“…The QTL on Pv03 (B3) is associated with disease avoidance traits such as canopy porosity, plant height, stay green stem trait, and maturity . The QTL responsible for white mold avoidance resides in P07863, the highest yielding RIL in the AP630 population that has since been released as the cultivar Eldorado (Kelly et al, 2012). Ex Rico 23 was first identified by Tu and Beversdorf (1982) as a source of avoidance to white mold and has been used subsequently in other QTL studies for white mold (Kolkman and Kelly, 2003).…”

“…Plants develop a dense leaf canopy at flowering that freely lodges, creating a microclimate favorable for disease development under the decumbent plant canopy (Miklas et al, 2013). These include pinto cultivars such as Santa Fe (Kelly et al, 2010), Lariat, and Stampede (Osorno et al, 2010), Eldorado (Kelly et al, 2012), and the private cultivar La Paz that possess different levels of architectural avoidance to white mold.

White mold is a major disease of common bean (Phaseolus vulgaris L.) grown in temperate production areas. The objective of this study was to use single nucleotide polymorphism (SNP) markers from the BARCBean6K_3 BeadChip to identify quantitative trait loci (QTL) associated with traits related to white mold resistance in common bean. A recombinant inbred line (RIL) population from a cross of disease‐tolerant pinto line AN‐37 and disease‐susceptible line P02630 was evaluated in Michigan for 4 yr under white mold pressure. Traits evaluated included disease incidence, the numbers of days to flower and to maturity, canopy height, lodging, seed yield, and 100‐seed weight. A linkage map of the RIL population spanning 1499 cM was constructed using 447 SNP markers. The map covered all 11 bean chromosomes with an average distance of 3.6 cM between markers. A total of 13 QTL for agronomic and disease traits were consistently identified in different years. A major QTL WM3.1AN associated with white mold avoidance was validated on chromosome Pv03. The QTL is associated with disease avoidance traits such as canopy porosity, plant height, stay green stem trait, and maturity. Quantitative trait loci for maturity and canopy height also mapped to the same genomic region on Pv03. Finding strong associations between maturity, lodging, canopy height, and disease incidence offers alternative strategies to improve levels of white mold avoidance over greenhouse screening. The validation of the WM3.1AN, AP630 QTL for white mold avoidance should provide bean breeders with the opportunity to introgress avoidance traits into their germplasm.

“…With regard to the common bean (Phaseolus vulgaris L.), breeding for white mold resistance has advanced recently, especially in the United States, where several studies on the genetic mechanisms of resistance and breeding strategies have been carried out (Terán and Singh, 2009;Terán and Singh, 2010;Singh et al, 2014;Viteri and Singh, 2015) and a number of partially resistant lines have been released (Griffiths, 2009;Kelly et al, 2012;Miklas et al, 2014).…”

White mold caused by the fungus Sclerotinia sclerotiorum is the most yield-limiting disease of common bean in Brazil. To date, there has been no commercial cultivar resistant to this disease. In a greenhouse we evaluated white mold resistance sources (Cornell 605, A195 and G122) against eight isolates of S. sclerotiorum from five Brazilian states. A Brazilian cultivar (BRSMG Madrepérola) and a susceptible check (Beryl) were used as control. Treatments were arranged in factorial combinations (5 × 8) in a completely random design with four replicates.Disease severity was assessed on a rating scale of 1-to-9 together with lesion length, which was used to determine an area under the disease progress curve (AUDPC). Polymorphisms detected in ten microsatellite loci were used to assess variability between the isolates. Each isolate was a distinct haplotype; they formed a genetic tree with two clusters. One cluster was formed by three isolates collected from the states of Minas Gerais and São Paulo (southeastern); the others, by isolates from Paraná, Santa Catarina (southern), Goiás (Mid-western), and again, Minas Gerais.Genotype × isolate interaction was significant. In general, Beryl was more susceptible than BRSMG Madrepérola. Considering the AUDPC and/or the white mold reaction score, Cornell 605 exhibited more physiological resistance than BRSMG Madrepérola to seven isolates, A195 to five isolates, and G122 to two isolates. Our results suggest that Cornell 605 is the best source of resistance to white mold for the southern region, whereas Cornell 605 and A195 are somewhat superior to G122 for the southeastern and mid-western regions.

“…But in a practical cultivar development program these could also be of significant value for slowing disease development and reducing fungicide usage. Thus, it is necessary to combine the above method of greenhouse screening with simultaneous selection for seed yield and avoidance traits under white mold pressure in the field (Ender et al, 2008;Kelly et al, 2012;Kolkman and Kelly, 2003;Miklas et al, 2012Miklas et al, , 2013Mkwaila et al, 2011). For that region, it may be prudent to use intensive greenhouse screenings and selection similar to this study for development of cultivars with high levels of physiological resistance.…”

Introgressing White Mold Resistance from Phaseolus coccineus PI 439534 to Common Pinto Bean

et al. 2014

White mold [caused by Sclerotinia sclerotiorum (Lib.) de Bary] is a devastating disease of common bean (Phaseolus vulgaris L.) in cool‐ to moderate‐temperature and wet‐production regions worldwide. Use of resistant cultivars is crucial for effective and economical white mold control. Partial resistance exists in cultivated and wild common bean and Phaseolus species of the secondary gene pool. The objectives were to (i) develop highly resistant breeding lines (BL) from a recurrent interspecific backcross of common pinto bean ‘UI 320’ with P. coccineus PI 439534, and (ii) compare their response with known sources of resistance. Five pinto BL derived from UI 320 × 2/PI 439534 interspecific backcross population, the two parents, nine known sources of resistance, and susceptible pinto ‘Othello’ were screened in the greenhouse. Sclerotinia sclerotiorum isolates ARS12D and ND710 were used at the University of Idaho, Kimberly, in 2012 and isolates CO467 and NY133 at Colorado State University, Fort Collins, in 2013. All five interspecific pinto BL (VC13‐1, VC13‐3, VC13‐4, VC13‐5, VC13‐6) in Idaho and three (VC13‐4, VC13‐5, VC13‐6) in Colorado exhibited significantly (P ≤ 0.05) higher levels of resistance than PI 439534. Their resistance was either similar to (in Colorado) or higher (in Idaho) than the highest levels available in other interspecific BL (92BG‐7, I9365‐31, VCW 54, VRW 32) derived from the secondary gene pool thus far, as well as medium‐ (USPT‐WM‐1) and small‐ (‘ICA Bunsi’) seeded Middle American and large‐seeded Andean dry (G 122) and green (NY 6020‐4) beans. The effectiveness of the five interspecific pinto BL for controlling white mold with and without fungicides and other disease management strategies should be performed. Genetics of resistance and tagging and mapping of new resistance genes and/or quantitative trait loci should be performed. Also, high levels of resistance from the five interspecific pinto BL should be pyramided across Phaseolus species and/or transferred into cultivars.
