Descriptive statistics for diverse traits in population 1 and 2.

Population 1 represents the Col-hybrid population including its associated parental lines, whereas population 2 represents the Ler-hybrid population including its associated parental lines. Abbreviations used: AVG, population average; SD, standard deviation; LA, projected leaf area in cm2 17 days after sowing; FT, flowering time in days after sowing of opening of first flower; HT, height of the inflorescence in cm; MSB, main stem branching in number of branches originated on the main stem; RB, rosette branching in number of branches originated from the base of the rosette; SY, seed yield in grams of seeds produced per plant; SW, 1000 seed weight in estimated grams of 1000 seeds; SZ, seed size in μm2*103; NS, an estimation of the number of seeds produced per plant; H2, broad-sense heritability; CVG, coefficient of genetic variation; rs, correlation between expected mid parent values and the actual values as measured in their offspring (Spearman), with associated p-values (p); n.d., not determined.
