Abstract: Frequencies of embryo formation in crosses of wheat (Triticum aestivum, 2n = 6x= 42) with Hordeum bulbosum (2n = 4x = 28), Zea mays (2n = 2x = 20) and Tripsacum dactyloides (2n = 4x = 72) were compared. The results showed that Tripsacum dactyloides was the same elatively insentive to the action of dominant alleles at the Kr loci as maize. Frequency of embryo formation was higher when crossed with Tripsacum dactyloides than that of maize as male parent. In addition, Tripsacurn dactyloides also were able to offer pollen conveniently as the same as Hordeum bulbosum did. Therefore, It is suggested that Tripsacum dectyloides has great potentiality as a pollen donor in wheat intergeneric corsses.

Key words: Wheat, Tripsacum dectyloides, Intergeneric cross
