Popis: In Brasslca cultlvars Includlng six species of different grenome constitution, Brassica campestris (AA), B.nigra (BB), B.oleracea (CC), B.juncea (AABB), B, napus (AACC) and B, carinata (BBCC), flavonoid patterns were analysed paper chromatographically in refcrence to their genome constitution. The comparison was made with seven pigment spots involving two anthocyanins and five yellow flavonoids. As a consequence, chromatographic patterns of the above five species except B. campestris were distinguished from each other by their flavonoid components. Alrlong the cultivars of B. calmpestris, the ffavonoid patterns differ considerably from each other, suggresting that this species may involve a number of diverse subspecies as regards the flavonoid composition. Moreover, it was shown that in amphidiploid species the flavonoid components come out together as a sum of flavonoids appearingf :in both diploid ancestors. In the course of chemicogenetic studies on ffavonoids in Brassica and Raphanus, atternpt was made to examine the nature and distribution of flavonoid pigments in related species of the genus Brassica. According to the previous survey, some of the flavonoid components seemed to be common to the majority of the species in this genus. The present work was carried out to see whether some corlelation exists between genome and fiavonoid pattern in the genus Brassica. As a consequence, it has proved that the correlation does exist, from which certain degree of speciation may be presumed armong various cultivars in thig genus.
