As a result of studies of colchicine-treated proembryogenic cell suspensions and globular somatic embryoids of the hybrid form E-342 in liquid-medium variants, a universal methodology for the development of globular, heart-shaped, and torpedo-shaped embryoids for various grape genotypes is developed. Using the VMC7f2 and p3_VvAGL11 marker-assisted selection (MAS) markers associated with seedlessness, we detect hybrids with alleles linked to the seedless trait in the population of hybrid seedlings.
