Admin History: Ralph Riley (1924 - 1999) was a leading figure in crop genetics and biotechnology. He entered Sheffield University in 1947 and, after his undergraduate degree in Botany and studied for a PhD with John Thoday. Two years into his PhD he was recruited by Douglas Bell, then the Director of the Plant Breeding Institute at Cambridge, to study the introduction of useful variation into the wheat crop from its wild relatives, and to take wheat breeding on to the next step. Two years later in 1954 Riley became the founder and first Head of the Cytogenetics Department at the PBI. In 1957 he discovered the Ph gene which controlled pairing between the chromosomes of wheat and wild relatives of wheat and was able to devise and demonstrate the cytogenetic ways by which useful genes, such as those that confer novel disease resistances, could be transferred into wheat from a host of wild species. This discovery of the Ph gene allowed the first "genetic engineering" and his methods have since been used around the world in all major cereal breeding programmes. Director of the PBI, 1972 -1978
