Avena sativa, Blumeria graminis, molecular markers, resistance


The selection of specific plants with desirable traits supported by molecular markers is one of the most important tools in modern breeding programs, which lead to reduce time and cost of selection. The aim of presented study was identification of dominant markers associated with Pm4 powdery mildew resistant gene in oat. To identify dominant silicoDArT markers for Pm4 gene, F2 mapping population ‘Av1860’ × ‘Fuchs’ were analyzed using DArTseq methodology. Among obtained 46 230 silicoDArT markers, 126 markers were high correlated with resistance to powdery mildew in oat conditioned by Pm4 gene. Among selected markers, 48 sequences have been chosen for potential conversion into specific STS markers. Finally, only 20 were suitable for primer design. As a result, 5 converted markers amplified expected products in resistant bulks, 3 of them segregated according to resistance in the whole population and shoved high correlation coefficient between marker and phenotype observation. Converted markers based on PCR could be used for identification of Pm4 gene in oat. Obtained results confirm the possibility of converting silicoDArT markers into PCR-based technique, which can be used in marker assisted selection (MAS).
