Summary

A research has been carried out on the occurrence of 2n gametes in Brassica oleracea and on their possible way of origination. After microsporogenesis it appeared that unreduced PMC's, dyads and triads occurred. Giant pollen grains with two (diploid) and four (haploid) generative nuclei, respectively, were found, resulting from a deviating cytokinesis and karyokinesis. Diploid heterozygous matromorphic embryos may develop from such unreduced gametes formed after macrosporogenesis.
