Sweet Pea Notebooks

<p style='text-align: justify;'> Notebook recording Bateson and Punnett's experiments with sweet pea crosses in 1907. Records are paginated 1-187, followed by a long run of blank pages. At the back of the book is a set of notes dated 30 Apr. 1907 pp <a href='' onclick='store.loadPage(247);return false;'>i(v)-ii(r)</a> along with maps showing the layout of the plant beds pp <a href='' onclick='store.loadPage(249);return false;'>ii(v)-vi</a>. The general format of the record is that the parents are recorded as numbers with a superscript or sometimes as a named variety. Since sweet peas can be selfed, some crosses have only a single parent. The date of sowing and the date of planting out are recorded, together with other observations on the plants such as colour, height and petal form. An entry on page <a href='' onclick='store.loadPage(56);return false;'>45v</a> records a bet between Punnett and Bateson, 'RCP bets 10/- shillings these will be reds: WB was not so sure and takes this bet'. The plants on pages <a href='' onclick='store.loadPage(76);return false;'>61v-62r</a> and <a href='' onclick='store.loadPage(156);return false;'>125v-126</a> are marked 'important' or 'v important'. The records on pp <a href='' onclick='store.loadPage(99);return false;'>79v-90</a> and <a href='' onclick='store.loadPage();return false;'>131-180v</a> include a series of tables showing scoring and classification of progeny.
