Detailed explanation-1: -Raphanobrassica is an allopolyploidal product produced as a result of an artificial genetic hybridization cross between radish (Raphanus) and cabbage (Brassica). The first filial generation product formed was a sterile diploid which on tetraploidization produced a fertile amphiploid.

Detailed explanation-2: -Raphanobrassica. Artificial hybridization of radish (Raphanus) and cabbage (Brassica) (both 2N = 18) produces a sterile first-generation hybrid with one diploid chromosome set from either parent. Tetraploidization eventually produces a stable, true-breeding hybrid (Raphanobrassica).

Detailed explanation-3: -Brassicoraphanus or Raphanobrassica is the name for all the intergeneric hybrids between the genera Brassica (cabbages, etc.) and Raphanus (radish). The name comes from the combination of the genus names.
