摘要：

Intergeneric hybrids between Moricandia arvensis (a C3-C4 intermediate species) and Brassica oleracea (a C3 species) were obtained through ovary culture. Many hybrid embryos (2.71 per pollination) were produced in the M. arvensis × B. oleracea cross, but none were produced from the reciprocal cross. Though most embryos failed to develop into plantlets directly, plants were obtained by inducing shoots from hypocotyl explants. The hybrid plants were morphologically intermediate between the parents except for the petal color. Cytogenetic observations indicated that partial homology existed between the two genomes. Ovary culture is an efficient technique for gene transfer from M. arvensis to B. oleracea. © 1990 Kluwer Academic Publishers.
