Synthetic Hexaploids: Harnessing Species of the Primary Gene Pool for Wheat Improvement (2013, background): “Arguably, increases in grain yields of common wheat over the last several decades came in part from the use of gibberellic acidsensitive dwarfing genes (Rht1 and Rht2), which were widely distributed during the “green revolution” (Smale et al. 2002).”
The Contribution of Breeding to Yield Advances in maize (Zea mays L.) (2005, background): “…beneficial genetic response (timely and wide-ranging) to new and/or unusual kinds of biotic or abiotic stress (FAO, 1996; Gollin and Smale, 1998; National Research Council (U.S.) Committee on Genetic Vulnerability of Major Crops, 1972; Rosenow and Clark, 1987; Simmonds, 1962; Smale et al., 2002).”
Genetic Gains for Grain Yield in CIMMYT Spring Bread Wheat across International Environments (2012, background): “In addition, outstanding CIMMYT-derived bread wheat lines have been widely used in crossing programs across the developing world (Braun et al., 1996) and have greatly enriched the genetic diversity of wheat cultivars in many countries (Smale et al., 2002).”
High yield potential, shuttle breeding, genetic diversity, and a new international wheat improvement strategy (2007, background): “Furthermore, cross-breeding of local germplasm with CIMMYT materials suggests that genetic diversity is at least as great as that shown by CIMMYT bred-germplasm, indicating that genealogical and genetic diversity was ‘‘accomplished through the open exchange of large numbers of diverse materials amon”
Molecular markers: actual and potential contributions to wheat genome characterization and breeding (2007, background): “The analysis of diversity changes over time among accessions in wheat collections revealed no declining trends (Donini et al. 2000; Christiansen et al. 2002; Smale et al. 2002; Stehno et al. 2003; Khlestkina et al. 2004a, b; Landjeva et al. 2006a).”
Farmer management of production risk on degraded lands: the role of wheat variety diversity in the Tigray region, Ethiopia (2007, background): “CIMMYT ancestry entails complex genealogies with parental lines from international sources (Smale et al., 2002).”
Crop genetic diversity, farm productivity and the management of environmental risk in rainfed agriculture (2006, background): “This process results in lengthening variety pedigrees to confer tolerance, resistance and yield potential (Evenson and Gollin, 1997; Smale et al. 2002).”
Impacts of breeding on international collaborative wheat improvement (2006, background): “The results for all of the measures of diversity show significant increases over this period (Smale et al. 2002).”
Bringing wild relatives back into the family: recovering genetic diversity in CIMMYT improved wheat germplasm (2006, background): “CIMMYT-derived wheats are grown widely in the developing world ( Smale et al., 2002 ) and have also contributed significantly to the wheat industries of developed countries such as Australia (Brennan & Fox, 1998) and the USA (van Beuningen & Busch, 1997).”
Genetic erosion in crops: concept, research results and challenges (2009, background): “Pedigree studies do demonstrate that breeders are able to harness variation from a wide range of sources (Smale et al., 2002), which suggests that the modernization bottleneck cannot be simply characterized as a population bottleneck, resulting from the use of a limited number of original ancestors ”
