Genetic Progress in Grain Yield and Physiological Traits in Chinese Wheat Cultivars of Southern Yellow and Huai Valley since 1950 (2017, background): “An optimum PH can fully extract maximum yield potential (Fischer, 2007).”
Maximum Attainable Wheat Yield and Resource‐Use Efficiency in the Southern Great Plains (2015, background): “Thus, increasing kernels per square meter increases wheat sink strength, leading to greater yields (Fischer, 2007).”
Wheat physiology: a review of recent developments (2011, methodology): “Much of these developments are captured in the reviews byEvans et al. (1975), Slafer et al. (1999), Passioura (2002), Fischer (2007) and Reynolds et al. (2009).”
Optimizing dry-matter partitioning for increased spike growth, grain number and harvest index in spring wheat (2019, background): “…in spring wheat549 Values of HI in the present study, and those reported elsewhere for winter (ca. 0.50-0.55) and550 spring wheat (ca. 0.45-0.50) (Fischer 2007, 2011; Foulkes et al., 2011), are much less than the551 theoretical limit for HI of ca. 0.62 (Austin 1980), indicating scope to raise HI…”
Yield improvement and adaptation of wheat to water-limited environments in Australia—a case study (2014, background): “Experiments with historic sets of varieties have shown that the dwarfing genes have been important globally to improve HI and thereby grain yield of wheat (e.g. Fischer 2007).”
