Abstract
The application of the classical selection of diatoms on the example of the genus Haslea is
considered. The ability of some representatives of this genus to synthesize marennine and
marennine-like pigments is interesting to researchers and owners of oyster farms because these
unique pigments can colorise the tissues of mollusks in a greenish color and improve their
organoleptic properties. It has been shown that marennine has antibacterial, antiviral,
antioxidant and other biological activities. It is assumed that the efficiency of marennine
biosynthesis can be increased by obtaining highly productive strains by selection, which was
not previously carried out in diatoms. The assessment of the possibility and prospects of
applying the methods of classical breeding in relation to representatives of the genus Haslea is
given. It is shown that significant success has been achieved to date in the study of the life
cycle, crossing systems and other features of the reproductive biology of representatives of the
genus Haslea, which allows them to carry out classical selection by selection, hybridization
and obtaining descendants of the next generation.
