| This work evaluated the effect of genotype by environment interaction in Andean common bean lines with white grains, in Central Southern Brazil, to identify lines with high agronomic performance, stability and adaptability, aiming to meet domestic demand and to increase the Brazilian participation in the foreign market of common bean. Nineteen trials with twelve Andean lines were conducted in 2007, 2008 and 2009, in Central Southern Brazil. Grain yield and other agronomic traits were evaluated. Data were subjected to analysis of variance and of adaptability/stability using Annicchiarico and modified AMMI methods. Significant differences were found between lines for all traits evaluated. Genotype by environment interaction was important for lines with... |

| ABSTRACT: Despite important biotic stresses to common bean, Anthracnose (ANT) and Angular Leaf Spot (ALS) can cause losses of up to 80 % and occur in more than 60 countries around the world. Genetic resistance is the most sustainable strategy to manage these diseases. Thus, we aimed to (1) identify new SNP markers associated with ALS and ANT resistance loci in elite common bean lines, and (2) provide a functional characterization of the DNA sequences containing the identified SNP markers. We evaluated 60 inbred lines, under field conditions, which represent the elite germplasm developed by the Embrapa common bean breeding program across 22 years, in terms of severity of the ALS and ANT. The lines were genotyped with 5,398 SNPs. Then, a Mixed Linear Model... |

| ABSTRACT: More efficient strains of Rhizobium have been selected for use in common bean. However, little effort was made with lines selection. The main goals of this research were to verify the presence of interaction involving common bean elite lines utilizing Nitrogen fertilization and Rhizobium inoculation for grain yield and to identify lines with superior yields utilizing biological nitrogen fixation. Eight field trials were conducted at four location-years in Brazilian savanna, using randomized complete blocks design with three replications. Each trial was composed of 17 carioca elite lines. Every two tests in each location were planted side by side, one with mineral nitrogen fertilization (90kg) and the other one with inoculation with Rhizobium... |
