Sown Area

Common bean (Phaseolus vulgaris L.) is the most important edible grain legume in Ecuador. The Ministry of Agriculture, Cattle Raising, Aquaculture and Fisheries of this country estimated that 71,600 hectares were cultivated in 2012; of the sown area, 53% was dedicated to dry grain and the remaining 47% to fresh grain. Beans are an important source of income for farmers and food for thousands of Ecuadorian families. Crop performance and yield are affected by diseases such as angular leaf spot caused by Pseudocercospora griseola (Sacc.) Ferraris. The best alternative for disease control is to use resistant varieties. However, durability of field resistance will depend on the knowledge of angular leaf spot variability. In Ecuador, detailed and systematic studies on the variability of the angular leaf spot pathogen have not been conducted. For this reason, the pathogenic variability of 21 isolates of angular leaf spot, collected from the provinces of Carchi and Imbabura in the Ecuadorian Andes, was studied. Thirteen different pathotypes were identified, five of them showed compatibility with only the group of Andean differentials and the remaining eight showed compatibility with two groups of differentials (Andean and Mesoamerican). Race 63:0 was the most frequent and race 31:63 was the most virulent. None of the isolates were compatible with differential Cornell 49-242. Therefore, bean breeding lines in Ecuador would benefit by incorporating the Phg-2 resistance gene present in differential Cornell 49-242 .

A homeopatia baseia-se no princípio da cura pelos semelhantes, e na experimentação no indivíduo sadio, doses mínimas e medicamento único. O uso de tratamentos a base de soluções dinamizadas aplicadas em vegetais aumentou nas ultimas décadas, sendo assim necessária a experimentação patogenésica para aplicação de todos os princípios homeopáticos e consolidação da Matéria Vegetal Homeopática. O ensaio patogenésico com plantas de feijão tratadas diariamente via pulverização e irrigação utilizando óleo essencial de Eucalyptus citriodora em diluições (0,5 e 1%) e dinamizados (12 e 30CH) revelaram sintomas externos semelhantes aos provocados por Pseudocercospora griseola, agente causal da mancha angular em feijoeiro. O estudo patogenésico com E. citriodora levanta a possibilidade deste ser utilizado no controle da mancha angular de acordo com o princípio homeopático da cura pela similitude.

The objective of the present study was to assess the genetic potential of inbred carioca common bean families from five populations derived from crossings involving elite lines and a disease-resistant line (Rudá-R), and to assess the efficiency of SCAR molecular markers in selecting plants resistant to anthracnose and angular leaf spot, at the time of bulk formation. Plant architecture, yield and grain type were assessed. Significant effect among families within population was observed, suggesting wide genetic variability for the characters assessed. Twenty-six superior families were selected. The families contained the greatest number of markers, identified by SCAR molecular markers in the F4 generation. Eighteen of these families were resistant to the races 65 and 453 of Colletotrichum lindemuthianum and five were resistant to the race 63.23 of Pseudocercospora griseola. Thus selection assisted by SCAR markers, in the F4 generation, was an important tool in common bean breeding.
