Narrative
DGE-2 is a durum 1E(1A) alien disomic substitution line with 28 chromosomes, 26 derived durum wheat cultivar 'Langdon' and two chromosomes from diploid wheatgrass, Lophopyrum elongatum (Host) A Love (2n = 2x = 14; EE genome). Chromosome 1E in double dose from the wheatgrass replaces the pair of 1A chromosomes of durum. DGE-2 was derived from a cross between the alien 1E disomic addition line DGE-1 (PI 645483) and Langdon disomic substitution line 1D(1A). DGE-2 alien substitution has regular meiosis with 14 bivalents and is fertile. Seed size of DGE-2 is smaller than that of Langdon. Its 100-kernel weight is 2.74 gm compared to 3.20 gm of Langdon and 2.50 gm of DGE-1. Chromosomal status of DGE-2 has been verified by both conventional cytological techniques and fluorescent genomic in situ hybridization. Molecular markers specific to the group-1 chromosomes were used to confirm the substitution of chromosome 1A with 1E. DGE-2 has the high molecular weight glutenin alleles from the durum parent as well as an added allele Glu-E1b from L. elongatum chromosome 1E. The new disomic substitution DGE-2 should be useful for basic and applied research on homoeologous group-1 genes
