The study of natural gene pool of plant resource species, promising for selection

On the example of representatives of genus complexes Rhaponticum, Trollius and Rosa which are at the same time both resource, and rare use of classical and modern techniques on collecting in the nature, studying and identification of material and allocation of forms, perspective for selection were shown. Collecting plant material of such objects in natural habitats is carried out after a preliminary estimate of a state cenopopulation (central processing unit) of resource types. The following characteristics are for this purpose used: ecological and effective density, population type on classification "delta omega", a restoration index, a percentage indicator of generative individuals. On the basis of obtained data the conclusion about the possibility of withdrawal for a bioresource collection of material was made of a cenopopulation in the form of seeds or live plants. For the further creation of heterozygous introduction populations, ISSR analysis of samples from different cenopopulations was carried out in order to determine the coefficient of genetic similarity...
