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 were detected, PWM2AS and PWM11AS, on Pv2 and Pv11, explaining 7% and 66% of the phenotypic variation, respectively. Both QTLs on Pv11 were mapped on the same genomic region, suggesting that it is a pleiotropic region. The present study resulted in the identification of new markers closely linked to ALS and PWM QTLs, which can be used for marker-assisted selection, fine mapping and positional cloning. |

As seed chemical composition may lead to different responses during drying and other post-harvest operations, the objective of this study was to determine the effect of drying rate (slow and rapid) and the concentration and composition of lipids in the embryo and endosperm tissues of Coffea arabica seeds on desiccation tolerance/sensitivity. The total concentration of lipids and the composition of fatty acids were evaluated in isolated embryos and endosperms, and in whole (intact) seeds. Embryos had a higher total lipid concentration (23%) than endosperm tissue (8%). Linoleic acid was the predominant fatty acid, with concentrations of 48% in the endosperm and 34% in the embryo tissues. Although rapid or slow drying did not change the fatty acid profile in the embryos or endosperms, the palmitic and linoleic acid concentrations varied significantly between the embryo and endosperm. The predominance of linoleic acid in the endosperm supports the hypothesis that the endosperm tissue may be an important source of damage to the seed and may advance seed deterioration. This indicates that unsaturated fatty acids may have a greater effect on sensitivity to desiccation than the percentage of total lipids. |
