progress made on cereal breeding during the last 30 years. Against this background, technical discussions focused on hybrid rice breeding, distant hybridization, modified bulk population methods, mutation breeding, and finally on innovative approaches such as tissue culture. The potential of these methods and techniques is great. The.

Based on these materials, and the experience of hybrid rice scientists from China and IRRI, this training manual on the two-line hybrid breeding method has been prepared, which expands upon the hybrid rice breeding manual published earlier by IRRI.
