Summary of scientific research
Dr. Chang directed his attention to crop improvement and genetic resources conservation. He played a pivotal role in the ‘Green Revolution’ in rice by introducing and incorporating the sd-1 semidwarfing gene from Taiwan which confers high productivity on tropical rices, and supported continuing advances by supplying useful germplasm. He also rescued numerous threatened land races and wild rices through collaborative field collecting and persuading Asian and African nations to deposit their national rice collections for safekeeping in the IRRI Germplasm Center with the guarantee of repatriation, and helped China, the USA, India and Taiwan in designing modern seed preservation banks. In addition, he trained more than a thousand young rice workers from developing nations in rice production, breeding, and germplasm conservation.
