Description:
The induced mutant CAD1033 from the sequenced EMS population of hexaploid wheat Cadenza (Krasileva et al., 2017, PNAS 14:E913) has a mutation in the miR156 target site of SPL-B3. The resulting miR156-resistant allele (rSPL-B3) was crossed to a bridge F2 line derived from the cross between the hexaploid cultivar Insignia and Kronos to avoid hybrid necrosis, and then back-crossed two more times with Kronos.BC3F3 seeds homozygous for the mutation are deposited here.
