Abstract

The aim of this study was to quantify the severity of foliar diseases, yield and its components, in 16 bean genotypes during the rainy season of 2011, in Quevedo, Ecuador. The experimental design used was the randomized complete block (RCBD) with 16 treatments and four replications. Mutual effect of the web blight severity (%), rust and viruses, during stages R5 (preflowering), R6 (flowering) and R7 (pod formation) was estimated. After harvesting, yield components per plant were quantified (pods number, seeds number, number of seeds per pod, grains weight and sterile pods) as well as grain yield (kg ha-1) corrected to 13% of the moisture content. The lines Cf4 0-0-2-1 and EVG-16-08 showed the lowest final severity (phenological stage R7) of foliar diseases (28.3%). Number of pods, grains number and grains weight per plant were determined as important secondary components, showing significant yield regressions (p≤0.01). Cluster analysis clearly distinguished foreign variety FTS Soberano and the line-EVG 16-08, as promising lines with higher production qualities.
