Description:
Selected mutations for VRT2 from ethyl methane sulphonate (EMS) mutagenized populations of common
wheat Cadenza (vrt-A2) and Kronos (vrt-B2) population were inter-crossed and then introgressed into
Kronos (PI 576168) by crossing it three times with the non-mutagenized Kronos. Mutations in the A and B
genome homeologs were combined by crossing, and selection of a double homozygous mutant (designated
as null mutant) using marker assisted selection in the F2 progeny.
