Drought Tolerance in Maize: Indirect Selection through Secondary Traits versus Genomewide Selection (2013, result): “…to improve abiotic stress tolerance have led to conflicting results: some studies found that indirect selection was inefficient (Atlin, 2003; Lafitte et al., 2003; Venuprasad et al., 2007) whereas other studies found that indirect selection was efficient (Sinebo et al., 2002; Gallais et al., 2008).”
Global synthesis of drought effects on cereal, legume, tuber and root crops production: A review (2017, background): “Rice was very sensitive to drought during the reproductive phase to the extent that even direct selection for drought-tolerant plants using yield per se (rather than secondary traits) during reproductive-stage drought was effective (Venuprasad et al., 2007).”
Identification of Drought, Heat, and Combined Drought and Heat Tolerant Donors in Maize (2013, background): “Soil moisture monitoring has routinely been used in rice for drought breeding, to reduce variation in drought stress between experiments and years (Lafitte et al. 2006; Venuprasad et al. 2007 and 2008) and needs to be applied within maize breeding for drought tolerance in ESA.”
Genetic engineering and breeding of drought-resistant crops. (2014, background): “Drought stress at the reproductive stage can directly result in an average yield loss of more than 50% (14, 114).”
Genetic Gains in Grain Yield Through Genomic Selection in Eight Bi-parental Maize Populations under Drought Stress (2015, background): “Also, direct selection for grain yield under drought is often more difficult due to the low heritability of grain yield under stress (Edmeades et al., 1999; Venuprasad et al., 2007; Ziyomo and Bernardo 2013).”
Rice Breeding for High Grain Yield under Drought: A Strategic Solution to a Complex Problem (2014, background): “The unpredictable nature of rainfall across different seasons makes it difficult to achieve similar intensities of drought in all environments to identify and select the best suited breeding material [14].”
Characterization of the effect of a QTL for drought resistance in rice, qtl12.1, over a range of environments in the Philippines and eastern India (2009, background): “…Atlin International Wheat and Maize Improvement Center (CIMMYT), Apdo Postal 6-641, 06600 Mexico City, Mexico are difficult to impose even when managed-stress screening is performed during the dry season (Courtois et al. 2000; Lafitte et al. 2006; Venuprasad et al. 2007; Bernier et al. 2008).”
The large-effect drought-resistance QTL qtl12.1 increases water uptake in upland rice (2009, positive): “Recently, direct selection for grain yield under managed drought stress has been found to be effective in improving drought resistance (Venuprasad et al., 2007; Kumar et al., 2008; Venuprasad et al., 2008), but the reliable application of managed stress is not possible for most upland rice breeding ”
Plant drought stress: effects, mechanisms and management (2011, positive): “Selection response in the target population of environments under natural stress can be considered a correlated response to selection in the managed stress environment (Venuprasad et al., 2007).”
Drought Resistance Improvement in Rice: An Integrated Genetic and Resource Management Strategy (2011, background): “・Proof of concept that conventional breeding based on direct selection for yield under artificially imposed drought stress can result in actual gains in drought resistance (Venuprasad et al., 2007; Kumar et al., 2008; Lafi tte et al. 2006; Jongdee et al., 2006).”
Efficiency of Managed‐Stress Screening of Elite Maize Hybrids under Drought and Low Nitrogen for Yield under Rainfed Conditions in Southern Africa (2012, background): “While Venuprasad et al. (2007) indicated that rice (Oryza sativa L.) genotypes selected in managed drought trials were also adapted to randomly occurring drought, information on the relative effi ciency of indirect selection under optimal, managed drought, and low-N conditions for genotypes adapted…”
