Industry-Scale Evaluation of Maize Hybrids Selected for Increased Yield in Drought-Stress Conditions of the US Corn Belt (2015, background): “Breeders have long been selecting for tolerance to biotic and abiotic stress (Cooper et al., 2014a; Duvick et al., 2004; Hammer et al., 2009).”
Response of grain yield to plant density and nitrogen rate in spring maize hybrids released from 1970 to 2010 in Northeast China (2016, background): “, which averages about 80,000 plants ha [17].”
Breeding for Yield Potential and Stress Adaptation in Cereals (2008, unknown): “hybrids (Duvick et al., 2004a).”
Traits and selection strategies to improve root systems and water uptake in water-limited wheat crops. (2012, background): “This appears to be the case with maize breeding in the USA, where annual genetic yield gain of 77 kg ha 1 has been achieved at the optimum plant density for the varieties grown (Duvick et al., 2004).”
Genetic Improvement of U.S. Soybean in Maturity Groups II, III, and IV (2014, background): “Duvick et al. (2004) estimated improvements of hybrids grown from 1930 to 2001 to be 77 kg ha–1 yr–1 when grown at their optimum density.”
Maize response to elevated plant density combined with lowered N-fertilizer rate is genotype-dependent (2015, background): “2 developed countries are characterized by high yielding ability per unit area under high plant densities, owing to morphological and phenological adaptations such as early silking, short anthesis-to-silking interval (ASI), few barren stalks, and prolificacy [6].”
Genome-Wide Reduction of Genetic Diversity in Wheat Breeding (2009, unknown): “Genetic distinctiveness of individual cultivars was estimated as the average dissimilarity of a cultivar against the other cultivars following Fu (2006b) and linear regression of the distinctiveness estimates over the years of cultivar release was made to assess the change in cultivar distinctivenes”
Maize grain yield enhancement through high plant density cultivation with different inter-row and intra-row spacings (2016, background): “The first one is 56 the yield potential per plant, which, over the last 70 years, has remained stable for 57 non-stressed plants under very low planting densities (1 plant m-2) (Duvick et al., 2004a; 58 Sangoi et al., 2002).”
The leaf angle distribution of natural plant populations: assessing the canopy with a novel software tool (2015, background): “All these requirements are essential for knowledge-guided crop breeding [24,25], where the rating by visual judgment is still the most common method.”
Model-assisted phenotyping and ideotype design (2015, background): “While crop management is often added in a second step as an effective driver to complement genetic gains, greatest productivity improvement may arise when combining together both breeding and agronomic practices (e.g. Duvick et al., 2004) (Fig.”
