Nejstarší popis kosatců vpřírodě pochází z básnické sbírky Shugyobushu, kterou napsal Jien (žil v letech 1155 – 1225). První známé záznamy o pěstování japonských kosatců pocházejí z knihy Sujyaku Ourai, kterou napsal Kameyoshi Ichiso (1408-1481). Popisuje již také barevné odchylky, které je možné najít v přírodě. V roce 1681 je v knize Kadan-Komoku popis několika odrůd a z roku 1799 pochází zmínka o stovkách pěstovaných odrůd. První japonské kosatce dovezl do USA Thomas Hogg v roce 1869, první rozsáhlejší komerční dovoz proběhl v roce 1877. Tetraploidní japonské kosatce nejsou známy z přírody a byly získány poprvé v 60. letech pomocí kolchicinu. První ´Raspberry Rimmed´vyšlechtil Currier McEwen v roce 1979 popsaný jako jednoduchý tetraploid, bílý s malinov ěčervenými okraji a žíháním. Ve šlechtění polyploidních japonských kosatců pokračoval Němec Eckard Berlin a Japonci Mototeru Kamo, Hioshi Shimizu, Teutonu Yabuya. Tetraploidní japonské kosatce mají širší, tmavěji zelené listy a větší pevnější květy.

Kombinují barvy japonských kosatc ů (modrá, fialová, růžová) se žlutým zbarvením I. pseudacorus, obvykle mají výrazné hnědé či fialové oko a žilkování zděděné od kosatce žlutého. Listy jsou širší a trsy volně jší než u japonského kosatce, květy se obvykle otvírají v úrovni či níže než listy, nikoliv nad listy jak je tomu u japonských kosatců. Stonky jsou větvené, nesou 10 – 16 poupat a kvetou i 3 týdny. Hybridy jsou sterilní. Možnost křížení těchto dvou druhů byla známa již dříve, ale hybridy se rozšířily až díky práci Japonce Hiroshi Shimizu koncem 20. století. Nejstarší je kultivar Kinshikou (Hiroshi Shimizu by Carol Warner, R. 2004) Hybridy vodních a japonských kosatců KosatceKosatce lousiánské lousiánské Iris hexagona Iris fulva Iris nelsonii • Centrum šlechtění těchto kosatců bylo v americkém New Orleans. • Začátkem 20. století sestry Mary Nelson a Ethel Hutson vytvořily sbírku planých kosatců série Hexagonae. S jejich pěstováním a prvními pokusy se šlecht ěním započal Ellsworth Woodward profesor umění na Newcomb College také v New Orleans, který je používal jako modely v malířství. • Nejstarší oficiální hybridy vznikly ve Velké Británii. Nejuznávanější světový odborník na kosatce a autor monografie ‘Genus Iris’ W. R. Dykes kolem roku 1910 zkřížil Iris fulva x I. brevicaulis a představil v roce 1911dvě odrůdy – ´Fulvala´ a ´Fulvala Violacea´. • Pěstování lousiánských kosatců se věnuje v jižních státech USA mnoho nadšenců, které se v roce 1941 sdružují pod vedením profesora zahradnictví Ira S. Nelsona do Mary Swords De Balon Iris Society. • První výstavu lousianských kosatců pro veřejnost společnost uspořádala v roce 1943. • Pokrok ve šlechtění nastal po popisu a introdukci Iris nelsoni ve 40. letech. Tento druh se snadněji křížil a dal základ většině dnes pěstovaných odrůd. • [ ´Black Gamecock´ Kosatce lousiánské hybridy Brunsfire Moon Handmaiden Profesor Paul Cajun Love Red Velvet Tripetalae Iris tridentata Iris setosa Iris hookeri Kosatce hřebínkaté – Iris lacustris Iris prismatica Iris longipetala Iris missouriensis Kosatce sibiřské Plané sibiřské kosatce Iris sanguinea Iris sibirica Iris wilsonii Iris chrysographes Iris forestii • Zahradní odrůdy pocházejí především ze dvou druhů – kosatce sibiřského a Iris sanguinea. Oba druhy mají 2n = 28, snadno se spolu kříží. Většina zbývajících druh ů má 2n = 40, s Iris sibirica je není možné kř ížit • Pěstování sibiřských kosatců je známé od začátku 17. století v Anglii a do stejného období spadá introdukce Iris sanguinea do zahrad v Japonsku. • Zahradní odrůdy sibiřských kosatců jsou známé již začátkem 19. století – bělokvětý Iris sibirica ´Alba´ byl popsán v roce 1809, zakrslý Iris sibirica ´Acuta´ v roce 1830 a plnokvětý I. sibirica ´Flore Pleno´ v roce 1852. • Do roku 1900 bylo vyšlechtěno pouze 11 odrůd. Zvrat znamenala introdukce Iris sanguinea , který dovezl Peter Barr v roce 1900 do Anglie. • V roce 1957 vyšlechtil Frederick W. Cassebeer odrůdu ´White Swirl´ s velkým plochým bílým květem, která byla později často používána ve šlecht ění pro charakteristický tvar květu. • První tetraploidní sibiřské kosatce vznikaly kolem roku 1965, ale jednalo se o nestálé chiméry. První stálé tetraploidní sibiřské kosatce získané pomocí kolchicinu - ´Orville Fay´ a ´Fourfold White´ registroval Currier Mc Ewen v roce 1970. V roce 1975 bylo již registrováno 590 odrůd sibiřských kosatc ů.

