Allohexaploids in the GenusBrassica

Allohexaploid Brassica hybrids (2n = AABBCC) have been the subject of plant breeding and research for many years, both to increase our understanding of polyploid plant evolution and to benefit plant breeding. This review summarizes and evaluates the different approaches to producing these hybrids using the six interrelated crop species (three diploids and three allotetraploids) of the famous “U’s Triangle” as starting material.
