“…Some white mold resistances of Andean (e.g., Don Timoteo, Kaboon, PC 50, PI 313850, Xana) and Middle American (e.g., AB 136, ICA Pijao) common bean (Mkwaila et al, 2011; Park et el., 2001; Pascual et al, 2010; Singh et al, 2012; Soule et al, 2011) and wild bean (e.g., PI 318695) (Mkwaila et al, 2011; Terpstra and Kelly, 2008) and those introgressed from the Phaseolus species of the secondary gene pool (e.g., I9365‐31, VCW 54, VRW 32) (Miklas et al, 1998; Singh et al, 2009a, 2009b, 2012) have not yet been systematically pyramided into common bean genotypes, and their usefulness has not been tested against different pathogenic isolates of S. sclerotiorum across production environments. Therefore, concerted efforts must be made to systematically pyramid white mold resistance and avoidance traits from Phaseolus species and introgress the highest levels of stable resistance into popular cultivars.…”

“…Partial physiological white mold resistance has been reported in small-seeded Middle American and largeseeded Andean common bean, wild bean, and in the Phaseolus species of its secondary gene pool, namely P. coccineus, P. dumosus, and P. costaricensis (Adams et al, 1973;Gilmore et al, 2002;Grafton et al, 2002;Hunter et al, 1982;Maxwell et al, 2007;Middleton et al, 1995;Miklas et al, 1992aMiklas et al, , 1999Mkwaila et al, 2011;Pascual et al, 2010;Schwartz et al, 2006;Singh et al, 2009aSingh et al, , 2009bSingh et al, , 2012Steadman et al, 2001;Terpstra and Kelly, 2008;Tu and Beversdorf, 1982).

“…Hunter et al (1982) reported a group of F 5 breeding lines and Miklas et al (1998) reported four breeding lines, namely I9365-3, I9365-5, I9365-31, and 92BG-7, derived from P. vulgaris × P. coccineus interspecific populations that possessed moderate to high levels of white mold resistance. Singh et al (2009aSingh et al ( , 2009b developed white mold resistant interspecific breeding lines VCW 54 and VCW 55 by congruity backcrossing between a tropical small-seeded black common bean cultivar ICA Pijao and P. coccineus accession G 35172. VCW 54 has a high level of resistance and VCW 55 has an intermediate level of resistance.…”

Breeding Common Bean for Resistance to White Mold: A Review

Under favorable weather conditions white mold causes 100% loss of yield and quality of susceptible common bean (Phaseolus vulgaris L.) cultivars. The disease is endemic and widespread in North and South American countries including the United States, Canada, Argentina, and Brazil. Our objective was to review progress achieved in identifying sources of resistance in Phaseolus species, genetics, and breeding for resistance to white mold. We also describe an integrated genetic improvement strategy for resistance to the pathogen with germplasm enhancement and cultivar development using multiple‐parent crosses and gamete selection methods of breeding. Substantial progress has been made in understanding pathogenic variation in the white mold fungus, developing screening methods, identifying sources of resistant germplasm, genetics of resistance, and introgressing resistance from the secondary gene pool, and breeding for resistance to white mold. Also, molecular marker‐assisted selection for partial resistance is practiced. However, development of white mold resistant common bean cultivars in most market classes has been slow and localized. Breeding strategies for simultaneous and integrated genetic improvement of qualitatively and quantitatively inherited resistances to white mold and cultivar development are briefly described.

“…Most known sources of resistance to white mold are of Andean origin, or from a secondary gene pool, such as P. coccineus L. (Singh et al, 2009). It is important to identify sources of resistance in the Mesoamerican gene pool that are adapted to crop conditions in Brazilian soils and are commercially acceptable.…”

Expression and validation of PvPGIP genes for resistance to white mold (Sclerotinia sclerotiorum) in common beans (Phaseolus vulgaris L.)

et al. 2016

ABSTRACT. The interaction between polygalacturonase-inhibiting proteins (PGIPs), produced by plants, and endopolygalacturonases (PGs), produced by fungi, limits the destructive potential of PGs and can trigger plant defense responses. This study aimed to i) investigate variation in the expression of different common bean (Phaseolus vulgaris L.) genotypes and its relationship with resistance to white mold (Sclerotinia sclerotiorum); ii) determine the expression levels of PvPGIP genes at different time points after inoculation with white mold; and iii) investigate differences in PvPGIP gene expression between two white mold isolates with different levels of aggressiveness. Four bean lines were analyzed, including two lines from a recurrent selection for white mold (50/5 and 84/6), one resistant line that was not adapted to Brazilian conditions (Cornell 605), and one susceptible line (Corujinha). Gene expression was investigated at 0, 1, 2, 3, and 5 days after inoculation. The isolate UFLA 03 caused no significant difference in the relative expression of any gene examined, and was inefficient in discriminating among the genotypes. For the isolate UFLA 116, all of the genes were differentially expressed, as they were associated with resistance to white mold, and the expressions increased until the third day after inoculation. The 50/5 line was not significantly different from the Corujinha line for all of the genes analyzed. However, this line had a resistance level that was similar to that of Cornell 605, according to the straw test. Therefore, the incorporation of PvPGIP genes can increase the resistance of lines derived from recurrent selection.

“…Therefore, during the development of breeding lines we did not consider testing in the field either for plant architectural avoidance traits or for seed yield that required considerably larger quantities of seed (and therefore would have delayed the field tests and development of the three BL) than the tests in the greenhouse. Moreover, white mold disease in the field in dry and warm summer conditions in Idaho tend to be less severe and less reliable than the greenhouse tests (Singh et al, 2009a,b). Furthermore, under severe disease pressure plant architectural avoidance was inadequate to combat white mold in the field (Miklas et al, 2013).…”

Large‐seeded common bean (Phaseolus vulgaris L.) breeding lines (BL) PRA152 (Reg. No. GP‐304, PI 680637), PRA154 (Reg. No. GP‐302, PI 680635), and PRA155 (Reg. No. GP‐303, PI 680636) were jointly developed at the University of Idaho, Kimberly Research and Extension Center and Colorado State University, Fort Collins. The three BL possess the highest levels of broad‐spectrum white mold resistance (mean disease scores ranging from 3.0 to 3.8) than in previously available large‐seeded common bean BL, germplasm accessions, and cultivars to Sclerotinia sclerotiorum (causal agent of white mold disease) isolates ARS12D, ARS14D, ARS14M, ARS15T, CO467, ND710, and NY133. PRA152 was derived from Cornell 501/G 122//A 195/VCW 55, PRA154 was developed from VA 19/M0162//A 195/G 122, and PRA155 was selected from A 195/4/NY6020‐4/92BG‐7///M0162/I9365‐25//‘ICA Bunsi’/G 122 common bean populations. All BL have a determinate upright growth habit Type I. PRA152 has dark greenish gray–colored seeds with average weight of 45.6 g 100 seed−1. PRA154 has beige mottled seeds with 48.0 g 100 seed−1. Seeds of PRA155 are cream with black spots, with 26.9 g 100 seed−1. PRA154 matures in <100 d, and PRA152 and PRA155 require approximately 105 to 110 d from planting to harvest maturity in southern Idaho. White mold resistance from the three BL should be combined with other complementary sources of resistance to breed for yet higher levels and broader spectrum of resistance and/or introgressed into common bean cultivars of different market classes to combat white mold disease in the United States and elsewhere.
