Kernel Set in Maize Hybrids and Their Inbred Lines Exposed to Stress (2006, background): “In general, aboveground DM at silking is greater in hybrids than in their parental inbred lines (Sinha and Khanna, 1975; Tollenaar et al., 2004 ), even when plant density of hybrids and inbred lines were manipulated such that they had the same LAI and intercepted radiation (Djisbar and Gardner, 198”
DISSECTION OF PHYSIOLOGICAL PROCESSES UNDERLYING GRAIN YIELD IN MAIZE BY EXAMINING GENETIC IMPROVEMENT AND HETEROSIS (2006, background): “Heterosis for ‘staygreen’ was 91%, which was also a major contributor to differences in dry matter accumulation during the grain-filling period between hybrids and their inbred lines (TOLLENAAR et al., 2004).”
Studies on heritability, correlation and path analysis in maize (Zea mays L.). (2010, background): “Earlier workers (1, 2, 4, 7) identified different traits like ear length, ear diameter, kernels per row, ears per plant, 100-seed weight and rows per ear as potential selection criteria in breeding programmes aiming at higher yield.”
The myth of nitrogen fertilization for soil carbon sequestration. (2007, background): “Harvest index was estimated at 0.5 for corn (Leask and Daynard, 1973; Kiniry et al., 1997; Tollenaar et al., 2004), 0.4 for soybean (Prince et al., 2001), and 0.5 for oats (Prince et al., 2001).”
Breeding for Yield Potential and Stress Adaptation in Cereals (2008, background): “However, the silking dates as well as relative maturity do not differ between modern and old hybrids (Cavalieri and Smith, 1985), which suggest that heterosis has not been responsible for this genetic gain (Tollenaar et al., 2004).”
Maize and soybean root front velocity and maximum depth in Iowa, USA (2018, background): “For example, plant breeding programs have focused on the selection of above ground plant traits for yield improvement (Tollenaar et al., 2004; Tollenaar and Lee, 2006) while giving little attention to the below-ground root morphology (Lynch, 2007).”
