“…The annual positive impact of this resistance for US apple production is estimated conservatively at $100 million (Norelli et al, 2003;C.T. phaseoli Smith (Dye); Singh and Miklas, 2015] derived from NPGS PGR accessions as conservatively $500 million+. Miklas (personal communication, 2018) estimates the cumulative value to the US common bean (Phaseolus vulgaris L.) industry of disease resistance traits [e.g., resistance to common blight Xanthomonas campestris pv.…”

Humanity's survival depends on crops—the green line standing between us and calamity. To meet ever expanding human needs, crops must become increasingly more productive, mainly through genetic gains that exploit diverse plant genetic resources (PGR), the raw materials for crop breeding. For millennia, PGR have been conserved by individuals, communities, and organizations. These stewards of our agricultural future have been nearly as diverse as the PGR that they have conserved. Their invaluable roles in underpinning the security of global agriculture have largely been underappreciated. Furthermore, the challenges and complexity of successful PGR stewardship have been inadequately recognized. This paper pays tribute to these stewards’ characteristic attributes and their contributions to PGR conservation and sustainable use. It describes the pervasive impacts of PGR on crop agriculture and explains how numerous factors have affected PGR stewardship capacities. Plant genetic resource stewardship involves many different components, which are typically conducted over extended timeframes. Sustained, adequate support for PGR maintenance, a key component, has been the exception rather than the rule. Past and present PGR stewardship successes and challenges furnish numerous lessons for meeting future demands. Such lessons include recognizing the importance to PGR stewardship of: dedicated and diverse PGR stewards, continual and persistent financial support for PGR genebanks and their staffs, protecting crop wild relatives, and safeguarding genebank collections from extreme weather and introduced pests and pathogens. In the future, PGR stewardship might be conducted more frequently and more adequately by multi‐institutional networks enabled by advances in information technology and artificial intelligence.

“…These diseases are one of the major causes of yield reductions in the bean production regions throughout the world (Schwartz and Pastor-Corrales, 1989;Wortmann et al, 1998). MAS has been used recently in the development of improved common bean germplasm in the U.S. (Singh and Miklas, 2015), Canada (Durham et al, 2013), Brazil (Costa et al, 2010;Souza et al, 2014) and Tanzania (Tryphone et al, 2013).…”

Common bean (Phaseolus vulgaris) is a rich source of protein, vitamins, and micronutrients and is an important crop for food security throughout Latin America, Asia, and Africa. Among tropical and subtropical regions of the world, where the majority of beans are grown, yield losses due to the pathogenic fungus Pseudocercospora griseola, causing angular leaf spot (ALS), can be as high as 80%. The strategic use of marker-assisted selection (MAS) to pyramid multiple resistance genes into a single genetic background with preferred morphological and cooking characteristics is being implemented by six research groups throughout East Africa that make up the African Bean Consortium (ABC). Identifying unique markers that are polymorphic among multiple parents is a major source of marker attrition. In this study, an illustration of how 22 DNA sequences physically linked to the Phg-2 ALS resistance locus were identified using the PhaseolusGenes marker database and checked for amplification and polymorphism among 16 ABC breeding parents are given. Only three polymorphic markers could be identified following this procedure; one (g796), showed a polymorphism present only in the ALS resistance donor, Mexico 54. The PCR protocol developed to identify the g796 polymorphism was validated among five laboratories. Furthermore, co-segregation analysis of the marker and ALS resistance phenotype in a population of 100 F 2 individuals from the cross between French bean (that is, green bean) genotype Amy and ALS resistance donor Mexico 54 showed the marker is genetically linked (3 cM) to the Phg-2 locus, in addition to being physically linked. This study suggests that in the near future, genetic resequencing data of diverse common bean accessions, compiled within an easily accessible database, will facilitate identification of markers for MAS, marker/trait association, and candidate gene identification.

“…White‐seeded common bean is also produced on a limited scale in Haiti, the Dominican Republic, Cuba, Nicaragua, Costa Rica, and Panama (Hernández Fonseca and Araya Villalobos, 2009; Voysest, 1983). Bean golden yellow mosaic virus (BGYMV), a whitefly‐transmitted Begomovirus, can cause severe yield losses to beans in the lowlands of Central America and the Caribbean (Singh and Schwartz, 2010). Bean common mosaic necrosis virus (BCMNV) and Bean common mosaic virus (BCMV) are seed‐borne potyviruses that threaten bean production in Central America and the Caribbean (Miklas et al, 2006; Flores‐Estévez et al, 2003).…”

“…Common bacterial blight (CBB), caused by Xanthomonas axonopodis pv. phaseoli (Smith) Vauterin et al, is a major disease of beans in both temperate and tropical bean production regions (Singh and Miklas, 2015; Singh and Schwartz, 2010). Web blight, caused by Rhizoctonia solani J.G.…”

“…Web blight, caused by Rhizoctonia solani J.G. Kühn, is an important bean disease in the humid lowland tropics (Godoy‐Lutz et al, 1996; Singh and Schwartz, 2010). The development and release of dry bean germplasm lines and cultivars with enhanced levels of disease resistance is an important goal of the University of Puerto Rico (UPR) and other dry bean breeding programs in Central America and the Caribbean.…”

‘Bella’ (Reg. No. CV‐321, PI 681720) is a multiple disease–resistant white‐seeded common bean (Phaseolus vulgaris L.) cultivar adapted to the humid tropics developed and released cooperatively by the University of Puerto Rico Agricultural Experiment Station and the USDA‐ARS. Bella combines resistance to Bean common mosaic virus (BCMV), Bean common mosaic necrosis virus (BCMNV), Bean golden yellow mosaic virus (BGYMV), common bacterial blight, and web blight. The performance of Bella was evaluated across 5 yr in eight environments in Puerto Rico. It tolerated higher temperatures and performed well in soils with low fertility. Bella was developed by pedigree selection to the F7 generation based on superior agronomic traits (early maturity, erect plant architecture, and good pod set) and commercial seed type. Marker‐assisted selection was used to identify the presence of the bgm‐1 gene and the SW12 quantitative trait locus for resistance to BGYMV and the I and bc‐3 genes for resistance to BCMV and BCMNV. Greenhouse inoculations were used to confirm the presence of the I and bc‐3 genes and to screen the line for reaction to strains of common bacterial blight. Mean seed yield of Bella was comparable to the check cultivars. Bella produced among the highest yields in the Bean Adaptation to Stress Environments (BASE) trials planted at Isabela, PR. Bella should allow the successful production of common beans in Puerto Rico throughout the year in soils with lower N fertility. It should also be useful as a parent to enhance the virus, common bacterial blight, and web blight resistance of white, small red, and black beans.
