Nine rye genotypes and pollen mixture of three maize cultivars were evaluated for embryo formation in rye x maize crosses. Based on cleared ovule preparations, the development of embryo and endosperm were observed at 48, 72 and 96 h after pollination. Embryos were formed in eight cross combinations (3.3% to 23.3% depending on rye genotype), but in five combinations ovules had both embryos and endosperm nuclei. In a sample of 344 cleared ovules, 28 (8.1%) had both embryo and endosperm, 15 (4.4%) had only embryo, and 13 (3.8%) had only endosperm.
