Our previous research established that viral infection alone or in combination with gamma radiation generate useful phenotypic variation of some quantitative traits and can be used to enhance genetic variability in barley regenerants (R0) [2]. According to data from the litera-ture phenotypic variation of plant traits can be result of genetic and epigenetic changes under different biotic and abiotic stress factors including gamma rays and viruses [1, 3, 5]. One of major epigenetic modification is DNA methylation that modifies gene expression and is easier passed through generations. In the same time, it is important to highlight that epigenetic modi-fications show instability and are influenced by the environment, and some epigenetic changes may result in heritable phenotypic variation whereas others are not [1, 5]. In the context of the above, it is purpose to evaluate effect of barley stripe mosaic virus (BSMV) and gamma rays on agronomic trait in barley offspring (R1) compared to the regenerants R0. |
