“…These genes may still have some value in breeding for stripe rust resistant cultivars, but a large number of genes in the other differentials are no longer very useful as virulences are common in both countries. As rust migrations have occurred between countries and between continents (Stubbs 1985;Nararajan & Singh 1990;Wellings & McIntosh 1990;Brown & Hovmøller 2002;Wellings et al 2003;Hovmøller et al 2008), new virulences or races appearing in one country can spread to another country. Therefore, breeding programs should pay more attention to utilizing non-race specific resistance and should avoid using single genes that are just locally effective.…”

“…in 2002 (Wellings et al 2003). This pathotype differed from eastern Australian Pst pathotypes in its virulence on seedling resistance genes Yr8 and Yr9 and its avirulence on Yr3, Yr4 and Yr34 and some other uncharacterised resistance sources.…”

“…Its popularity declined with the detection of the Pst pathotype 134 E16A? (Wellings et al 2003). This pathotype produced higher stripe rust response on Janz compared to the pre-2002 Pst pathotype 110 E143A?.…”

The Puccinia striiformis f. sp. tritici (Pst) pathotype, 134 E16A?, detected in 2002 in Australia, produced relatively lower and higher adult plant stripe rust responses, respectively, on cultivars Kukri and Janz in comparison to the pre-2002 Pst pathotype 110 E143A?. Molecular mapping of adult plant stripe rust response variation among 180 Kukri/Janz-derived doubled haploid lines over 4 years, two each with Pst pathotypes 110 E143A? and 134 E16A?, was performed. QYr.sun-7B and QYr.sun-7D were consistently contributed by Kukri and Janz, respectively. QYr.sun-7D corresponded to the genomic location of Yr18 and QYr.sun-7B remains to be formally named. QYr.sun-1B, QYr.sun-5B, and QYr.sun-6B were detected during more than one season irrespective of the Pst pathotypes used, whereas QYr.sun-3B was identified only during the 2003 crop season. QYr.sun-1A contributed by Janz, and QYr.sun-2A from Kukri, were detected only against Pst pathotypes 110 E143A? and 134 E16A?, respectively. The DH lines showing better resistance than the either parent carried combinations of 4 to 6 QTL. These lines are currently being used as stripe rust resistance donors in wheat breeding programs.
