Abstract:
In ovules of cultural sunflower (Helianthus annuus L.) CMS line VIR 116, which were pollinated by wild perennial specie H. occidentalis, the integumentary embryos have been revealed. They are found out at 7-9 days after pollination in embryo sacs where there was no normal fertilization. The integumentary embryos arise from somatic cells of a parent organism and their occurrence can be one of the reasons matroclinal inheritances at interspecific hybrids.
