Developmental phenotypes of Primula vulgaris Oakleaf. (a) Seedlings from a wild‐type × Oakleaf cross showing wild‐type and mutant phenotypes, arrows indicate Oakleaf seedlings. (b) Leaf from Oakleaf plant. (c) Primula vulgaris Oakleaf mutant showing leaves and flowers. (d) Example of F₁ plant from wild‐type × Oak Leaf cross showing extreme attenuated petals phenotype. (e) Example of F₁ plant from wild‐type × Oakleaf cross showing partially attenuated petals. (f) Example of F₁ plant from wild‐type × Oakleaf cross showing near normal petals. (g) Leaves emerging from an ectopic meristem (indicated by arrow) on the main vein of an Oakleaf leaf. (h) Flower bud (arrow) emerging from an ectopic meristem on the tip of an Oakleaf leaf. (i) Seed capsule (arrow) arising from ectopic flower shown in (h) following pollination. (j) Flower on Hose in Hose – Oakleaf double mutant plant. (k) Flower on Jack in the Green – Oakleaf double mutant plant. (l) Flower on Hose in Hose – Jack in the Green – Oakleaf triple mutant plant. Bars, 1 cm.
