The Use of Ovule Culture in Reciprocal Hybridization between <i>B. campestris</i> L. and <i>B. oleracea</i> L.

Abstract

Abstract Ovule culture was used to overcome postzygotic interspecific incompatibility in reciprocal crosses between Brassica campestris and B. oleracea. Hybrid plants were obtained from 82 % of all reciprocal pollinations, representing 91 % of the attempted combinations. Comparisons of the embryo culture and the ovule culture indicated a significantly higher germination rate after ovule culture.
