The photosynthetic pigments content in the cotyledon leaves of 2 green samples of oil flax and their mutants with different types of chorophyll deficiency was studied at the germination stage. It was found that both green samples of flax differed in the content of chlorophylls a, b and carotenoids. In mutants with chlorophyll deficiency of different types, the content and ratio of the main photosynthetic pigments (chlorophylls a, b) are determined by the type of mutation and do not depend on the year conditions. The xantha mutant showed a significant increase in chlorophyll a content and a decrease in chlorophyll b compared to the initial variety. The mutant xantha-viridis differs from the green sample by a significant decrease in the chlorophyll b content. The least differences from the control green plants were observed in mutants with chlorophyll deficiency of the viridis type.
