BackgroundWild crop relatives have been potentially subjected to stresses on an evolutionary time scale prior to domestication. Among these stresses, drought is one of the main factors limiting crop productivity and its impact is likely to increase under current scenarios of global climate change. We sought to determine to what extent wild common bean (Phaseolus vulgaris) exhibited adaptation to drought stress, whether this potential adaptation is dependent on the climatic conditions of the location of origin of individual populations, and to what extent domesticated common bean reflects potential drought adaptation.MethodsAn extensive and diverse set of wild beans from across Mesoamerica, along with a set of reference Mesoamerican domesticated cultivars, were evaluated for root and shoot traits related to drought adaptation. A water deficit experiment was conducted by growing each genotype in a long transparent tube in greenhouse conditions so that root growth, in addition to shoot growth, could be monitored.ResultsPhenotypic and landscape genomic analyses, based on single-nucleotide polymorphisms, suggested that beans originating from central and north-west Mexico and Oaxaca, in the driest parts of their distribution, produced more biomass and were deeper-rooted. Nevertheless, deeper rooting was correlated with less root biomass production relative to total biomass. Compared with wild types, domesticated types showed a stronger reduction and delay in growth and development in response to drought stress. Specific genomic regions were associated with root depth, biomass productivity and drought response, some of which showed signals of selection and were previously related to productivity and drought tolerance.ConclusionsThe drought tolerance of wild beans consists in its stronger ability, compared with domesticated types, to continue growth in spite of water-limited conditions. This study is the first to relate bean response to drought to environment of origin for a diverse selection of wild beans. It provides information that needs to be corroborated in crosses between wild and domesticated beans to make it applicable to breeding programmes.

“…Esto último diferencia estadísticamente el grupo de genotipos biofortificados respecto al testigo regional, pues evidencia tiempos menores de cocción en relación con los 90,5 minutos que presentó el genotipo regional. En este sentido, en otros estudios de evaluación de fríjoles con contenidos similares de proteína (20 %), dichos contenidos no se relacionaron con el tiempo de cocción, con valores entre los 95 y los 110 minutos (Acosta-Gallegos et al 2011).…”

“…Los genotipos seleccionados SMR43 y SMR39 han sido descritos en otros estudios de fríjol como dotados con un alto contenido de hierro y zinc y con resistencia a enfermedades (Acosta-Gallegos et al 2011). La resistencia a enfermedades está asociada a la inducción abiótica por minerales, ya que estos pueden inhibir la acción de las enzimas pectolíticas de los hongos (CIAT 1986).…”

La ingesta de proteína y micronutrientes en el Caribe seco colombiano en los últimos años ha sido motivo de preocupación pues cerca del 57 % de sus habitantes tiene déficit de aminoácidos, hierro (Fe) y zinc (Zn) en su dieta. Este artículo muestra los resultados de la evaluación multilocal agronómica de rendimiento y calidad de la semilla de nueve genotipos de fríjol biofortificado y un testigo local en el Cesar. La metodología incluyó la caracterización química y microbiológica del suelo, la evaluación de reacción a plagas y enfermedades, la valoración multilocal por AMMI y la selección de dos genotipos con el mejor comportamiento y contenido nutricional por ACP. Adicionalmente, para los genotipos priorizados, se determinó el coeficiente de correlación de Pearson en el contenido de micronutrientes de semilla por localidades y años. Los genotipos biofortificados superaron significativamente en rendimiento y precocidad al testigo. Según el ACP, el grupo de biofortificados se diferenció del testigo en contenido de hierro y zinc en la semilla, lo cual confirmó su superioridad en calidad nutricional, y una mayor resistencia a plagas y enfermedades. El AMMI arrojó que el genotipo SMR43 evidenció estabilidad y predictibilidad entre ambientes y el SMR39 tuvo adaptación específica en la mejor localidad para producción de grano. Ambos genotipos conservaron niveles elevados de micronutrientes entre localidades y a lo largo del tiempo según correlación de Pearson.

Yield Performance and Response to High Plant Densities of Dry Bean (Phaseolus vulgaris L.) Cultivars under Semi-Arid Conditions

To identify eco-efficient bean cultivars that can be planted at high densities for sustainable bean production under climate change, this study analyzed the performance of ten dry bean (Phaseolus vulgaris L.) cultivars grown at 90,000, 145,000 and 260,000 plants ha−1 under rainfed semi-arid conditions in Mexico. The study compared the yield and yield components (leaf area index (LAI), pods per plant, and hundred seed weight) of the cultivars. We also analyzed the dry matter distribution (DMD), growth rate (GR), radiation use efficiency (RUE), and harvest index (HI) of the best performing cultivars to determine how they respond to higher densities. The cultivars were established under similar planting and management conditions during two growing seasons. The precipitation for the first and second seasons were 175 and 492 mm, respectively, representing 57% and 160% of the mean precipitation in the area during the July–October growing period. Pinto Saltillo, a drought-tolerant indeterminate semi-prostrate cultivar, and Azufrado 2, a determinate shrub cultivar, performed best at high densities under low-precipitation conditions (175 mm). Both cultivars responded to the highest density (260,000 plants ha−1) with increases of 54% to 69% (0.7 to 1.1) in LAI and 21% to 86% (0.32–0.81 Mg ha−1) in yield. The two cultivars responded to increasing plant density with a modification in their fraction of DMD over plant parts and a change in their GR from 0.23–0.25 at low density to 0.96–1.74 gr m−2 day−1 at high density. The two cultivars had an RUE of 3.8 to 4.4 g MJ−1 and HI of 0.31 to 0.36 at high planting density. Farmers’ use of these commercially available cultivars proven to have high yields and the ability to respond favorably to high densities under rainfed conditions can be a viable short-term strategy to increase dry bean production for sustainable agriculture in semi-arid temperate regions.
