Abstract

In order to investigate the possibility of intergeneric hybrid production through artificial crossing between Hordeum spontaneum and Secale this study was done in Research Institute of Forests and Ranglands' Seeds of S. cereale were planted in pots. Before maturity of pollens and  "rr"il, natural pollination, anthers were omitted to emasculate female plants' Pollen grains were gathered from H. spontaneum, then female parents were pollinat-ed with thern. Hybrid seeds were formed, and although they were wrinkled but they showed enough germination ability. The hybrid seeds were planted in pots and obtained plants were morphologically between two parents.The hybrid plants flowered, but because of abnonnality in meiosis devision, seed was not formed. Results therefore, indicated that by artificial crossing itrtergeneric hybrid seeds can be successfully obtained.However special treatments such as colchicine must be applied to get tetraploid fertile intergeneric hybrids.
