“…In addition, four RWA resistant feed barleys have been released for RWA management. ÔBurtonÕ, with resistance derived from STARS 9301B, was the Þrst RWAresistant feed barley cultivar developed for release in 2004 in the United States (Bregitzer et al 2005). Since then, three other feed barleys, containing either resistance from STARS 9301B or STARS 9577B, were released for commercial use (Bregitzer et al 2008).…”

The Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), is a serious wheat, Triticum aestivum L., and barley, Hordeum vulgare L., pest throughout the small grain-producing areas in the western United States. The virulency and classification of recently described Russian wheat aphid biotypes 1-7 (RWA1-7) were clarified using 24 plant differentials. These seven biotypes had been described previously using various methods and test environments; therefore, the purpose of this study was to test them all under uniform environmental conditions. RWA1 was the least virulent of the biotypes tested, with susceptible ratings observed in five plant differentials and intermediate ratings observed in four plant differentials. RWA4, RWA5, RWA6, and RWA7 had intermediate virulence. RWA4, RWA5, and RWA7 share similar responses, with susceptible responses in six plant differentials and intermediate responses in five plant differentials. Small differences within a few plant differentials separate RWA4, RWA5, and RWA7. RWA6 has susceptible responses with only four plant differentials, but 10 plant differentials had intermediate responses. RWA3 was highly virulent, with susceptible responses in 10 plant differentials and intermediate responses in five plant differentials. RWA2 was the most virulent strain tested with susceptible responses to 12 plant differentials and intermediate responses to five plant differentials. This study has demonstrated that RWA1-7 have different combinations of virulence to the plant differentials tested, thereby confirming previous Russian wheat aphid biotype designations.

“…All RWA-resistant springhabit cultivars released within the United States (Burton, RWA1758, Sidney, and Stoneham) have been derived from either STARS9301B or STARS9577B (Bregitzer et al, 2005Mornhinweg et al, 2009Mornhinweg et al, , 2012b, both of which possess the favorable alleles at the 1H, 2H, 3H, and 7H loci identified by this study. Genotypic variability can now be identified among adapted R germplasm lines that can guide parental selection for developing new cultivars that will likely offer diversity for resistance relative to existing cultivars.…”

“…This study showed that the two main sources of resistance used to develop resistant germplasm (STARS9301B and STARS9577B) may offer limited diversity for RWA resistance. All RWA-resistant springhabit cultivars released within the United States (Burton, RWA1758, Sidney, and Stoneham) have been derived from either STARS9301B or STARS9577B (Bregitzer et al, 2005Mornhinweg et al, 2009Mornhinweg et al, , 2012b, both of which possess the favorable alleles at the 1H, 2H, 3H, and 7H loci identified by this study. A winter-habit cultivar released in the United States, Mesa (PVP 201400309), derives its resistance from R017, which contained the favorable alleles only at 2H and 7H.…”

“…Fortunately, highly effective genetic resistance is available (Bregitzer et al, 2003), and agronomically unadapted R and MR accessions have been identified in the USDA-ARS National Small Grains Collection (http://ars.usda.gov/Main/docs.htm?docid = 21891). Selections from some of these accessions have been used to develop adapted resistant germplasm and cultivars (Bregitzer et al, 2003(Bregitzer et al, , 2005Mornhinweg et al, 1995Mornhinweg et al, , 1999Mornhinweg et al, , 2007aMornhinweg et al, , 2007bMornhinweg et al, , 2008Mornhinweg et al, , 2009Mornhinweg et al, , 2012aMornhinweg et al, , 2012b. Identification and development of these resources depended on phenotypic screens for resistance, which, although relatively simple and highly effective, provided little information on the genetic diversity for resistance.…”

Russian wheat aphid (RWA) [Diuraphis noxia (Mordvilko)] is an increasing problem on barley (Hordeum vulgare L.) throughout the world. Genetic resistance has been identified and used to create barley germplasm and cultivars adapted to the United States. Several mapping studies have been conducted to identify loci associated with resistance, but questions remain, particularly regarding the extent of genetic diversity among resistance sources and improved lines and cultivars. Association analysis of resistant (R) and moderately resistant (MR), unadapted accessions held in the USDA–ARS National Small Grains Germplasm Collection, adapted germplasm lines derived from these accessions, and susceptible (S) elite cultivars was conducted using 4509 single nucleotide polymorphisms (SNPs) to identify markers linked to resistance. Resistance was associated with loci on chromosomes 1H, 2H, 3H, 5H, and 7H at p‐values <0.0001, and the major 1H and 3H loci identified in previous tests were confirmed. However, the genetics of RWA resistance was shown to be complex, and it is likely that loci involved in resistance in some lines were not identified. Nevertheless, this analysis identified diversity among R lines and showed that most of the released RWA‐resistant cultivars had similar genotypes at loci associated with resistance. This analysis also identified R lines that were genetically dissimilar to the released cultivars at these loci. This information can guide parental selection for future breeding efforts designed to capture and deploy greater diversity for RWA resistance among new barley cultivars.

“…It derives its RWA resistance from STARS 9577B (Mornhinweg et al, 1999), which was selected from CIho 4165, a landrace collected in Afghanistan. This source of resistance is distinct from the resistance in ‘Burton’ (Bregitzer et al, 2005). Burton's resistance comes from STARS 9301B (Mornhinweg et al, 1995), which was selected from PI 366450, a landrace also collected in Afghanistan.…”

‘RWA 1758’ (Reg. No. CV‐336; PI 648913) is a spring, Russian wheat aphid (Diuraphis noxia Mordvilko) (RWA)–resistant two‐rowed barley (Hordeum vulgare L.) developed by the USDA‐ARS. RWA 1758 was selected and released on the basis of competitive agronomic performance and resistance to damage caused by RWA feeding. RWA 1758 derives from a BC3F3:4 selection from the cross ‘Baronesse’*4/STARS 9577B. It was tested under the experimental designation 01ST1758. STARS 9577B is a six‐rowed spring RWA‐resistant germplasm line developed and released by the USDA‐ARS. STARS 9577B is resistant to the five RWA biotypes known to be present in the United States. STARS 9577B was developed via selection from CIho 4165, a landrace originally collected in Afghanistan. The main component of the resistance is tolerance, conferred by two dominant genes with recessive epistasis.
