“…KS91H174 and KS91H184 both were derived from CI 17884, a WSMV resistance line carrying Wsm-1 on a chromosome arm translocated from T. intermedium to wheat (Wells et al, 1982). Ninety-six heads were selected from each of either F 5 (populations 1-3) or F 3 (populations 4-6) bulk populations.…”

“…A resistance gene (Wsm1) was identified and transferred from intermediate wheat-grass [Thinopyrum intermedium (Host) Barkworth & DR Dewey] to wheat to limit infection by the virus and WCM colonization (Friebe et al, 1996). Transfer of this resistance traces to crosses between wheat and intermediate wheat-grass produced more than three decades ago (Wells et al, 1973(Wells et al, , 1982. Subsequent breeding led to the development of wheat lines with Wsm1 and the potential to prevent major economic losses.…”

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.

“…The source of resistance in all R-lines is most likely either KS91H184 or KS91H174, both being selected from populations that had been randomly mated for several generations and derived from CI 17884, a WSMV-resistance line carrying the Wsm1 gene on a chromosome arm translocated from Th. intermedium (Wells et al, 1982).…”

The present study used genomic in situ hybridisation (GISH; Schwarzacher et al, 1992) complemented by targeted DNA markers and field evaluation to characterize resistance in Nebraska-adapted winter wheat lines originating from four genetically diverse populations that include the Kansas WSMW-resistant Th.…”

Introgression of chromosome segments from multiple alien species in wheat breeding lines with wheat streak mosaic virus resistance

Pyramiding of alien-derived Wheat streak mosaic virus (WSMV) resistance and resistance enhancing genes in wheat is a costeffective and environmentally safe strategy for disease control. PCR-based markers and cytogenetic analysis with genomic in situ hybridisation were applied to identify alien chromatin in four genetically diverse populations of wheat (Triticum aestivum) lines incorporating chromosome segments from Thinopyrum intermedium and Secale cereale (rye). Out of 20 experimental lines, 10 carried Th. intermedium chromatin as T4DL*4Ai#2S translocations, while, unexpectedly, 7 lines were positive for alien chromatin (Th. intermedium or rye) on chromosome 1B. The newly described rye 1RS chromatin, transmitted from early in the pedigree, was associated with enhanced WSMV resistance. Under field conditions, the 1RS chromatin alone showed some resistance, while together with the Th. intermedium 4Ai#2S offered superior resistance to that demonstrated by the known resistant cultivar Mace. Most alien wheat lines carry whole chromosome arms, and it is notable that these lines showed intra-arm recombination within the 1BS arm. The translocation breakpoints between 1BS and alien chromatin fell in three categories: (i) at or near to the centromere, (ii) intercalary between markers UL-Thin5 and Xgwm1130 and (iii) towards the telomere between Xgwm0911 and Xbarc194. Labelled genomic Th. intermedium DNA hybridised to the rye 1RS chromatin under high stringency conditions, indicating the presence of shared tandem repeats among the cereals. The novel small alien fragments may explain the difficulty in developing well-adapted lines carrying Wsm1 despite improved tolerance to the virus. The results will facilitate directed chromosome engineering producing agronomically desirable WSMV-resistant germplasm.
