“…Several of the better performing bean lines also showed a high expression of traits associated with the mobilization of photosynthates, by showing greater relationship between PPI and GY in lines such as G 40027, SEN 46, SMN 99, G 40001, BFS 10 and SMC 140. These lines showed better ability to partition larger amounts of biomass from vegetative organs such as leaves and stems toward pod formation resulting in higher PPI and also HI values (Omae et al 2006;Rao et al 2017;Suárez et al 2018). It is possible that the superior agronomic performance of these lines could be attributed to greater transport of photosynthates from source organs and download of sugars to sink organs (Soltani et al 2019).…”

Adaptation of common bean lines to high temperature conditions: genotypic differences in phenological and agronomic performanceThe International Center for Tropical Agriculture (CIAT) believes that open access contributes to its mission of reducing hunger and poverty, and improving human nutrition in the tropics through research aimed at increasing the eco-efficiency of agriculture.CIAT is committed to creating and sharing knowledge and information openly and globally. We do this through collaborative research as well as through the open sharing of our data, tools, and publications.

“…Two field studies were conducted at the main experimental station of CIAT near Palmira, Colombia (3°29¢ N, 76°21¢ W) at an altitude of 965 m asl during the dry seasons ( June-September) high shoot vigor under drought (SXB05; Assefa et al, 2013), drought and low-fertility adaptation (BFS10; Beebe et al, 2008;Suarez-Salazar et al, 2019), and genotypes described as drought resistant by CIAT due to their high yields under drought conditions (DAB 295, DAB 494;Polania et al, 2016b;Suarez-Salazar et al, 2019). Drought-sensitive lines were selected for their commercial use and known sensitivity to drought (Assefa et al, 2013;Polania et al, 2016aPolania et al, , 2017aDiaz et al, 2018).…”

Accurate assessment of crop water uptake (WU) and water use efficiency (WUE) is not easy under field conditions. Carbon isotope discrimination (Δ13C) has been used as a surrogate of WUE to examine crop yield responses to drought and its relationship with WU and WUE. A 2‐yr study was conducted (i) to characterize genotypic variation in Δ13C, grain yield, and other physiological parameters in common bean (Phaseolus vulgaris L.) parental lines, and (ii) to examine the relationships between grain Δ13C, shoot Δ13C, and grain yield under well‐watered and terminal drought stress conditions. All measured plant traits were strongly influenced by water availability, and genotypic differences in grain yield, shoot Δ13C, and grain Δ13C were found in both watered and terminal drought stress environments. The parental lines were classified into two drought adaptation groups, drought resistant and drought sensitive, based on a yield drought index. High yields under drought conditions were related to (i) greater water uptake, as indicated by high Δ13C in genotypes previously shown to have deeper roots (e.g., SEA 5 and BAT 477), and (ii) increased WUE, denoted by lower Δ13C and greater pod harvest index (PHI) (e.g., SER 16). Coupling of Δ13C measurements with measured yield and yield components analyses, such as PHI, provided an avenue to distinguish different physiological traits among drought resistant genotypes underlying adaptation to water deficit stress.

“…On-farm maize trials in Africa have shown that drought-tolerant maize can yield between 20-25% more than current commercial varieties, with no yield penalty in 'good' years (Cairns & Prasanna, 2018;Setimela et al, 2017). Suárez Salazar et al (2018) identified common bean lines adapted to a heat-stress environment in the Colombian…”

Crop improvement efforts aiming at increasing crop production (quantity, quality) and adapting to climate change have been subject of active research over the past years. But, the question remains 'to what extent can breeding gains be achieved under a changing climate, at a pace sufficient to usefully contribute to climate adaptation, mitigation and food security?'. Here, we address this question by critically reviewing how model-based approaches can be used to assist breeding activities, with
