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.

“…The second group, representing larger physiological drought response (i.e., larger percent difference), consisted of 4 dry-highland-adapted accessions (eco-geographic race Durango; [ 39 ]) and 3 MAGIC progeny genotypes. Finally, the third group, also representing low physiological drought response, included 3 tepary beans (Big Fields White, G40159, and TEP 22) and a common bean cultivar (Pinto San Rafael) adapted to arid northern Mexican highlands [ 56 ]. In Campaign 3, which represents the maturation stage (R9: [ 53 ]), 2 main genotypic groupings were identified (Fig.…”

Hyperspectral Remote Sensing for Phenotyping the Physiological Drought Response of Common and Tepary Bean

Proximal remote sensing offers a powerful tool for high-throughput phenotyping of plants for assessing stress response. Bean plants, an important legume for human consumption, are often grown in regions with limited rainfall and irrigation and are therefore bred to further enhance drought tolerance. We assessed physiological (stomatal conductance and predawn and midday leaf water potential) and ground- and tower-based hyperspectral remote sensing (400 to 2,400 nm and 400 to 900 nm, respectively) measurements to evaluate drought response in 12 common bean and 4 tepary bean genotypes across 3 field campaigns (1 predrought and 2 post-drought). Hyperspectral data in partial least squares regression models predicted these physiological traits ( R 2 = 0.20 to 0.55; root mean square percent error 16% to 31%). Furthermore, ground-based partial least squares regression models successfully ranked genotypic drought responses similar to the physiologically based ranks. This study demonstrates applications of high-resolution hyperspectral remote sensing for predicting plant traits and phenotyping drought response across genotypes for vegetation monitoring and breeding population screening.

“…Las características mencionadas, además de la longitud y anchura del grano, son necesarias para la descripción de las nuevas variedades de frijol (UPOV, 2015;SNICS, 2017). El oscurecimiento de la testa del grano está relacionado con su calidad, por lo que se considera en la descripción de las variedades (Acosta et al, 2016;Spitti et al, 2019;Rosales y Flores, 2022).…”

La calidad física del grano de frijol influye en la comercialización, se asocia con la morfología y cuantificarla permite identificar genotipos sobresalientes. Por ello, el objetivo fue evaluar las variedades Azufrado Higuera, Azufrado Noroeste y las líneas avanzadas: Mo 19-20-ERR2-9, Mo 19-20-ERR2-11 y Mo 19-20-ERR2-12. El diseño experimental fue bloques al azar con cuatro repeticiones. El rendimiento (t ha-1), peso de 100 granos (PCG, g) y el brillo del grano (%) se obtuvieron en muestras secas y limpias. El tamaño (mm2), largo, ancho, perímetro (mm), circularidad, color, brillo y luminosidad, de cada grano, se midieron mediante análisis de imágenes digitales. El rendimiento fue desde 2.14 hasta 2.45 t ha-1, sin diferencias entre genotipos. El tamaño de grano mostró correlación (p ≤ 0.05) con el PCG (r = 0.97) y con sus dimensiones (r ≥ 0.94). Las líneas avanzadas presentaron mayor luminosidad del grano (DSH = 0.74, p ≤ 0.05). Las líneas Mo 19-20-ERR2-9 y Mo 19-20-ERR2-11 tuvieron mejor calidad física, evidente en grano de mayor tamaño y con menor oscurecimiento (p ≤ 0.05). El brillo y la luminosidad permiten identificar la oxidación u oscurecimiento de la testa. La oxidación es lenta en Azufrado Noroeste y Azufrado Higuera, mientras que Mo 19-20-ERR2-9, Mo 19-20-ERR2-11 y Mo 19-20-ERR2-12 presentan resistencia.
