Description:
Loss-of-function mutations for FUL-A3 and FUL-B3 were selected from an ethyl methane sulphonate (EMS)
mutagenized Kronos population and were crossed twice with a Kronos line carrying loss-of-function mutations in both
VRN2 homeologs (Distelfeld et al. 2009). Mutations in FUL-A3 and FUL-B3 were combined by crossing using marker
assisted selection, and a FUL-A3 FUL-B3 homozygous mutant was selected in a Kronos vrn2-null background.
