Intergeneric F 1 hybrids between Raphanus sativus (2n = 18, RR) and Moricandia arvensis (2n = 28, MaMa) have been produced through ovary culture followed by embryo culture, when M. arvensis was used as a pistillate parent. Six BC 1 plants were also obtained through ovary culture followed by embryo culture in the backcross of an amphidiploid F 1 , hybrid with R. sativus cv. ‘Pink ball’. Two BC 1 plants were ses‐quidiploids (2n = 32, MaRR), and the other BC 1 , plants were hyperploid with 2n = 55, having MaMaRRR genomes. BC 2 , seeds were obtained by conventional pollination in the successive backcross of two sesquidiploid BC 1 , plants with R. sativus cv. ‘Pink ball’. Their seed set percentages were 12.7% and 17.0%, respectively. These novel hybrid plants and derived progenies may be valuable materials for the genetic investigation and breeding of Brassiceae , including R. sativus.
