Differentiation of the progeny of smut spores of Ustilago zeae (Beckm.) Ung. in relation to the ploidy of the parasitic phase and type of nutrition of compatible haploids



Differentiation of the progeny of smut spores of Ustilago zeae (Beckm.) Ung. in relation to the ploidy of the parasitic phase and type of nutrition of compatible haploids



Mikologiya i Fitopatologiya 19(4): 329-333



A diploid str. of U. zeae obtained by crossing compatible auxotrophic haploids on a nutrient medium was stable. Spontaneous haploidization and splitting in culture was not observed in 3 yr and during meiosis during germination of smut spores. Formation of b-gene homozygotic diploids in the spore progeny might be the result of mitotic recombination during its development in the maize host.
