“…In a study developed by Lara et al (2014Lara et al ( , 2015, ME1 was found to be located 0.82 and 0.29 cM from a QTL with 71.37 and 0.55% heritability by the straw test and oxalic acid evaluation methods, respectively. This QTL acts to increase resistance to white mold.…”

“…Haggard (2007) identified this marker associated with resistance to white mold by straw test in GL6. By using both the straw test and reaction to oxalic acid, Lara et al (2014Lara et al ( , 2015 used the mapping population obtained from a cross between CNFC 9506 and RP-2 and identified the markers BM184 and BM187 associated with the most significant QTL, with high heritability. However, these markers contribute to reduce resistance and are distant from each other at 43.84 cM by the oxalic acid method.…”

ABSTRACT. In this study, we aimed to estimate the relationship between some common bean traits using molecular markers and applying QTL mapping. We used a segregating population derived from a crossing between common bean cultivars, Jalo and Small White, in the Southern State of Minas Gerais. Of F 2 plants, 190 F 2:3 progenies were generated. Phenotypic measures related to the pod and leaf lengths and the 100-grain weight were used. DNA sampling and genotyping with SSR markers were performed in F 2 plants and the pure parental. The 190 F 2:3 progenies and six controls were evaluated through a 14 x 14-m triple lattice. Adjusted means of evaluations related to F 2:3 were used in QTL mapping using Bayesian moving away method. Significant genetic differences were detected between parents and between progenies for all traits. The heritability estimates were 58.89, 79.39, and 50.37% for leaf length, 100-grain weight, and pod length, respectively. Genetic and phenotypic correlations were significant and ranged from 0.44 to 0.74, which indicated an association between leaf length, 100-grain weight, and pod length traits. Significant genetic correlations between the three morpho-agronomic traits may be due to associations between QTL for different traits. The most promising candidate marker was the BMD17 for leaf length; BM143 for 100-grain weight; X57211 and PVBR118 for pod length. The most promising markers, which might be used for indirect selection for all three traits, are simultaneously X57211 and BM197.

“…In addition to the complexity of the white mold resistance, wide variability of S. sclerotiorum isolates make difficult the selection of resistant genotypes (CARNEIRO et al, 2011;PASCUAL et al, 2010;SCHWARTZ and SINGH, 2013;SILVA et al, 2014). Although, some papers report a small variability of this pathogen in Brazil (LEHNER et al, 2015;LEHNER et al, 2016 a).…”

“…Therefore, some researchers have been working to increase the level of white mold resistance in common bean cultivars (LYON et al 1987;SINGH, 2009;SINGH, 2010;LEITE et al, 2016). It has already been identified lines with similar resistance to non-adapted sources in Brazil (GONÇALVES; SANTOS, 2010;LEITE et al, 2016;SILVA et al, 2014).…”

ABSTRACT:The objectives of this study were to verify the resistance of common bean lines derived from recurrent selection for white mold resistance and to identify those more stable to different isolates; to compare the aggressiveness of different Sclerotinia sclerotiorum isolates; and to verify isolates x lines interaction. Fifteen common bean lines were evaluated, twelve derived from recurrent selection for white mold resistance, one non-adapted source of resistance (Cornell 605), one moderately resistant and adapted (VC-16) and one susceptible to white mold (Corujinha). Ten isolates were used to inoculate the common bean lines through the straw test. A total of ten experiments were performed, one for each isolate. The randomized complete block design with three replications was used in each experiment. Each plot had five plants inoculated in two main branches, therefore the plot data was the average of the ten evaluations through a scale of nine grades. Diallel analysis were used to estimate the general reaction capacity (lines) and general aggressiveness capacity (isolates) to measure the resistance to white mold and the aggressiveness of the isolates, respectively. The GGE biplot analysis was used to group the common bean lines based on their resistance alleles and identify those more instable to the isolates. The resistance of the lines P4 and P10 was similar to Cornell 605, and they had stable reaction to different isolates and "Carioca" grain type. The lines of the advanced cycles of recurrent selection accumulated more favorable alleles than those of the first cycles, confirming the efficiency of the recurrent selection to increase white mold resistance in common bean. In addition, it was identified more aggressive isolates, UFLA 109 and UFLA 116, and a small magnitude of isolates x lines interaction, indicating a predominance of the horizontal resistance of the lines.
