The level of intensity of soft winter wheat varieties infection by Fusarium link pathogens and their identification on grain

In today's environment, an important task of agricultural production is to increase yields and improve the quality products. A reliable environmentally beneficial factor for sustainable yield improvement grain development new varieties with group resistance diseases a high level adaptability. The effectiveness selection immunity directly depends on diversity donor genes, search sources has been remains urgent issue. aim study was determine infection soft winter wheat Fusarium head blight pathogens identify them. Varieties from different breeding institutions Ukraine were used in research: Institute Plant Industry named after V.Y. Yuriev NAAS (IPI), Physiology Genetics National Academy Sciences (IPPG), Protection (IPP), Irrigated Agriculture (IA), Research Center "Institute NAAS" (NRC IA). Phytopathological analysis species composition pathogen, proportion determined by ratio infected samples their total number. higher (15-18%) intensity observed Perfect, Turunchuk, Ovid, Vodograi, Mirolyubna. During years research, colonized following ear blight: F. sporotrichiella, monilifopme, graminearum, culmorum, avenaceum, gibbosum sambucinum oxysporium. monilifopme oxysporium dominated, prevalence 16.2 1.7% grain, respectively. lowest (1.2-4.5%) damage genus are recommended use immunity. stable source material practical will help curb growth pathogen without chemical protection agents.
