B.oleracea heading date variation
Judith Irwin, Andrew Davis (JIC)
NRP-153

The ability to schedule crop production and control harvest time across the growing season is of critical importance for horticultural crops. In broccoli and cauliflower, differences in harvest time between varieties is due to variation in the requirement for a period of cold (vernalization) to promote flowering. At the John Innes Centre on the Norwich Research Park, we are using mechanistic insights from fundamental studies in Arabidopsis to identify key genetic components controlling heading date (seed head emergence) in the popular related crop, broccoli. The image shows variation in heading date in a mapping population used to map some of these genes.
