The records in this notebook continue the sequence for the 1906 sweet pea experiments documented in notebook [MS Add.10161/1/5/9]. Records are paginated 301-390; there is then a title page 'Farm 1906' [page 390v] followed by records paginated 400-476. After this there is a run of blank pages. At the back of the notebook is a set of maps showing the layout of the plant beds [pp iv-vii].

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 and whether hooded or not [see, for example, the detailed notes on pp 337v-338, 345r and 349v].

There is a photograph on [page 334v], dated 16 August 1906 and captioned on the back, showing a portion of a row 10 feet long containing 29 fertile and 11 sterile plants. The plant on [page 433v] is marked ‘v. important’.
