Summary

The isolation of viable egg cells of rape (Brassica napus L.) has been achieved from microdissected ovules. The non-gametic cells of the embryo sac, synergids and central cells have also been isolated. Their morphology corresponded to that of these cells in situ, making a discrimination from isolated sporophytic cells possible. Two hours after isolation the egg cells were still viable. Viable egg cells have been reproducibly isolated with afrequency of 25% per dissected ovule.
