[edit] History
The Shirley poppy was created from 1880 onwards by the Reverend William Wilks, vicar of the parish of Shirley in England. Wilks found in a corner of his garden where it adjoined arable fields, a variant of the field poppy that had a narrow white border around the petals. By careful selection and hybridization over many years he obtained a strain of poppies ranging in colour from white and pale lilac to pink and red, and unlike the wild poppies these had no dark blotches at the base of the petals. Further selection has given rise to semi-double and double forms, as well as flowers with a ring of contrasting colour around the edge: the picotee form.
[edit] Genetics of Shirley Poppies
The striking example of deviation from a wild type under artificial selection provided by the Shirley poppy attracted the attention of pioneer geneticists and biometricians. Among these was Karl Pearson who used the Shirley poppy to study his ideas of homotyposis, which he defined as “the quantitative degree of resemblance to be found on the average between the like parts of organisms” [1] [2]
