Production of haploid plants followed by chromosome doubling can shorten the duration of plant breeding programs. Barley haploid plants can be obtained by interspecific crossing between barley (Hordeum vulgare L.) and Hordeum bulbosum L. This paper describes the haploid breeding method applied for malting barley. There were varietal differences in embryo formation and haploid production among the barley genotypes. The varietal differences in embryo formation were due to the difference in the pollen tube growth and the rate of chromosome elimination 3 to 5 days after pollination. To improve the efficiency of haploid production, superior clones of H. bulbosum were selected. Haploid production method using intergeneric crossing was newly developed. F1 plants derived from two cross-combinations of barley cultivars were crossed with H. bulbosum. As a result, 209 doubled haploid plants were obtained and 4 elite lines of malting barley were selected. These lines were superior to the check cultivar in agronomic performance and malting quality.
