Methods for production f hybrid rose plantlets from rose somatic embryos

摘要

The invention is directed to methods for producing somatic embryos of Rosa hybrida and obtaining regenerated plantlets therefrom. Somatic embryos may be produced by culturing mature tissue from Rosa hybrida in callus induction medium to induce callus formation and subsequently culturing the induced callus in regeneration medium which is capable of inducing completion of the development of somatic embryos. The availability of somatic embryos and the regenerative capacity of such embryos provides convenient raw material for carrying out current methods of plant transformation, such as ballistic methods of DNA delivery, or Agrobacterium culture.
