Description:
UC Davis durum wheat advanced lines were crossed to the isogenic durum wheat line 1A.1D 2+12-2/3*WB881 provided by A. Lukaszewski and carrying segments of the D genome from bread wheat. After the initial cross, six backcrosses to the adapted parent for UC1308 and UC1171, and five backcrosses for UC1113 Gpc, were performed, selecting progenies carrying the 2+12 alleles. These lines were then self-pollinated to BC6F3 and BC5F3, respectively, and selected for homozygosity at the 2+12 loci
