Abstract
Wild ancestors and close relatives provide valuable genetic resources for improving cultivated carrots (Daucus carota L. subsp. Sativus (Hoffm.) Arcang.). Remaining knowledge gaps in taxonomy, distribution and characteristics of commercially valuable traits limit their wide usage in selection and negatively affect ex situ (gene bank) and in situ (natural habitat) conservation planning. Since some populations of wild plants are adapted to extreme climatic conditions, unfavorable soils, pests and diseases, they have significant potential to contribute to selection to solve emerging and foreseeable future problems in the agrotechnology of table carrots. The aim of the study is to study wild species of Daucus genus by morphological characteristics in the Moscow region in order to expand their usage in selection and ex situ preservation. According to the research results, it was found that the trait “anthocyanin colour of the leaf petiole” of D. setifolius (Turkey, Antalya) is a marker when hybridizing with cultivated carrots. The marker trait “anthocyanin colour of flowers” was recorded in D. carota L. var. maximus, D. carota (Tajikistan), D. carota (Uzbekistan, Kashkadarya region). D. carota subsp. halophilus is a genetic source for resistance to salt stress. In the future, the formation of Daucus germ plasm collections and ex situ preservation contribute to the expanded usage of wild species in selection for resistance of cultivated table carrots to bio- and abiostress.
