Extended Data Fig. 2: Meiotic pairing of A. tauschii T093 × common wheat AK58 F1 hybrids.

a–c, The averaged univalent (I) and bivalent (II) number in each meiotic cell of A. tauschii T093 (n = 85 cells), common wheat AK58 (n = 50 cells) and their F1 hybrids (n = 72 cells). d, A meiotic cell of A. tauschii T093 × common wheat AK58 F1 hybrids showing seven bivalents and 14 univalents. Arrows represent the bivalents of 1D with 1Dt, and 2D with 2Dt, respectively. Green: oligo-(GAA)10; red: oligo- pTa535-1. Bar = 20 μm. ANPC, average number per cell.
