“…The dominant gene Bgp-1 found in Don Silvio conditions normal pod development under severe disease pressure, but appears to require the presence of bgm-1 for expression (Acevedo-Román et al, 2004). A recessive gene conditioning resistance to chlorosis and a dominant gene conditioning normal pod development were identified in a breeding line with resistance derived from P. coccineus accession G 35172 (Osorno et al, 2003). Allelism tests indicate the two genes are independent of bgm-1, bgm-2, and Bgp-1.…”

Breeding for resistance to biotic and abiotic stresses of global importance in common bean is reviewed with emphasis on development and application of marker-assisted selection (MAS). The implementation and adoption of MAS in breeding for disease resistance is advanced compared to the implementation of MAS for insect and abiotic stress resistance. Highlighted examples of breeding in common bean using molecular markers reveal the role and success of MAS in gene pyramiding, rapidly deploying resistance genes via marker-assisted backcrossing, enabling simpler detection and selection of resistance genes in absence of the pathogen, and contributing to simplified breeding of complex traits by detection and indirect selection of quantitative trait loci (QTL) with major effects. The current status of MAS in breeding for resistance to angular leaf spot, anthracnose, Bean common mosaic and Bean common mosaic necrosis viruses, Beet curly top virus, Bean golden yellow mosaic virus, common bacterial blight, halo bacterial blight, rust, root rots, and white mold is reviewed in detail. Cumulative mapping of disease resistance traits has revealed new resistance gene clusters while adding to others, and reinforces the co-location of QTL conditioning resistance with specific resistance genes and defense-related genes. Breeding for resistance to insect pests is updated for bean pod weevil (Apion), bruchid seed weevils, leafhopper, thrips, bean fly, and whitefly, including the use of arcelin proteins as selectable markers for resistance to bruchid seed weevils. Breeding for resistance to abiotic stresses concentrates on drought, low soil phosphorus, and improved symbiotic nitrogen fixation. The combination of root growth and morphology traits, phosphorus uptake mechanisms, root acid exudation, and other traits in alleviating phosphorus deficiency, and identification of numerous QTL of relatively minor effect associated with each trait, reveals the complexity to be addressed in breeding for abiotic stress resistance in common bean.

“…Results from a survey conducted in 2001 found 41-46% of bean farmers in two principal bean-producing regions of Honduras to have adopted BGYMV resistant bean varieties (Mather et al 2003). The incidence of BGYMV in Puerto Rico decreased drastically after the release of resistant cultivars (Osorno et al 2007). …”

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.

“…Accessions of P. coccineus have been found resistant to several other bean diseases, including angular leaf spot (8,17,31), ascochyta blight (34), anthracnose (16,35), white mold (1,13,19), Eusarium root rot (47), Bean golden yellow mosaic virus (27), common bacterial blight (11,20,28.48), and web blight (9,18,48). In some cases, these sources of resistance have been successfully introgressed from P. coccineus into P. vulgaris (37).…”

Uromyces appendiculatus in Honduras: Pathogen Diversity and Host Resistance Screening

Acevedo, M., Steadman, J. R., and Rosas, J. C. 2013. Uromyces appendiculatus in Honduras: Pathogen diversity and host resistance screening Plant Dis. 97:652-661.Bean rust, caused by the fungus Uromyces appendiculatus, is a major constraint for common bean production worldwide. Virulence of U. appendiculatus collected from wild and cultivated Phaseotus spp. was examined in 28 locations across Honduras. Host accessions representing wild and domesticated Phaseolus spp. collected at the same sampling locations were evaluated for resistance against U. appendiculatus. In total, 91 pathotypes were identified from 385 U. appendiculatus isolates according to their virulence on each of the 12 host differentials. No significant difference in pathogen total virulence, measured as the mean disease score, was found between locations. However, significant differences were found in pathotype virulence among isolates collected from different Phaseolus spp. within a location. Moreover, when locations were compared on the basis of pathotype occurrence and frequency, differences among locations were evident. No two locations had the same pathotype composition. The most common pathotype was virulent on 9 of the 12 differential lines. A high number of resistant accessions were identified in Phaseolus coccineus and P. lunatus. Although most wild P. vulgaris accessions were highly susceptible, rust resistance was observed in P. vulgaris landraces collected from farmer's fields. Thirty-two (52%) of the accessions screened showed intermediate to high levels of resistance and, of those, 16% were P. coccineus accessions. Our findings support the hypothesis that interaction of U. appendiculatus in host populations composed of diverse Phaseolus spp. and genotypes has favored highly diverse and virulent pathotypes, creating a center for virulence diversity of the pathogen in Honduras. The high percentage of interrhediate and highly resistant accessions identified in the present study supports the strategy of collecting plants from the center of diversity of a pathogen or in locations with high incidence of disease and pathogen diversity to maximize the probability of identifying new sources of resistance.Bean rust, caused by the fungus Uromyces appendiculatus, is a major constraint for common bean production around the world. U. appendiculatus epidemics have been most serious in tropical and subtropical areas in the Americas and Africa but severe epidemics have also occurred in temperate climates. A high virulence diversity in U. appendiculatus in many geographic regions has been documented (14,21,23,33,39,40,41,44). Despite the high number of virulence patterns described worldwide, two major pathotype groups can be distinguished in {/. appendiculatus. One of the pathotype groups is virulent on common bean cultivars of Andean origin while the second pathotype group is virulent on common bean cultivars of both the Andean gene pool and the Middle American gene pool (2,23). Based on these results, parallel evolution of host and pathogen has been ...
