In intergeneric and interspecific crossing frequently occurs inhibition in the development of <hybrid proembryos> as a result of <endosperm degeneration>. Hence the necessity of in vitro culture of immature embryos. The paper presents attempts to obtain wheat plants through the culture of ovules isolated 1-4 days after pollination and 5-9 day embryos. The medium B5 without 2,4-D wads applied. Plants were obtained from the ovules and 7-9 day embryos, whereas 5-6 day embryos gave no plants. All obtained plants developed directly from embryos; no callus formation was observed.
