Androgenous and regeneration abilities of 8 heterozygous wheat (Triticum aestivum L.) genotypes were analyzed in anther culture. Cytological characteristics of green regenerants were also analyzed. Significant differences were found among the genotypes in their androgenous and regeneration abilities. The average androgenous capacity of all genotypes was 4.4% ranging from 0.7% (Prima/Hueguen) to 11.0% (NS173-98/NS164-98). The average callus yield was 8.7%. The genotype Banks/F53-70 produced the highest number of green plants (33 green plants), while the genotype Banks/Pobeda showed no green plant regeneration ability. The frequency of albino plants ranged between 0% (Banks/Rodna) and 5.3% (Anastasija/Radika). A total of 61 green and 61 albino plants were regenerated. The results of cytological analysis showed that, from the total number of regenerated green plants, 40.9% were haploids and 59.1% were spontaneous double haploids
