| For many years, the gray leaf spot disease (GLS) caused by the fungus Cercospora zeae-maydis Tehon & Daniels, was not considered an important pathogen of maize (Zea mays, L.) in Brazil. However, the recent adoption of agronomical practices such as no-tillage and cultivation under central pivot irrigation systems increased the incidence and severity to the extent that GLS is now one of the most important diseases of maize. Isolates of C. zeae-maydis can be distinguished by two genetic groups (I and II) based on AFLP markers and on polymorphisms of the ITS and 5.8S rDNA regions. Until now, however, the biological implications of this distinction remain unclear. This study investigated whether isolates from the two genetic groups differ in... |

| 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: During the years 2003 and 2004, four experiments were conducted in the winter season, under irrigation and in the raining season in the experimental area of the Embrapa Cerrados Research Center at Planaltina, Federal District. The objective was to identify cultivars that presented the following characteristics: resistance to diseases, high yield, resistance to lodging, desirable plant height and good market acceptance, to be indicated for cultivation in the Federal District. It was concluded that the cultivar BRS Cometa is indicated for this region, due to its high yield characteristics, resistance to diseases and lodging, excellent cooking qualities and erect type. |
