Abstract

Chrysanthemum is one of the most important and popular ornamentals over the world. Breeding of new pedigrees depends mainly on conventional crossing. Chrysanthemum genetic resources were categorized into three groups. Here we introduce the wild species and related genera of Chrysanthemum in order to extend the genetic resources that can be used for genetic improvement of chrysanthemums by hybridization. In the genus Chrysanthemum and closely related genera, there are many wild species that are able to cross successfully with modern chrysanthemums. These represent important genetic resources for introducing new characters into florist's chrysanthemums. The genus Chrysanthemum consists of more than 40 species distributed mainly in East Asia. More than 20 species of Chrysanthemum are native to China. Unfortunately, little of this information has been published in western languages. In this paper, we also provide an overall review of the basic information of the wild species of we have collected in China in order to understand and exploit those genetic resources much better. We have collected about 17 wild species and studied their useful characters in the past several years. These species include C. oreastrum (Hance) Y. Ling, C. hypargyrum (Diels) Y. Ling et C. Shih, C. zawadskii (Herbert) Tzvelev, C. chanetii (H. Léveillé) C. Shih, C. naktongense (Nakai) Tzvelev, C. mongolicum (Y. Ling) Tzvelev, C. argyrophyllum (Y. Ling) Y. Ling et C. Shih, C. rhombifolium (Hemsley) Y. Ling, C. vestitum (Hemsley) Y. Ling, C. dichrum C. Shih, C. glabriusculum (W. W. Smith) C. Shih, C. indicum (Linnaeus) Des Moulin, C. lavandulifolium (Fischer ex Trautvetter) Kitamura, C. foliaceum G. F. Peng, Shih et S. Q. Zhang, C. nankingense (Handel-Mazzetti) X. D. Cui, C. potentilloides (Handel-Mazzetti) C. Shih and C. maximowiczii (Komarov) Tzvelev. In addition to this genus, we have collected some species of the related genera including Brachanthemum mongolicum Krascheninnikov, B. pulvinatum (Handel-Mazzetti) C. Shih, B. gobicum Krasch, Ajania fastigiata (C. Winkler) Poljakov, A. achilleoides (Turczaninow) Poljakov ex Grubov, A. khartensis (Dunn) C. Shih, A. fruticulosa (Ledebour) Poljakov, A. pallasiana (Fischer ex Besser) Poljakov, Phaeostigma salicifolia (Mattf.) Muld., Elachanthemum intricatum (Franchet)Y. Ling et Y. R. Ling and two endemic species of Opisthopappus including O. taihangensis (Ling) Shih and O. longilobus Shih in China.
