HRDC proposes an integrated approach to enhance the value of the available pool of A lines. HRDC will first provide A lines for research and breeding purposes. Members are encouraged to share their results with HRDC on the performance of these lines. For a second time, and based on the members’ evaluation, B lines of top-performing A lines will be made available. With the collective results coming from HRDC members representing agro-climatic conditions across the world, HRDC would focus on such identified A/B couples for further improvement.
