Vernalization in wheat II. Genetic variability for the interchangeability of plant age and vernalization duration

Differences in response to vernalization in wheat ( Triticum aestivum null L.) were quantified through controlled environment experiments with 26 lines with diverse geographical origins. Vernalization treatments of 0 to 56 d were applied to plants at their first leaf stage. All plants headed irrespective of duration of vernalization treatment. Vernalization response was assessed through the change of final leaf number (FLN) on the main stem at...
