Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans. Repositório Alice
BASSI, D.; BRIÑEZ, B.; ROSA, J. S.; OBLESSUC, P. R.; ALMEIDA, C. P. de; NUCCI, S. M.; SILVA, L. C. D. da; CHIORATO, A. F.; VIANELLO, R. P.; CAMARGO, L. E. A.; BLAIR, M. W.; BENCHIMOL-REIS, L. L..
Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 recombinant inbred lines. Phenotypic evaluations were performed in the greenhouse to identify quantitative trait loci (QTLs) associated with resistance by means of the composite interval mapping analysis. Four QTLs were identified for ALS resistance. The QTL ALS11AS, linked on the SNP BAR 5054, mapped on chromosome Pv11, showed the greatest effect (R2 = 26.5%) on ALS phenotypic variance. ForPWMresistance, two QTLs...

Mapping QTLs for drought tolerance in a SEA 5 x AND 277 common bean cross with SSRs and SNP markers. Repositório Alice
BRIÑEZ, B.; PERSEGUINI, J. M. K. C.; ROSA, J. S.; BASSI, D.; GONÇALVES, J. G. R.; ALMEIDA, C.; PAULINO, J. F. de C.; BLAIR, M. W.; CHIORATTO, A. F.; CARBONELL, S. A. M.; VALDISSER, P. A. M. R.; VIANELLO, R. P.; BENCHIMOL-REIS, L. L..
The common bean is characterized by high sensitivity to drought and low productivity. Breeding for drought resistance in this species involves genes of different genetic groups. In this work, we used a SEA 5 x AND 277 cross to map quantitative trait loci associated with drought tolerance in order to assess the factors that determine the magnitude of drought response in common beans. A total of 438 polymorphic markers were used to genotype the F8 mapping population. Phenotyping was done in two greenhouses, one used to simulate drought and the other to simulate irrigated conditions. Fourteen traits associated with drought tolerance were measured to identify the quantitative trait loci (QTLs). The map was constructed with 331 markers that covered all 11...
