The induced haploidy through in vitro gynogenesis in sugar beet is effective method for the selection of valuable gene recombinations determining the expression of efficient traits of that crop. Ten years test results for the resistance to powdery mildew and Cercospora leaf spot of stabilized multigerm dihaploid sugar beet lines and their hybrid combinations are being reported. The performance of the tested material proves, that the multigerm dihaploid pollinators are differentiated recombinant lines with favorable combinations of genetic material, including genes responsible for the high resistance to the agents of powdery mildew and Cercospora leaf spot fungal diseases. The higher resistance of the dihaploid multigerm pollinators dominates in their diploid hybrid combinations. The heritage factors for higher resistance to both diseases of the maternal component dominate in the tested triploid hybrids. There are good prospects of using these pollinators in the hybrid breeding schemes.
