In this research was conducted to compare three methods of haploid production in hexaploid wheat through chromosome elimination (wheat ×maize cross) for use in the breeding programs. The three methods were A) classical B) detached and C) intermediate or sime-detached. Parental materials were 11 wheat F1 genotypes as female parents and BS572 hybrid as male parent. The traits studied were percentage of seed set, percentage embryo formation and percentage of haploid plantlet production. Among all the three methods, the intermediate C) method was significantly superior to others in which the seed set, embryo formation and haploid plant production were 84.98%, 21.73% and 49.52% respectively. Overall, haploid production from the initial number of pollinated florets was 13.80% in this method Among all the three methods, the intermediate C) method was significantly superior to others in which the seed set, embryo formation and haploid plant production were 84.98%, 21.73% and 49.52% respectively. Overall, haploid production from the initial number of pollinated florets was 13.80% in this method..
