After the test populations, we have selected the best samples with high yield and with high content of polyunsaturated greasy acids in oil seeds. These samples are interesting as a valuable source material for breeding. We have chosen and described the signs of advanced samples of different geographical origin. The selected signs will be used to develop testing procedures for distinctiveness Oenothera biennis L., as well as for create a table of signs for test on distinctiveness.
