PAPER PRESENTED AT INTERNATIONAL WORKSHOP ON INCREASING WHEAT YIELD POTENTIAL, CIMMYT, OBREGON, MEXICO, 20–24 MARCH 2006 Understanding the physiological basis of yield potential in wheat (2007, background): “Nevertheless, as KNO and yield progressed in Argentine maize varieties, Luque et al. (2006) also showed no change in source/sink ratio during grain filling (crop growth during grain filling/ KNO).”
Coupling time to silking with plant growth rate in maize (2007, background): “Evidence that increased biomass or mean plant growth rate around flowering has contributed to differences between old and new genotypes is inconsistent (Tollenaar, 1991; Tollenaar et al., 1992; Luque et al., 2006 ).”
Genetic improvement in density and nitrogen stress tolerance traits over 38 years of commercial maize hybrid release. (2016, background): “For example, Luque et al. (2006) discussed the lack of breeding focus on KW since it is normally considered to be a more stable parameter in comparison with KN or KNP.”
Kernel number determination differs among maize hybrids in response to nitrogen (2008, background): “Negative effects on biomass allocation to reproductive sinks had been attributed to differences among hybrids in the response to increased stand density (Echarte et al., 2004; Luque et al., 2006), and a PGRcp of 2 g plant 1 d 1 is considered a threshold below which EGRcp becomes highly unstable (Veg”
Changes in Nitrogen Use Traits Associated with Genetic Improvement for Grain Yield of Maize Hybrids Released in Different Decades (2013, background): “Many of these changes are associated with increased dry matter partitioning to the ear during the critical period for kernel set (Echarte et al., 2000; Luque et al., 2006) and sustained leaf photosynthesis during grain fill (Ding et al., 2005; Echarte et al., 2008).”
Maize Nutrient Accumulation and Partitioning in Response to Plant Density and Nitrogen Rate: I. Macronutrients (2013, methodology): “Hybrid variation for the dry mass relationship has been previously reported (Echarte et al., 2004; Luque et al., 2006; D’Andrea et al., 2008), but the hybrids evaluated in this research were not substantially different in either ear or plant components (<10% variation).”
Gains in Maize Genetic Improvement in Eastern and Southern Africa: I. CIMMYT Hybrid Breeding Pipeline (2017, background): “Under high input conditions, gain for maize grain yield has been estimated at 94.7 kg ha−1 yr−1 in China (Ci et al., 2011), 132 kg ha−1 yr−1 in Argentina (Luque et al., 2006), 80 kg ha−1 yr−1 in Canada (Bruulsema et al., 2000), and 65 to 75 kg ha−1 yr−1 in the United States (Duvick, 2005).”
