[Molecular-genetic identification and certification of soybean (Glycine max L.) cultivars].

An approach to certification of soybean genotypes has been developed. The procedure employs three methods of DNA analysis based on polymerase chain reaction (PCR): PCR with arbitrary primers (AP PCR), simple sequence repeat polymorphism (SSRP) analysis, and inter-simple sequence repeat (ISSR) analysis. The approach to certification proposed may be used in both genetic and breeding research and seed production.

[Distribution of alleles of the WMS261 locus, marking the gene for the dwarf gene Rht8, in common wheat cultivars in southern Ukraine].

The use of codominant microsatellite molecular markers allows one to study the inheritance and distribution of alleles linked to important agronomic characters. A microsatellite locus WMS261 tightly linked to a dwarfing gene Rht8 was analyzed in wheat cultivars and selection material of the Institute of Plant Breeding and Genetics. PCR screening of common wheat cultivars produced in the southern Ukraine showed the prevalence of a 192-bp allele at locus WMS261 that indicates adaptive significance of a corresponding allele of the Rht8 gene in the southern regions.
