| Description
| - V roce 1922 popsal F.A.Novák vznik křížence mezi druhy Tragopogon porrifolius a T. pratensis (T. ×mirabilis) v zahradě zemědělské školy v Roudnici nad Labem. Přestože byly tento hybrid i lokalita zmíněny ve všech důležitých určovacích příručkách, nikdo další tento případ hybridizace nestudoval. V současné době se na místě bývalé zahrady nachází objekt podniku Ross (dříve Roudnické strojírny). V jeho areálu stejně jako v areálu železniční stanice Roudnice-Hracholusky a v přilehlých ulicích roste velká populace hybridních kozích brad. Ty se liší celým souborem znaků od svých rodičů, v některých případech jsou i mimo rozsah variability obou rodičů. Celkově je variabilita této populace velmi vysoká, a to nejen v morfologických znacích, ale např. i ve formě vzrůstu rostlin, kde se vyskytují jak vysoké (až 1,5 m) rostliny, tak i nízké rostliny s vystoupavými stonky. Za nejzajímavější skutečnost považujeme to, že ač oba rodiče jsou krátkověké trvalky kvetoucí jednou za život, tak hybridní ... (cs)
- The population of hybrid origin between Tragopogon porrifolius and T. pratensis (T. ×mirabilis), which occurs in SW part of the town of Roudnice na Labem, N part of Central Bohemia, was analysed with respect to its morphology, fertility, life history, ploidy level and DNA content. Both parental species show relatively narrow morphological variation; they are biennials (monocarpic perennials), diploids. T. pratensis is a native species in the Czech Republic, T. porrifolius was cultivated there in the past. The plants of the hybrid population are extremely morphologically variable, with variation ranges of some characters overlapping that of parental species (e.g., ligules are often longer than involucral bracts, peduncles are often lanate). Only diploids were found within the hybrid population; however, they have substantially lower DNA content than both parents (18% lower than T. pratensis, 42% lower than T. porrifolius). The plants of the Roudnice hybrid population are polycarpic p...