Byly pěstovány ve Francii ve školkách M. Lemmonniera. Na konci století sir Michael Foster dováží první rostliny do Anglie a šlechtí první hybridy. Nejznámější je ´Monspur´ (Foster, 1890), který vznikl zk řížením Iris monnieri a I. spuria. • Ve 20. letech 20. století Američan T. A. Washington začíná s cíleným šlechtěním kosatců této skupiny. Za základ bere již jmenovanou odrůdu a další taxony jako I. spuria halophila. Získává rostliny s celou barevnou škálou od bílé, žluté po tmavě modrou. Později jsou tyto kosatce dále šlechtěny vEvropě a na Novém Zélandě. • Odrůdy se dělí podle dormance – teplomilné, pěstované v Kalifornii, na JV USA či teplých oblastech Evropy, které mají období klidu po odkvětu v létě.

Gryshko National Botanical Garden, National Academy of Sciences of Ukraine, Timiryazevska str. 1, 01014 Kyiv, Ukraine; [email protected] Received: 27.01.2020 | Accepted: 23.05.2020 | Published: 30.06.2020 Abstract The objective of this study was to analyze the morphological structure and to reveal common and distinguishing features of the fruit in rare steppe species Iris halophila, I. pumila and I. hungarica introduced in conditions of meadow-steppe cultural phytocenosis in the M.M. Gryshko National Botanical Garden, National Academy of Sciences of Ukraine (NBG). Material and methods. Fruits of I. halophila, I. pumila and I. hungarica were collected on the botanical- geographical plot “Steppes of Ukraine” of NBG during 2015–2019. Fruit parameters were measured using a regular ruler. Morphological terms are provided, according to Artyushenko & Fedorov (1986). Colors were determined by Bondartsev’s (1954) scale. Results. In all analyzed species, the fruit is a trimeric and trilocular loculicidal capsule with multi-seeded locules. This capsule is erect, straight, leathery, glabrous, opening by dehiscence from top to bottom along the dorsal veins of carpels. The morphological peculiarities of the fruits, which may be additional diagnostic characters of these species, are established. In particular, in I. halophila capsule is cylindrical, with the upper part elongated into the apical spout (long, thin, bent to the side).

