Efficiency of each of stages of haploproduction depends on the genotypes of paternal forms, combination of crossings and generation of hybrid. It was concluded the homozigotation drought-resisting hybrids H. vulgare x H. spontaneum F2, 11 lines of doubled haploids were obtained. Thus, all results testify to the real possibility of receipt of new drought-resisting lines of barley with the H. spontaneum as a source ofdrought-resisting on the early stages of breeding. with using of the process androgenesis in vitro Product Description popup.authors popup.nrat_date 2020-04-02 Close
