Diagram showing NOR landmarks based on globally published reports in the three species of the genus Allium occurring in India. The modal karyotypes for subgenera are adopted and modified after Peruzzi et al. (2017). Diagrams showing NORs are modified after the published reports on A. ampeloprasum (as A. porrum in Maragheh et al. 2019), A. sativum (Bacelar et al. 2021) and A. cepa (Fajkus et al. 2016).