    Hybrid Fitness, Adaptation and Evolutionary Diversification: Lessons

    Heredity (2012) 108, 159–166 & 2012 Macmillan Publishers Limited All rights reserved 0018-067X/12 www.nature.com/hdy REVIEW Hybrid fitness, adaptation and evolutionary diversification: lessons learned from Louisiana Irises ML Arnold, ES Ballerini and AN Brothers Estimates of hybrid fitness have been used as either a platform for testing the potential role of natural hybridization in the evolution of species and species complexes or, alternatively, as a rationale for dismissing hybridization events as being of any evolutionary significance. From the time of Darwin’s publication of The Origin, through the neo-Darwinian synthesis, to the present day, the observation of variability in hybrid fitness has remained a challenge for some models of speciation. Yet, Darwin and others have reported the elevated fitness of hybrid genotypes under certain environmental conditions. In modern scientific terminology, this observation reflects the fact that hybrid genotypes can demonstrate genotypeÂenvironment interactions. In the current review, we illustrate the development of one plant species complex, namely the Louisiana Irises, into a ‘model system’ for investigating hybrid fitness and the role of genetic exchange in adaptive evolution and diversification. In particular, we will argue that a multitude of approaches, involving both experimental and natural environments, and incorporating both manipulative analyses and surveys of natural populations, are necessary to adequately test for the evolutionary significance of introgressive hybridization. An appreciation of the variability of hybrid fitness leads to the conclusion that certain genetic signatures reflect adaptive evolution. Furthermore, tests of the frequency of allopatric versus sympatric/parapatric divergence (that is, divergence with ongoing gene flow) support hybrid genotypes as a mechanism of evolutionary diversification in numerous species complexes.

For more information, please contact [email protected]. lntrogression and Its Consequences in Plants Abstract The or le of introgression in plant evolution has been the subject of considerable discussion since the publication of Anderson's influential monograph, Introgressive Hybridization (Anderson, 1949). Anderson promoted the view, since widely held by botanists, that interspecific transfer of genes is a potent evolutionary force. He suggested that "the raw material for evolution brought about by introgression must greatly exceed the new genes produced directly by mutation" ( 1949, p. 102) and reasoned, as have many subsequent authors, that the resulting increases in genetic diversity and number of genetic combinations promote the development or acquisition of novel adaptations (Anderson, 1949, 1953; Stebbins, 1959; Rattenbury, 1962; Lewontin and Birch, 1966; Raven, 1976; Grant, 1981 ). In contrast to this "adaptationist" perspective, others have accorded little ve olutionary significance to introgression, suggesting instead that it should be considered a primarily local phenomenon with only transient effects, a kind of"evolutionary noise" (Barber and Jackson, 1957; Randolph et al., 1967; Wagner, 1969, 1970; Hardin, 1975).

    Newsletter No:12 Contents:- Editorial Obituaries Contributions:- Notes on Lilies Margaret and Henry Taylor Some Iris Species David Ledsham 2nd Czech International Rock Garden Conference Kay McDowell Homage to Catalonia Liam McCaughey Alpine Cuttings - or News Items Show News:- Information:- Web and 'Plant of the Month' Programme 2013 -2014 Editorial After a long cold spring I hope that all our members have been enjoying the beautiful summer, our hottest July for over 100 years. In the garden, flowers, butterflies and bees are revelling in the sunshine and the house martins, nesting in our eaves, are giving flying displays that surpass those of the Red Arrows. There is an emphasis ( almost a fashion) in horticultural circles at the moment on wild life gardening and wild flower meadows. I have always felt that alpines are the wild flowers of the mountains, whether growing in alpine meadows or nestling in among the rocks. Our Society aims to give an appreciation and thus the protection and conservation of wild flowers and plants all over the world. Perhaps you have just picked up this Newsletter and are new to the Society but whether you have a window pot or a few acres you would be very welcome to join the group and find out how much pleasure, in many different ways, these mountain wild flowers can bring. My thanks to our contributors this year who illustrate how varied our interest in plants can be. Not only did the Taylors give us a wonderful lecture and hands-on demonstration last November but kindly followed it up with an article for the Newsletter, and I hope that many of you, like me, have two healthy little pots of lily seedlings thanks to their generous gift of seeds.
