[Distribution of alleles of the WMS261 locus, marking the gene for the dwarf gene Rht8, in common wheat cultivars in southern Ukraine]. / Rasprostranenie allelei lokusa WMS261, markiruiushchego gen korotkostebel'nosti Rht8, u sortov miagkoi pshenitsy iuzhnoi Ukrainy.

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.
