“…Conservation of these species is a priority because of their importance in breeding programs (Andueza‐Noh et al., 2016; De Ron et al., 2015; Debouck, 2000; Rodriguez et al., 2015; Shi & Lai, 2015; Singh, Singh, & Dutta, 2014). In addition, further work is needed to reinforce knowledge regarding population genetics and the response to ecological or climate changes and to evaluate survival rates (Delgado‐Salinas & Gama‐López, 2015).…”

“…The best‐studied stress in bean breeding is drought stress (Beebe, Rao, Blair, & Acosta‐Gallegos, 2013; Blair, Cortés, & This, 2016; Miklas et al., 2006; Rodriguez et al., 2015; Villordo‐Pineda, González‐Chavira, Giraldo‐Carbajo, Acosta‐Gallegos, & Caballero‐Pérez, 2015). The most widely used strategy consists of the identification of wild and landrace germplasm resistant to drought stress (Cortés, Monserrate, Ramírez‐Villegas, Madriñán, & Blair, 2013; Porch et al., 2013).…”

“…The use of environmental information in breeding programs has been promoted by the use of methodologies that can predict the presence of specific traits in germplasm growing at specific locations with consequent savings of time and cost (Cortés et al., 2013; Parra‐Quijano et al., 2012; Rodriguez et al., 2015; Song et al., 2015; Thormann et al., 2015; von Wettberg, Marques, & Murren, 2016). However, conservation programs are not considered important by the government and have therefore not received economic support, resulting in the low representation of wild crop relatives in germplasm banks (Castañeda‐Álvarez et al., 2016; Maxted et al., 2016).…”

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.

“…Common beans are now distributed worldwide but were independently domesticated in two different main centers of origin in the Americas (Mamidi et al, 2013); the Mesoamerican gene pool extends from northern Mexico to Colombia, and the Andean gene pool extends from southern Peru to northwestern Argentina ). These gene pools were separated from each other based on isozymes, morphology, and DNA markers (Becerra et al, 2011;Mamidi et al, 2013;Rodriguez et al, 2015). Studies of genetic diversity provide information about segregant populations in recombinant lines, superior genotypes in the progeny, and genetic similarity and dissimilarity information to select future crosses; therefore, they are of critical importance for plant genetic improvement programs (Gepts and Debouck, 1991;Benjak et al, 2005;İpek et al, 2016;Sorkheh and Khaleghi, 2016).…”

The common bean (Phaseolus vulgaris L.) is the most consumed food legume in the world and is a major source of dietary protein, carbohydrates, and valuable micronutrients, especially in developing countries. Diversity Arrays Technology (DArTseq), based on genome reduction with restriction enzymes, provides a rapid, high-throughput, and cost-effective tool capable of generating thousands of genotyped single nucleotide polymorphisms (SNPs) for a genome-wide analysis of genetic diversity. In this study, we aimed to characterize common bean accessions using SNPs detected by a DArTseq approach. A total of 43,018 SNPs were identified from 173 common bean accessions, including Andean and Mesoamerican genotypes. After filtering raw and redundant data, a total of 16,366 SNPs were considered for further analyses. According to population structure analysis, the genotypes were roughly divided into 2 gene pools of Andean and Mesoamerican types. Pairwise fixation index (Fst) values were calculated to resolve the differentiation between populations. This study demonstrated that discovering SNPs from the whole genome is a potential resource for identifying naturally diverse accessions and also the information could be used in breeding programs to develop new common bean varieties.

“…The geographical diversity distribution was studied using unbiased estimates of gene diversity (Nei, 1978) obtained within a moving window of 200-km radius (Rodriguez et al, 2015) over the sampling area. This was achieved using the R package biotools (Silva et al, 2017).…”

ABSTRACT. Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, with a few small area planted in the three main States, where it was previously cultivated (Ceará, Paraíba, and Rio Grande do Norte), but in others, maintenance is accomplished by single dooryard plants. Plants were found in all visited Northeast Brazil municipalities, sometimes in the North of the country, and were collected for ex situ preservation and evaluation. Most of seeds had no fuzz (62.2%) and 94.6% of the genotypes presented spot in flowers. Seventy-one alleles were revealed in 12 loci. The genetic structure of the population evaluated by microsatellite markers shows two main groups, one comprising the Seridó region where landraces were originated and other comprising 2 I.P.P. de Menezes et al. Genetics and Molecular Research 16 (3): gmr16039659 the state of Ceará, where a specific breeding program was developed. Genotypes collected in North Brazil States as well as those collected in Bahia, Alagoas, and Sergipe grouped with those collected in Ceará. The Mantel correlogram indicates a significant (P < 0.05) correlation between genetic and geographical distances up to 77 km. The ex situ maintenance and agronomical evaluation are the main concerns for mocó, as the use of the agricultural interesting traits, possibly introgressed to other genotypes, is predicted. The in situ preservation is still of interest since there is more diversity there than in the collected plants and some should be continued due to use as medicinal plant.
