Breeding for improved water productivity in temperate cereals: phenotyping, quantitative trait loci, markers and the selection environment (2010, background): “5–15mm) but it translates to an almost doubling of water use efficiency for grain production to ~35 kg/ha mm compared with the season long water use efficiency (Manschadi et al. 2006; Kirkegaard et al. 2007).”
Traits and selection strategies to improve root systems and water uptake in water-limited wheat crops. (2012, methodology): “62 t ha (1), equating to 59 kg ha 1 for every additional millimetre (Kirkegaard et al., 2007).”
The large-effect drought-resistance QTL qtl12.1 increases water uptake in upland rice (2009, positive): “It has been estimated, based onmodel simulations inwheat, that every extramillimeter ofwater transpired leads to a yield gain of 20–60 kg ha 1 in well-managed disease-free cereal crops (Manschadi et al., 2006; Passioura, 2006; Kirkegaard et al., 2007).”
Small temporal differences in water uptake among varieties of pearl millet (Pennisetum glaucum (L.) R. Br.) are critical for grain yield under terminal drought (2013, positive): “These values are close to those previously reported for wheat: each millimetre of water extracted during grain filling led to a yield increase of 55 kg ha−1 (Manschadi et al. 2006) or 59 kg ha−1 (Kirkegaard et al. 2007).”
Effective use of water (EUW) and not water-use efficiency (WUE) is the target of crop yield improvement under drought stress (2009, background): “An effective means of achieving reproductive success under drought stress is soil moisture capture by deep root system where deep soil moisture is available (e.g. Kirkegaard et al., 2007).”
Wheat physiology: a review of recent developments (2011, background): “Such water could have been used during grain filling very efficiently since it is not subject to evaporative losses and all assimilation then goes to the grain: thus Kirkegaard et al. (2007) measured grain efficiencies of up to 60 kg/ha.mm when crops were subirrigated at depth during grain filling.”
Yield, transpiration efficiency, and water-use variations and their interrelationships in the sorghum reference collection (2011, background): “2006) and 59 kg ha grain yield (Kirkegaard et al. 2007), respectively.”
Genotypic variation in seedling root architectural traits and implications for drought adaptation in wheat (Triticum aestivum L.) (2008, background): “It has been shown in wheat (Manschadi et al. 2006; Kirkegaard et al. 2007) and sorghum (Hammer 2006) that small amounts of water “shifted” from pre- to post- anthesis in this way can have major effects on grain yield in water-limited situations.”
