Cytogenetic analysis of 189 green plants regenerated by anther culture in vitro was performed for Triticum aestivum L. A haploid number of chromosomes (2n=3x=21) was found in 49.2 of the examined pollen plants, while 41.3 of the plants had a diploid number of chromosomes (2n=6x=42) in their somatic cells. This means that 90.5 of the green pollen plants were either polyhaploids or hexaploids. Haploaneuploids i.e. polyhaploids with 2n=19, 20 or 23 chromosomes, occurred in the frequency of 2.1, while the frequency of diploaneuploids (hexaploids with 2n=40, 41, 43 or 44 chromosomes) was 4.2. Only 2 polyploids were found: one with 2n=8x=56, and one with 2n=9x=63 chromosomes, which was 1.1 of the total number of analysed pollen plants. Also, there were 2.1 of mixoploids, i.e. plants which contained somatic cells with haploid and diploid numbers of chromosomes.
