| Abstract : This research was carried out to study the spontaneous chromosome doubling of two wheat genotypes (W23 and W86) by using androgenesis technique. For this purpose a completely randomized design with 3 replications under in vitro condition was used. Statistical analysis of embryogenesis and cytogenetic results showed that genotype had a significant effect on haploid embryogenesis (P<0.01) and spontaneous chromosome doubling (P<0.05). The results showed that the genotype W23 had higher potential to show haploid embryos (76 embryos from 100 anthers) whereas the genotypes W86 had the lowest and gave 22 embryos from 100 anthers. Regarding spontaneous chromosome doubling, the highest percentage (19%) was observed in the genotype that had the lowest embryogenesis (W86) and the lowest (16%) was observed in the genotype with the highest embryogenesis (W23). All large embryos which used had high regeneration ability and good performance in plantlet formation. Key words: Triticum aestivum L., haploid embryogenesis, spontaneous chromosome doubling, androgenesis | ||
