Michael Denis Gale. 25 August 1943—18 July 2009

Abstract Michael (Mike) Gale was an internationally well-known crop geneticist with a career devoted mostly to wheat genetics. However, he also studied rice, maize, pearl millet and fox millet for the benefit of agriculture in developing countries. He brought new knowledge and techniques into plant breeding that made a difference to crop improvement worldwide. Noteworthy is his team's leadership in (i) defining the genetic basis of dwarfism in wheat, the major genetic innovation underlying the previously achieved ‘green revolution’ in wheat production; (ii) expanding knowledge of ‘pre-harvest sprouting’, which occurs in many wheat varieties growing in temperate climates, which reduces their flour quality and value; (iii) developing the first comprehensive genetic maps of wheat based on isozymic and DNA-based molecular markers; and (iv) developing the comparative genetics of grasses based on the conserved order of genes on chromosome segments, consistent with the evolution of the species from a common ancestor. These discoveries had a major impact in plant genetics. His team also provided the worldwide cereal geneticists and breeding communities with technologies and genetic markers that accelerated the development of cereal genetics and facilitated more efficient plant breeding. He made major and influential contributions to international agricultural research, particularly targeted at developing countries, through his participation on international and national committees, including those of the Consultative Group for International Agricultural Research. His contribution helped to drive the international research agenda for crop genetics, plant breeding and plant science generally.
