Abstract: Observations were made on the fertilization and early embryo development in intergeneric cross between Avena magna and Avena nuda. The pollen germination of Avena nada appeared to be normal on the stigma of Avena magna and the pollen tubes grew into the style and entered the embryo sacs. In 168 florets fixed after pollination, 2.38% had double fertilization and produced embryo and endosperm, but the endosperm development was slower than that of the embryo, 1.79% had only embryo and 1.19% had only endosperm. The frequency of fertilization and embryo formation were 5.36% and 4.17% respectively. Due to the lack of endosperm or its abnormal development and abortion, no viable seeds were poduced. Cytoembryological evidence was provided for crosses between Avena magna and Avena nuda.
