| Newly synthesized amphidiploids from the hybrids, Emmer
wheats x Aegilops squarrosa varieties
M. TANAKA Laboratory of Genetics, Kyoto University, Kyoto, Japan Seed-fertility of F1 hybrids (3x) between Emmer wheats and 3 varieties of Ae. squarrosa are shown in Table 1. The seeds were produced by the union of unreduced gametes. From these results, it became clear that in the following combinations, T. persicum x Ae. squarrosa var. Meyeri or T. persicum x Ae. squarrosa var. strangulata, abundant seed grains due to restitution are produced. This fact may indicate that these combinations would have more posibilities than other combinations to be the origin of 6x wheats. |
