Family = the full-sibling family the seeds were taken from Height = Plant height (mm) Columns D-I = Measures used in the analysis Columns K+ = Other outputs of Lamina not used Walter_Data_Exp2.csv Field performance data for parental ecotypes, and F1 and F4 hybrids. ENV = transplant environment block = experimental block GRID = grid reference each seed was placed in GENO = generation Type = General identify for the cross types of each generation TypeS = More specific identifier (R, Y and P represent the three independent crossing lines in the F4 hybrid) Family = full-sibling family Sire & Dam = Identifiers of the F3 parental generation GE = [binary] emerged yes/no D100 = [binary] alive at day 100 yes/no L10 = [binary] reached seedling establishment (10 leaves) yes/no Bud = [binary] reached maturity (produced a bud) yes/no Columns N-S = number of days to reach each developmental stage
