In the past 12-13 years, in order to increase production and income, Colombia, a big coffee country, has rewarded improved new varieties in the form of national policies (high fruit rate, strong resistance to diseases and insect pests, and low planting costs). It is even semi-mandatory to cut down old varieties and change them to improved varieties in some areas. Under such conditions, in order to protect the old varieties with small yield, easy to diseases and insect pests, but high quality, the manor has been firmly rejected.
