Phenotype
Large rosettes with numerous leaves, leaf margins serrated, late flowering (vernalization at rosette stage may promote earlier flowering), dark -green plants, height= 42-48 cm. Plants did flower after 4 wk vernalization but considerably later than H51. Shindo, et al. (2006). Despite responding to 4 wk of cold, Var-2-6 and Ull-2-5 still flowered late after >6 wk of cold; i.e., the vernalization response was relatively slow.Flowered extremely late after 8 wk vernalization and required at least 14 wk of cold to fully saturate the vernalization requirement. FLC levels decreased during cold treatment but then increased significantly after the plants were returned to 23°C.After 4 wk vernalization, FLC levels had increased (by 30 d after transfer to 23°C) to the same level as nonvernalized plants. After 6 wk of cold, FLC levels were lower than those observed at 4 wk.
