Web5 ott 2015 · Hordeum bulbosum L., a wild relative of barley (Hordeum vulgare L.), has been considered as a valuable source of genetic diversity for barley improvement. Since the 1990s, a considerable number of barley/H. bulbosum introgression lines (IL)s has been generated, with segments introgressed from H. bulbosum harboring a diverse set of … WebWe studied the mechanism underlying selective elimination of the paternal chromosomes during the development of Hordeum vulgare x H. bulbosum hybrid embryos that is restricted to an early stage of development. In almost all embryos most of the H. bulbosum chromatin undergoes a fast rate of elimination within nine days after pollination.
