Common bean (Phaseolus vulgaris) is cultivated throughout Latin America and Africa, and for the European community, in Italy and Spain, areas are mainly subjected to drought stress which is predict to worsen by regional climatic models. The aims of this work were to identify the drought‐tolerant and drought‐sensitive bean landraces using drought tolerance and phenotypic plasticity indexes and to dissect the root morphological and 2D‐architecture traits related to drought tolerance. Thirty‐one landraces from diverse gene pools and areas of the Calabria region (South Italy), with different habits and morphological traits, were screened for drought tolerance in a hydroponic system. Root phenotyping was conducted by image analysis. Drought tolerance screening identified two landraces as drought tolerant and sensitive, respectively. Under drought stress, the drought‐tolerant landrace exhibited several interesting root traits such as a higher root length, surface area and, above all, the fineness of the whole root systems and, with emphasis, of the higher order roots. Drought stress induced plastic root responses in both bean landraces but with contrasting patterns. The drought‐tolerant landrace exhibited a dimorphic‐rooted strategy, which could be included in future utility for bean breeding programmes in drought‐prone environments.

“…Significant progress may require several cycles of selection and the use of multiple parents as sources of favorable alleles. Despite multi-genic inheritance, genotype 9 environment interactions, and environmental variability associated with tolerance to abiotic stress, bean breeders have developed cultivars and breeding lines with enhanced tolerance to many important abiotic stresses such as drought (Brick et al 2008;Muñoz-Perea et al 2006;Frahm et al 2004), low soil P (Beebe et al 2008;Lynch 2007), and high temperature (Beaver et al 2008;Rosas et al 2000a).…”

Common bean (Phaseolus vulgaris L.) improvement programs have been successful using conventional breeding methods to accomplish a wide array of important objectives. Specific achievements include the extension of range of adaptation of the crop, the development of cultivars with enhanced levels of disease and pest resistance and breeding lines that possess greater tolerance to drought. The most effective breeding method depends on the expression and inheritance of the trait to be selected and the target environment. Many bean improvement programs use molecular markers to facilitate cultivar development. In fact, several recent germplasm releases have used molecular markers to introgress and or pyramid major genes and QTL for disease resistance. Related species (P. coccineus and P. acultifolius) via interspecific hybridizations remain an important albeit long-term source for resistance to economically important diseases. Slow progress has been made in the improvement of traits such as adaptation to low soil fertility and tolerance to high levels of soluble Al in the soil using conventional breeding methods. The inability to directly measure root traits and the importance of genotype 9 environment interaction complicate the selection of these traits. In addition, symbiotic relationships with Rhizobium and mycorrhiza need to be taken into consideration when selecting for enhanced biological N fixation and greater or more efficient acquisition of soil P. Genomic examination of complex traits such as these should help bean breeders devise more effective selection strategies. As integration of genomics in plant breeding advances, the challenge will be to develop molecular tools that also benefit breeding programs in developing countries. Transgenic breeding methods for bean improvement are not well defined, nor efficient, as beans are recalcitrant to regeneration from cell cultures. Moreover, if issues related to consumer acceptance of GMOs cannot be resolved, traits such as herbicide tolerance in transgenic bean cultivars which would help farmers reduce production costs and decrease soil erosion will remain unrealized.

“…Similar to days to maturity, the most stressful conditions in Table 3. For example, more recently released CO46348 (Brick et al, 2008), Buster, and UI 320 (Myers et al, 2001) had the largest mean seed weight in the seven PS. As a market class, pinto had the largest mean seed weight (33 g 100 seeds −1 ) and red the smallest (29 g 100 seeds −1 ).…”

High‐yielding cultivars adapted to stressed and nonstressed production systems (PS) would maximize efficiency of soil water and nutrient usage, compete well with weeds, resist diseases and insect pests, and reduce dependence on water, fertilizer, and pesticide. The objectives of this study were to (i) determine the performance of dry bean (Phaseolus vulgaris L.) landraces and cultivars across seven stressed and nonstressed PS, (ii) identify high‐yielding cultivars within and across PS, and (iii) determine associations among PS. Three landraces and 13 cultivars were evaluated for days to maturity, 100‐seed weight, and yield in 2003 and 2004. The PS and genotype effects and their interactions with years were significant (P < 0.01). The mean yield (740 kg ha−1), 100‐seed weight (28 g), and days to maturity (81 d) were least in the on‐farm organic low input (OFOL) PS. The greatest mean yield (2740 kg ha−1) was obtained in the on‐station conventional (OSCN) PS, while the greatest 100‐seed weight (35 g) and days to maturity (95) were obtained in the on‐farm low soil fertility (OFLF) PS. Red genotypes yielded more across all PS. ‘Bill Z’ in OSCN and on‐farm organic high‐input (OFOH) PS, ‘UI 239’ in on‐station continual bean production (OSCB), CO46348 in on‐station drought‐stressed production (OSDS), ‘Matterhorn’ in on‐farm conventional (OFCN), ‘NW 63’ in OFLF, and ‘Buster’ in OFOL had high yield. CO46348, UI 239, NW 63, and Bill Z had high yields across PS. Positive associations for yield in the OFCN occurred with yield across all PS except OFOL. The latter was not correlated with other PS. Thus, testing in the OFCN PS would be pivotal for development of high‐yielding cultivars for diverse PS, while testing at OFOL would need to be done for cultivars developed for use in that PS.
