“…Ito et al (2012) reported higher incidence of WSMV in barley (88%) with mite inoculation, while Lehnhoff et al (2015) reported very poor infection (average 13%) when barley was mechanically inoculated with WSMV under field conditions. The average yield losses due to mite inoculation in this study are generally greater but those due to mechanical inoculation are within the 32 to 74% reported in other studies that used mechanical inoculation in susceptible cultivars (Byamukama et al 2014;Fahim et al 2012;Miller et al 2014;Sharp et al 2002). Price et al (2014) reported a decline in WSMV titer across cultivars when plants previously held at high temperatures were moved to low temperatures.…”

“…Cultural practices to reduce WCM populations, and use of resistant or tolerant wheat cultivars, are major strategies employed to manage WSM disease (Graybosch et al 2009;Sharp et al 2002;Wegulo et al 2008). Both virus and vector are dependent on the "green bridge" (hosts growing between the harvesting of one crop and the emergence of the next crop) (Somsen and Sill 1970).…”

Impact of Timing and Method of Virus Inoculation on the Severity of Wheat Streak Mosaic Disease

et al. 2018

Wheat streak mosaic virus (WSMV), transmitted by the wheat curl mite Aceria tosichella, frequently causes significant yield loss in winter wheat throughout the Great Plains of the United States. A field study was conducted in the 2013–14 and 2014–15 growing seasons to compare the impact of timing of WSMV inoculation (early fall, late fall, or early spring) and method of inoculation (mite or mechanical) on susceptibility of winter wheat cultivars Mace (resistant) and Overland (susceptible). Relative chlorophyll content, WSMV incidence, and yield components were determined. The greatest WSMV infection occurred for Overland, with the early fall inoculations resulting in the highest WSMV infection rate (up to 97%) and the greatest yield reductions relative to the control (up to 94%). In contrast, inoculation of Mace resulted in low WSMV incidence (1 to 28.3%). The findings from this study indicate that both method of inoculation and wheat cultivar influenced severity of wheat streak mosaic; however, timing of inoculation also had a dramatic influence on disease. In addition, mite inoculation provided much more consistent infection rates and is considered a more realistic method of inoculation to measure disease impact on wheat cultivars.

“…Previous research on the agronomic and quality effects of Wsm1 has been conducted using spring wheats (Baley et al, 2001;Sharp et al, 2002) in the Northwestern United States.

“…They found Wsm1 provided a benefit in the presence of virus and had no detrimental effects on end use quality or other agronomic traits. Sharp et al (2002) compared classical and transgenic spring wheat cultivars resistant to mechanical inoculation of WSMV. They found that while Wsm1 provides the most effective resistance to WSMV, significant yield penalties were observed in the absence of the virus.…”

Wheat streak mosaic virus (WSMV) is one of the most important diseases limiting winter wheat (Triticum aestivum L.) production in the western Great Plains of North America. There is no known effective WSMV resistance within the primary gene pool of wheat. However, a resistance gene (Wsm1) has been transferred to wheat from a perennial relative, intermediate wheat-grass [Thinopyrum intermedium (Host) . Nebraska-adapted winter wheat lines carrying Wsm1 were used to characterize the effects of this alien introgression on agronomic and quality traits. Sister-lines from six breeding populations were evaluated under virus-free conditions, and under a naturally occurring viral infection. In uninfected locations, no significant difference for grain yield was detected between resistant (R) and susceptible (S) lines, when averaged over populations, but resistant lines had significantly higher test weights. Within populations, significantly higher grain yield was observed only in population 1, while significantly higher test weights occurred in populations 1, 2, 5 and 6. At the infected location, resistant lines were significantly higher in yield in five of six populations. In two of six populations, susceptible lines were significantly higher in bread loaf volume and bake mix time, while in the remaining populations, no significant quality differences were observed. As the Wsm1 gene provided yield advantages under viral infection, and there was no yield detriment in the absence of the virus, its deployment in hard winter wheat cultivars merits consideration.

Eyespot, Cephalosporium stripe, and common root rot are soil-borne diseases that damage the stem bases, vascular system, subcrown internodes,and roots of wheat. Resistance in wheat to these diseases is insufficient to prevent significant yield loss when disease is severe. The wheatgrasses Thinopyrum intermedium and Th. ponticum are highly resistant to these diseases. Identification of disease-resistant wheat-Thinopyrum partial amphiploids, chromosome addition, substitution, and translocation lines makes them a valuable source of resistance genes for wheat breeding programs. Single chromosomes or chromosome segments containing resistance genes can be transferred into wheat to produce genetic stocks that afford a better understanding of the genetic control of resistance in wheatgrasses and new genetic resources for wheat improvement. Resistance to eyespot in Th. intermedium and Th. ponticum was associated with the homoeologous group 4 chromosomes, whereas resistance to Cephalosporium stripe was controlled by genes located on chromosomes 3 and 6 of Th. ponticum. Despite the fact that some eyespot- and common root rot-resistant wheat-Thinopyrum lines have blue kernels, resistance is not tightly linked to the blue aleurone trait. Key words: Thinopyrum intermedium, Th. ponticum, eyespot, Cephalosporium stripe, common root rot, Oculimacula yallundae, O. acuformis, Cephalosporium gramineum, Bipolaris sorokiniana
