Two metrics widely used to measure the overall impact of breeding programs are: (i) adoption of modern varieties as a percentage of the total area under the crop, and (ii) the area‐weighted varietal age of a crop in a particular country or region, estimated as the average time since the release of varieties, weighted by the area across which they are adopted. The graph compares this data for roots tubers and bananas with other crops based on information gathered in 2010 (Walker & Alwang, 2015). The paper provides an update through case studies of varietal change in banana, cassava, potato, sweetpotato and yam.
