    regeneration and haploid production were strongly influenced by genotypes, embryo stages and gamma ray doses. The highest percentage of haploid production was 1.30% for genotypes 281. Point and arrow-like embryos were more likely to produce haploid plants. Meantime the percent of point and arrow-like embryos and the numbers of all embryo shapes were the highest when their ray doses were 80-100 Gy. Stick-shape embryo gave the best result, in which the plants regeneration rate and survival percentage were 83.33% and 35.71%, respectively. The optimum dose-rate was 45.19 Gy.min-1.
