоїдні та дикорослі тетраплоїдні пшениці, індуковані мутанти T. durum, види роду Aegilops) [2,[5][6][7].…”
