Evaluation of common bean genotypes for drought tolerance

Abstract: The aim of this study was to evaluate twelve genotypes of common bean for intermittent drought stress and for root growth angle. The water deficit experiments were conducted in 2015 and 2016 in a randomized block experimental design with split plots and three replications. Two treatments were applied: an irrigated treatment and a water deficit treatment, in which irrigation was suspended in pre-flowering and remained suspended up to the time at which the matrix potential of the soil was measured to be near-199… Show more

“…Evaluation of delayed senescence may be helpful for indirect selection of grain and biomass yields in breeding programmes targeting better drought tolerance [225]. Additionally, key physiological characteristics involving water use efficiency [226], root growth [227], carbon isotope discrimination (Δ 13 C) and leaf temperature [149] may be beneficial in screening legume genotypes for drought tolerance. Substantial genetic diversity in chickpea genotypes for carbon isotope discrimination [228] can be used for improvements of root architecture as an indirect indicator in chickpea.…”

“…Quantitative trait loci (QTL) mapping for SG has been performed for the major five cereal crops, wheat [32,33], maize [34,35], rice [36,37], sorghum [38,39], and barley [22]. In maize, the utilization of SG trait in breeding programs results in significant genetic progress for high grain yield and tolerance to abiotic stress (Figure 4).…”

“…However, approximately 60% of the global output is produced in water-stressed environments. The primary reasons for the incomplete exploitation of the yield potential of cultivars developed in plant breeding programs include water deficiency aggravated by disease attacks (Atkinson;Urwin, 2012;Ribeiro et al, 2019). Therefore, the breeding of genotypes capable of thriving under heterogeneous soil-climatic conditions could improve the tolerance of these cultivars to water stress.…”
