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.

“…Wsm2 was eff ective against WSMV at 18°C but ineffective at 24°C (Seifers et al, 2006). Signifi cant environmental eff ects that resulted in inconsistency and unpredictability of the consequences of WSMV infection have been observed in fi eld experiments (Baley et al, 2001;Thomas et al, 2004). Therefore, when comparing resistance to WSMV in wheat cultivars based on observation of disease incidence and severity or studying inheritance of resistance in a population, it is important to minimize environmental eff ects, especially temperature variation, that could potentially confound the experiment.…”

Wheat streak mosaic (WSM), caused by Wheat streak mosaic virus (WSMV), is a devastating disease in wheat (Triticum aestivum L.) in the Great Plains of North America. Use of resistance is an effective and environmentally sound method to control the disease. In this study, six wheat genotypes were compared for their responses to WSMV infection under growth chamber conditions. The three resistant genotypes, KS96HW10‐3 (Wsm1), Mace (Wsm1), and CO960293‐2, had disease scores significantly lower than the remaining three genotypes without major resistance. Disease in TAM 111 and TAM 112 was consistently less severe than Karl 92. A population consisting of 188 F2:3 families derived from the cross CO960293‐2 × TAM 111 was used for determining inheritance of the WSMV resistance and for molecular mapping of the resistance in CO960293‐2. Data on segregation of resistance indicated that the resistance in CO960293‐2 is conditioned by a single dominant gene, which was named Wsm2 Transgressive segregation toward susceptibility occurred in the population suggesting a minor gene in the moderately susceptible parent TAM 111, which was not allelic to Wsm2. Wsm2 was mapped to the short arm of chromosome 3B with two flanking simple sequence repeat markers. The single dominant gene inheritance for WSMV resistance in CO960293‐2 has been consistent with the observations that the resistance can be readily transferred to adapted cultivars.

To date, only one gene conferring resistance to Wheat streak mosaic virus (WSMV) designated as Wsm1 was transferred from Thinopyrum intermedium (Host) Barkworth and Dewey to wheat (Triticum aestivum L.) in the form of a compensating Robertsonian translocation T4DL·4JsS. Wsm1 confers high levels of resistance to WSMV under field conditions; however, in certain genetic backgrounds and environments, the presence of the T4DL·4JsS translocation reduces agronomic performance. The objective of this study was to shorten the Th. intermedium segment in the T4DL·4JsS translocation. We recovered one proximal (rec36) and four distal (rec45, rec64, rec87, rec213) primary recombinants. Genomic in situ hybridization and molecular marker analyses determined the size of the Th. intermedium segments in the distal recombinants to be about 20% of the 4DS‐4JsS arm. All primary recombinant stocks, together with appropriate controls, were evaluated for their resistance to WSMV and Triticum mosaic virus (TriMV) in greenhouse tests. Whereas the distal recombinants rec45, rec64, rec87, and rec213 were resistant to both WSMV and TriMV at low temperatures of 18°C, the proximal recombinant rec36 reacted susceptible, which mapped the Wsm1 gene to the distal 20% of the 4DS‐4JsS arm. We successfully shortened the Th. intermedium segment while still retaining the Wsm1 gene. The T4DL·4DS‐4JsS recombinant chromosome of the rec213 stock was transferred to adapted Kansas hard red winter wheat cultivars.
