Abstract
Identifying among varieties and natural forms of roses were carried out using ISSR thechnics to determine kinship. It was studied 6 foreign varieties, 16 varieties bred in Nikitsky Botanical Garden, as well as 2 natural forms (Rosa canina and Rosa chinensis). Despite some samples breaking into three clades, many of them don’t belong to any of these groups due to the lack of relative ties, that confirms the high genetic diversity in the studied material. The revealed molecular genetic differences in rose forms and varieties can be used to identify and certify cultivars promising for their complex resistance to the continental climate conditions.
Highlights
Roses, or rather various species and hybrids of representatives of the genus Rosa L., are the leading culture in the world decorative gardening
ISSR markers are used in genetics, phylogenetics, and breeding to study genetic diversity and differentiation of genotypes [13]
The work objective is to determine the relationship between two natural forms and 22 varieties of foreign and Nikitsky Botanical Garden (NBG) breeding from the CSBG SB RAS’ collection
Summary
Rather various species and hybrids of representatives of the genus Rosa L., are the leading culture in the world decorative gardening. The Central Siberian Botanical Garden of SB RAS (CSBG SB RAS) has been long studying the complex resistance to the continental climate conditions among different rose varieties of Nikitsky Botanical Garden (NBG) selection. It carries out biomorphological studies of formation shoot systems (FSS), as well as a histochemical research of the seasonal dynamics of starch, sugars, proteins, lipids and shoot lignification processes. Since representatives of the complex of the genus Rosa L. are part of the CSBG collection of biological resources, the evaluation of rose varieties using the molecular genetic method has begun. The work objective is to determine the relationship between two natural forms and 22 varieties of foreign and NBG breeding from the CSBG SB RAS’ collection
