Genotypic and Phenotypic Characterization of Two Triticum aestivum L.—Dasypyrum villosum Translocations Lines in the Same Wheat Genetic Background

A wheat 660K chip was used to genotype two wheat-Dasypyrum villosum 6V#4S.6DL and 6V#2S.6AL translocation lines (A303 B303) their common recurrent parent Wan7107. The results showed that these three have similar characteristics of base composition except for the chromosomes. alien chromosomes fewer homozygous more heterozygous genotypes with invalid probes. Distributions SNPs between Wan7107 were mainly dense on regions 6AS or 6DS as expected, but unexpectedly also near telomere 2BS, some other Meanwhile, A303 B303 99.44% 98.81% identical Wan7107, respectively. Under same genetic background, different reactions Blumeria graminis f. sp. tritici (Bgt) strains powdery mildew. Both higher grain weight plant height, has spikelets compared These provide us a new insight into genomic variation backcross generation parent, which is valuable information understanding relationship 6VS chromosome D. well application potential arms.
