GCP links basic science with applied research through a broad network of plant scientists from diverse backgrounds, working at CGIAR Centres, in academia and regional and country research programmes. This network generates knowledge, explores new allelic diversity and develops practical tools such as molecular markers for desirable traits to increase the efficiency of plant breeding in developing countries. The overall goal is to produce better crop varieties for resource-poor farmers in drought-prone and harsh environments. For a rapid overview on the ABCs of plant breeding, we recommend this five-minute ISF video. It succinctly outlines the work needed and steps to take to develop a new plant variety, and the time and resources that are needed in the process.
