Among‐population (V_P), among‐family (V_F), and within‐family (V_W) variance components for each vern alization period in each of two experiments (vernalization as imbibed seeds vs. as young plants), genetic variance proportion (V_P + V_F /V_P + V_F + V_W), and proportion of genetic variance due to among‐population variance (V_P/V_P + V_F) for the response variable proportion of plants flowering
