Anther culture in the breeding process of winter wheat. III. Ability of winter wheat F 1 populations with the two heterozygous 1AL–IAS/1AL–IRS and 1BL–1BS/1BL–IRS chromosome pairs Application of anther culture to four F 1 hybrids between the IBL–IRS (‘Amigo’) and several 1BL–IRS wheat‐rye translocation forms yielded 129 green pollen plants in an average embryo induction frequency of 17.6 %. A total of 2632 anthers was inoculated. 25 % and 42 % of the regenerated plants were haploid and spontaneously doubled haploid, and 33 % had abnormal chromosomal structure. After chromosome doubling treatment 87% of all pollen plants set seeds. By means of multiple peroxidases and Giemsa C‐banding patterns, the anther culture progeny could be further classified into 16 plants without the short arm of IR‐chromosome of rye, 21 IAL–IRS and 50 1BL–IRS translocation lines and into 16 IAL–IRS, IBL–IRS double translocation lines according to the four possible characteristic types of F 2 gametes of the tested F 1 hybrids. Advantages of the haploid technique for the selection of desirable traits and the meaning of the IRS genes in wheat are discussed.
