Description:
Induced mutant CAD1995 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-A3. The resulting miR156-resistant allele (rSPL-A3) 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. BC2F4 seeds homozygous for the mutation are deposited here.
