“…Other noteworthy accessions in this regard were found, such as P. maculatus from Cuatro Ciénegas, Coahuila, where precipitation is 18.5 mm per month, and P. purpusii from Charcas, San Luis Potosí, with 30.3 mm of precipitation per month. Both species may be useful for analyzing and understanding the mechanisms of resistance to low water stress (Delgado-Salinas & Gama-López, 2015;Delgado-Salinas et al, 2006;Hernández-Delgado et al, 2015;Redden et al, 2015;Singh et al, 2014). In this regard, drought resistance genes have been reported in P. maculatus (Lioi et al, 2007).…”

Despite its economic, social, biological, and cultural importance, wild forms of the genus Phaseolus are not well represented in germplasm banks, and they are at great risk due to changes in land use as well as climate change. To improve our understanding of the potential geographical distribution of wild beans (Phaseolus spp.) from Mexico and support in situ and ex situ conservation programs, we determined the climatic adaptation ranges of 29 species and two subspecies of Phaseolus collected throughout Mexico. Based on five biotic and 117 abiotic variables obtained from different databases—WorldClim, Global‐Aridity, and Global‐PET—we performed principal component and cluster analyses. Germplasm was distributed among 12 climatic types from a possible 28. The general climatic ranges were as follows: 8–3,083 m above sea level; 12.07–26.96°C annual mean temperature; 10.33–202.68 mm annual precipitation; 9.33–16.56 W/m2 of net radiation; 11.68–14.23 hr photoperiod; 0.06–1.57 aridity index; and 10–1,728 mm/month of annual potential evapotranspiration. Most descriptive variables (25) clustered species into two groups: One included germplasm from semihot climates, and the other included germplasm from temperate climates. Species clustering showed 45% to 54% coincidence with species previously grouped using molecular data. The species P. filiformis, P. purpusii, and P. maculatus were found at low‐humidity locations; these species could be used to improve our understanding of the extreme aridity adaptation mechanisms used by wild beans to avoid or tolerate climate change as well as to introgress favorable alleles into new cultivars adapted to hot, dry environments.

“…However, when there are surpluses, they are sold through either local or regional markets [15,16,71]. In several cases, landraces are only regionally or sporadically known nationwide [28] even when remarkable potential has been fully identified in local genetic pools through agronomic, molecular and biochemical assessments [36,72,73].…”

Grain legumes are considered major sources of dietary proteins, calories, certain minerals and vitamins, and they are the most widely cultivated and consumed crops worldwide. Among them are the common beans, whose major production volumes came from landraces cultivated in traditional farming systems. The objective of this study was to evaluate the phenotypic diversity of a set of common bean landraces from Mexico based on the agromorphological traits and nutritional composition of the grain in the context of traditional farming systems. Different field and laboratory data were collected and complemented with secondary information published in refereed journals and research reports. The results showed that there are significant differences in the morphological and physiological traits of the plant, pod and grain among groups of common bean landraces of different geographic origins, which were associated with different indigenous groups. Similar patterns were observed in the contents of anthocyanins, polyphenols, flavoinds and minerals as well as antioxidant activity. In the evaluated population groups in each region, there are outstanding populations in terms of agromorphological traits and the nutritional value of the grain that can enable a participatory breeding initiative guided by regional objectives. Some populations from Sierra Norte, Oaxaca, presented higher values in Zn and Fe, and populations from Estado de Mexico exhibited high polyphenol and flavonoid values but stable agronomic behaviour.

“…However, P. vulgaris also has some problems due to the presence of certain anti-nutritional compounds such as saponins, flatulence factors, lectins, and phytic acid, and it also needs prolonged cooking [21,22]. P. vulgaris fixes nitrogen to the soil through rhizobia by nitrogenfixing bacteria [23].…”

Rediscovery of Landraces as a Resource for the Future

Phaseolus vulgaris L. of the family Fabaceae is widely grown for essential nutrients in its edible leaves, immature pods, and mature seeds. Landraces are local crops with wide morphological and genetic diversity. Morpho-agronomically, P. v u l g a r i s landraces vary exceptionally in their vegetative and reproductive traits. These landraces vary in their germination rate and final percentage. Their growth form varies from bushy to vining type. Flowers range in their time to flowering, color, and size. Pods also vary widely in their time to pod formation; pod size, color, and shape; number of pods per plant; and time to pod maturity. Seeds also vary in their size, shape, color, and mass, as well as their number per pod and per plant. These landraces also vary in their resistance to pests and diseases from seed germination, plant growth and yield, and seed storage duration. A review on variation among P. v u l g a r i s landraces forms basis for their future breeding as they are a good source of genetic diversity. This enables a possible selection for leaf, pod, and seed consumption, as well as resistance toward pests and diseases during the entire growth.
