The intergeneric hybrids of barley (♀) and wheat (♂): F₁ (=Manker l6/Chinese Spring) BC₁ (=M16/2*CS) and BC₂ (=M16/3*CS) were developed. The agronomic characters, reaction to diseases, number of stomata, hairiness of the leaf surface, and chlorophyll and total nitrogen contents of flag leaf were compared with those of their parent, Manker 16 and Chinese Spring. Of the 4,240 florets pollinated, 78 embryos were cultured from which 7 hybrid plants with 2n=28 chromosomes were obtained but those F₁ plants were self sterile. The first backross seeds examined had 49 chromosomes in the embryo. Twenty-four seeds obtainde from the BC₂hybrids (=M16/3*CS), and these BC² hybrids appeared the 46-49 somatic chromosomes. The heading dates of these plants showed a late tendency compared with their parents. However, they grew vigorously and speltoedspike type of wheat. The numbers of stomata on leaf surface were less than that of parents, and chlorophyll content of flag leaf was intermediate. Also those plants were resistant to stem rust and immune to powdery mildew.
