Highly fertile F hybrids were made between Triticum turgidum L. ssp. turgidum (2n = 28, AABB) and Aegilops tauschii Coss. (2n = 14, DD) without embryo rescue and hormone treatment. The F1 plants had an average seed set of 25%. Approximately 96% of the F2 seeds were able to germinate normally and about 67% of the F2 plants were spontaneous amphidiploid (2n = 42,AABBDD). Cytological analysis of male gametogenesis ofthe F1 plants showed that meiotic restitution is responsible for the high fertility. A mitosis-like meiosis led to meiotic restitution at either of the two meiotic divisions resulting in unreduced gametes. Test crosses of the T. t. turgidum–Ae. tauschii amphidiploid with Ae.variabilis and rye suggested that the mitosis-like meiosis is controlled by one or more nuclear genes that continue to function in derived lines. This discovery indicates a potential application of such genes in producing double haploids.
