The 2C nuclear DNA content has been estimated by flow cytometry in 18 species and botanical forms of the genus Lupinus (family Fabaceae), using propidium iodide as a fluorescent dye. They represented distinct infra-generic taxonomic groups and differed in somatic chromosome numbers. Estimated 2C DNA values ranged from 0.97 pg in L. princei to 2.44 pg in L. luteus, which gives a more than 2.5-fold variation. Statistical analysis of the data obtained resulted in a grouping that supports the generally accepted taxonomic classification of the Old World lupins. The rough-seeded L. princei turned out to be an interesting exception, getting closer to smooth-seeded species. Results of DNA content analyses are discussed with regards to the phylogenetic relationships among the Old World lupins and some aspects of the evolution of the genus. © 2003 Annals of Botany Company.
