Mendelism: from hybrids and trade to a science.

In this paper I explore the historical context in which news of the rediscovery of Mendel's laws was received in England. This exploration leads me to the Cambridge zoologist, William Bateson, to his exploitation of the prestige and support of the Royal Horticultural Society, and to his interaction with certain of the leading horticultural tradesmen prominent in that society. I argue that the policy of the RHS in the 1890s to promote hybridisation rather than plant collecting was of crucial importance in bringing about a productive symbiosis between Bateson and his circle and the horticultural community. I look for parallels between the aims of the horticulturists and the character of the Mendelian programme as it is represented in Bateson's foundational text: Mendel's Principles of Heredity (1909).
