Common bean is an important vegetable which provides carbohydrates, proteins, vitamins and minerals for human nutrition, and is often used as a meat alternative in poor countries. Demand for beans for the domestic market in Bhutan is huge which results in increased imports annually. The ban on bean imports citing pesticide residues further led to imbalance in the market (supply-demand) equilibrium. To diversify the choice of cultivars for increased production and to help stabilize market imbalance, two improved cultivars from Japan were evaluated for yield stability, yield potential, length of growing season, pest/disease tolerance, and market and agronomic traits. Grey pole bean was used as a check variety for the study. The variety Prime Green, followed by Brown Pole is preferred over Grey Pole on a range of crop characteristics such as yield potential, disease/pest tolerance, marketable traits (fibrous [stringy] and fleshiness of the pods), and agronomic traits (germination rate, and days to maturity). All three cultivars evaluated show yield stability.
