Impacts of genetically modified (GM) crops on biodiversity are examined by the Cartagena Protocol Domestic law in Japan. When a GM crop is shown to have no adverse effects on biodiversity, its cultivation and commodity usage are approved. Brassica napus can cross their relatives, B. juncea and B. rapa that grow in the reversides, roadsides and vacant lots. However, there are no summaries available for the biology of the wild brassica species in Japan unlike other crops that have been characterized in documents published by OECD. In this report, we excerpted and compiled essential botanical information about B. juncea, B. rapa and B. napus from the scientific literature. This compilation includes information about the classification, distribution, life history, growth characteristics, reproductive biology, hybrid offspring characteristics and introgression.
