Comparación de seis variedades de frijol en el rendimiento y sus componentes en Chaltura, Imbabura, Ecuador

In the northern Ecuador, the beans ( Phaseolus vulgaris L.) productivity is low due to varieties little adapted to local conditions. The objective of this study was to evaluate six pure bean varieties collected in the Ecuador’s Andes mountains and compare to the Rosado bolon variety, which is highly used by local farmers. Was evaluated the plant vigor, grain colour, flower colour, presence of pests, 100-grain weight, seed moisture, number of pods per plant, number of seeds per pod, number of grains per plant, number of leaves per plant and plant height. A single-plot design was used. The results showed that the grain yield was correlated with the varieties Toro rojo, Rosado bolon and Paragachi. Number of grains per pod and number of pods per plant were highly correlated with yield. Finally, was observed the presence of Bean common mosaic virus (BCMV), while the insect that had the greatest presence was the Trip ( Caliothrips phaseoli (Hood)).
