Merr.) required absence or low sensitivity to photoperiod for adaptation to high latitudes. There are multiple loci known as E series or eleven major genes E1 – E11 and J gene, which generally controlled time to flowering and maturity, two traits that are highly influenced by photoperiod [1, 2]. Among these loci dysfunctional alleles of maturity genes E3 and E4, which are phytochrome A genes, are involved in soybean photoperiodic insensitivity. For most genotypes of soybean varieties and lines created in different breeding centers of Ukraine, identification of alleles by allele-specific markers for loci E3, E4 was not performed. Due to the contradictions and ambiguity of the results of our previous analysis with microsatellite markers associated with loci E3, E4 [3], we decided to focus on the analysis of alleles of these genes, using allele-specific markers.enE genesPCR-diagnosticsPerspective linesSoybean varietiesArticle
