Research Abstract

1. A large variability was found in photosynthetic capacity and respiratory characteristics in nuclar cytoplasmic hybrids of common wheat with cytoplasms of common wheat and its related species. Photosynthetic capacity differed more than 30% among the hybrids, while higer capacity was accompanied by incompatibility, resulting in the reduction of plant vigor of the hydrids. The activities of cytochrome path, cytochrome c oxidase and alternative path differed significantly among the hybrids. The cytochrome c oxidase activity was markedly high in hybrids with cytoplasms causing the reduction of growth vigor.
2. Cytoplasms of two Agropyron species caused marked reduction in growth vigor and male fertilitly when combined with common wheat nucleus, while Agropyron telocentric chromosmes restored normal growth vigor and male fertility. The incompatibility between Agropyron cytoplasms and common wheat nucleus was expressed as aberrant mitochondrial function.
3. Study of chloroplast and mitochondrial DNAs showed that the genetic distances between cytoplasmic genomes of common wheat and the two Agropyron species were nearly the same as that between common wheat and Haynaldia villosa. The cytoplasmic genomes of the two Agropyron species differed significantly.
4. Physical maps of chloroplast DNAs of the two Agropyron species and Haynaldia villosa were constructed and photosynthesis-related genes were located on the maps.
