Figure 2.

Selection differentials on age at flowering (AAF; 95%CI) in three populations of Brassica rapa differing in association between AAF and Julian date of flowering (JDF). Differentials estimated using via (a) flowering and seed production schedules (n = 56 plants per population), (b) genetic paternity analysis (n = 56 parents + ∼500 offspring) and (c) comparison of mean AAF in parental and offspring generations (n = 784 parents + 784 offspring per population; offspring sampled uniformly across mothers).
