Sources and inheritance of resistance to halo‐blight of Phaseolus beans

Abstract

Forty-three accessions of Phaseolus vulgaris and four of P. coccineus were classified on the basis of the reaction of their primary leaves and pods to inoculation with races 1 and 2 of the pathogen Pseudomonas phaseolicola. Four groups were recognised, (I) highly resistant to race 1 only, (2) resistant to both races, (3) slightly resistant to both races or (4) susceptible to both races. Race 1 resistance was present in a number of accessions (e.g. Red Mexican U13, Rona, Cornell 42-242). Resistance to race 1 and 2 was present in PI 150414, GN Nebraska No. 1 sel. 27, OSU 10183 and other accessions with PI 150414 in their parentage.Studies on the inheritance of resistance in Red Mexican UT3 and PI 150414 were made in crosses with various susceptible bean cultivars. A single dominant factor was responsible for race 1 resistance in Red Mexican UI3. The resistance factor in PI 150414 to races 1 and 2 behaved as a recessive in crosses with Cascade and Seafarer but was partially dominant in crosses with Gallatin 50. These findings suggest that genetic background can influence the expression of the resistance factor from PI 150414 and largely reconcile the conflicting evidence of previous investigators.

75 years of breeding pinto bean for resistance to diseases in the United States

“…Nonetheless, halo blight is common in humid pinto bean production regions in Colorado, Nebraska, Michigan, Minnesota, and North Dakota. Both race-specific and non-specific major gene resistances have been available (Coyne et al 1967;Taylor et al 1978Taylor et al , 1996. Moreover, only recently a resistant pinto cultivar (US 14) and its inheritance were reported for the most virulent pathogen Race 6 (Duncan et al 2008).…”

Introgressing resistance to bacterial and viral diseases from the middle American to Andean common bean

“…a dominant mode of inheritance as reported by Urrea et al (1999) for the common bacterial and by Taylor et al (1978) for halo blight. Nonetheless, this deprived us from selection within the F 1 despite the fact that ZARA I was a multiple-parent inter-gene pool cross.…”

“…The method described by Taylor et al (1978) was used in the greenhouse inoculation of F 1 and F 3 for halo blight at Valladolid, Spain. A mixture of the Psp isolates SITA528 and SITA812 was used to inoculate the primary leaf.…”

“…They also possess more favorable alleles and QTL imparting higher level of resistance to drought (Terán & Singh, 2002), BCMV and Bean common mosaic necrosis virus (BCMNV, a potyvirus) (Drijfhout, 1978), common bacterial blight (Singh & Muñoz, 1999), halo blight (Taylor et al, 1978), and other biotic and abiotic stresses (see review by Singh, 2001). Moreover, the genetic base of both Andean and Middle American cultivars within market classes is very narrow (Miklas, 2000).…”

Common Bean ( Phaseolus vulgaris L.)

“…Resistance to halo bacterial blight is inherited by a single dominant or recessive allele (Asensio et al, 1993;Taylor et al, 1978). Race-specific and nonspecific resistance to halo blight in common bean is found.…”
