When planting seedlings all crosses are recorded in a notebook, computers crash.
When I plant seedlings each cross is given a simple number beginning with 01
When planted in a box or in the ground the number(mini blind) is placed in the pvc pipe so I can find it when the plants get larger.
When I select a seedling it keeps the same cross # 01 but I add HB01-16 ( HB means hybridizing bed) (01 cross # which is recorded in the note book) (16 is the first year of evaluation)
I also have a photo and information
