Description

Alexander Gnutikov and co-authors unpick the parentage of a man-made wheat relative bred for hardiness. Their study appeared in 2025. The hybrid, Trititrigia cziczinii, came from crossing bread wheat with a wild wheatgrass, then crossing back to wheat. Using several DNA markers from nucleus and chloroplast, plus deep sequencing of one ribosomal region, the team asked which parent's genome dominates. The main nuclear ribosomal DNA and the chloroplast both came from bread wheat, marking wheat as the mother line.

One outer marker region, though, leaned toward the wheatgrass parent, hinting at reshuffling or mixed sequences in the hybrid. Deep sequencing confirmed wheat-type copies dominate, with a small wheatgrass-like minority. The authors say knowing the true genomic mix guides using this hybrid in breeding.
