Breeding and genetic studies of tolerance to several bean (Phaseolus vulgaris L.) bacterial pathogens

Gepts, P.; Miklas, P. N.; and Coyne, D. P., "Tagging and mapping of genes and QTL and molecular marker-assisted selection for traits of economic importance in bean and cowpea" (2003 The bean map is approximately 1200 cM with some 500 markers and an additional 500 markers shared with other bean maps. The cowpea map spans 2670 cM with over 400 markers. In addition to molecular markers, both maps include map locations of defense genes and phenotypic traits for disease and insect resistance, seed size, color and storage proteins, pod color and those traits associated with the domestication syndrome in bean. Since the bean and cowpea maps were developed independently, LGs with the same number probably refer to non-syntenic groups. Map locations of major resistance genes in bean are revealing gene clusters on LGs B1, B4, B7, and B11 for resistance to bean rust, anthracnose, common bacterial blight and white mold. Gene tagging and marker-assisted selection for disease resistance has progressed to a point where the indirect selection for resistance to a number of major diseases is now routine in bean breeding programs both in the US and overseas. #

“…Common bacterial blight is the major seed-borne disease of common bean worldwide (Tarlan et al 2001;Miklas et al 2003), and the best way to manage CBB includes the use of pathogen-free seed (Zanatta et al 2007). In order to control CBB, the use of bean cultivars with genetic tolerance/resistance to the disease is the most practical method (Coyne and Schuster 1974;Yoshii et al 1978) though the availability of CBB-resistant cultivars is limited. In most of the cases, the resistance/tolerance of traditional varieties to CBB is unknown.…”

The cultivation of Fagioli di Sarconi (FS), a pool of traditional varieties protected with the mark PGI (Protected Geographical Indication) cultivated in the National Park of Agri Valley in Basilicata (southern Italy), is limited by common bacterial blight (CBB), caused by the seed-borne bacterium Xanthomonas axonopodis pv. phaseoli (Xap) and X. a. pv. phaseoli var. fuscans (Xapf), whose control is difficult because of the lack of safe bactericides. Hence, studies were undertaken to assess the susceptibility/tolerance of selected varieties toward the pathogens and to develop eco-compatible measures for the disease management. Five FS varieties showed a differential response to inoculations with virulent strains of the pathogens, and hence, two tolerant cultivars were selected for the introgression of CBB resistance characters. Among the main active components of some essential oils, eugenol determined a highly significant reduction of Xap density on bean seeds, though at the higher dosage, the seed germination reduction was observed. These data indicate eugenol as potentially useful for bean seed disinfection from Xapf, though further studies appear necessary. Among 162 bacterial isolates from bean rhizosphere, six caused a clear reduction of lesions size ranging from 30 to 66 % suggesting that induced systemic resistance may be involved in that feature.

“…The development of resistant cultivars is considered to be the most effective method for the control of bacterial wilt of bean (Coyne and Schuster 1974;Hsieh et al 2005). Genetic studies have shown that the susceptible reaction to the orange variant of C. flaccumfaciens pv.…”

Bacterial wilt, caused by Curtobacterium flaccumfaciens pv. flaccumfaciens, is a widespread problem of dry beans on the Canadian prairies and is listed as a quarantine disease by some countries. The development of resistant cultivars is one of the most effective methods for controlling bacterial wilt. Fourteen kidney bean cultivars were screened against the three variants (yellow, orange and purple) of C. flaccumfaciens pv. flaccumfaciens. High levels of resistance to the three variants were observed in the light red kidney bean cultivars AC Litekid, Chinook 2000 and Redkanner as well as the dark red kidney bean cultivars Cabernet and Red Hawk. These five resistant kidney bean cultivars should be useful sources of bacterial wilt resistance in dry bean breeding programs. Neither of the two white kidney bean cultivars tested consistently showed high levels of resistance to all of the color variants of the bacterial wilt pathogen. Key words: Phaseolus vulgaris, kidney bean, bacterial wilt, Curtobacterium flaccumfaciens pv. faccumfaciens, yellow variant, orange variant, purple variant, resistance
