Genomic Selection for Quantitative Adult Plant Stem Rust Resistance in Wheat (2014, background): “, 2000) capable of infecting the majority of the worlds’ wheat germplasm (Singh et al., 2006), has highlighted the need for breeding efforts focused on durable stem rust resistance.”
The emergence of Ug99 races of the stem rust fungus is a threat to world wheat production. (2011, background): “WHEAT VARIETIES AND GERMPLASM AGAINST UG99 Over 200,000 wheat varieties, germplasm collections, and advanced breeding materials were screened during 2005–2010 for resistance to Ug99 and its derivative races at Njoro, Kenya, and to a lesser extent, at Kulumsa and Debre Zeit, Ethiopia (43, 44).”
Wheat genetic resources enhancement by the International Maize and Wheat Improvement Center (CIMMYT) (2008, background): “…resistance of some of the older US, Australian, and CIMMYT spring wheat lines and cultivars is believed to be due to the deployment of Sr2 in conjunction with other unknown minor, additive genes that could have originated from ‘Thatcher’ and the ‘Thatcher’-derived line ‘Chris’ (Singh et al. 2006).”
Genomic selection for durable stem rust resistance in wheat (2011, methodology): “A single backcross selected bulk method is one approach to breed for APR ( Singh et al. 2006 ).”
Wheat improvement in India: present status, emerging challenges and future prospects (2007, background): “A set of 19 Indian wheat varieties and 3 genetic stocks were screened under natural outbreak of Ug99 at Njoro (Nakuru), Kenya in the summer nursery 2005.”
The importance of plant health to food security (2010, methodology): “Evidence suggests that Ug99 is now established in the Eastern African highlands and spreading, although extensive field survey results detailing exact distribution are currently unavailable ( Singh et al. 2006 ).”
Species diversity and drivers of spread of alien fungi (sensu lato) in Europe with a particular focus on France (2009, background): “org/newsroom), as predicted by a trajectory analysis model of the prevailing winds (Singh et al. 2006).”
Challenges to wheat production in South Asia (2007, background): “Most of the wheat lines available in South Asia are susceptible to this race due to preponderance of Sr31 gene in these lines (Pretorius et al. 2000; Singh et al. 2006).”
Will stem rust destroy the world's wheat crop? (2008, background): “As described by Singh et al. (2006) Ug99 was first identified in Uganda in 1998, although there is some evidence indicating that the race may have been present in Kenya since 1993, and had spread to most of the wheat growing areas of Kenya and Ethiopia by 2003.”
International surveillance of wheat rust pathogens: progress and challenges (2011, background): “The appearance of Yr9 virulence, initially in east Africa and then progressively throughout Asia in the 1990 s, suggests that much of this region comprises a single rust epidemiological unit (Singh et al. 2006).”
Stem rust resistance in Aegilops tauschii germplasm (2011, background): “…of resistance to race TTKSK and variants described to date, most of the resistance genes have been introgressed from wild relatives of wheat (Singh et al., 2006; Jin et al., 2007) and have not been utilized extensively in agriculture because of linkage between these genes and deleterious…”
Biological Nitrification Inhibition—A Novel Strategy to Regulate Nitrification in Agricultural Systems (2012, neutral): “While a range of translocations including some with smaller segments of Lr#n are being produced, small segments are not always needed, as history has shown that one good centromeric translocation can have a large impact on wheat breeding (Lukaszewski, 2000; Singh et al., 2006).”
