Our results with three segregating pollen types from interspecific [F.sub.1] plants and the abnormal pollen morphology of the hypoploid pollen deficient for chromosome 12 clearly indicate that the pollen morphology, including the spine formation, in cotton is controlled, at least in part, by the haploid pollen nucleus.
Hyperploid plants accounted for 14% of the population and hypoploids made up 30%.
Aneuploids were present in both groups of regenerants; hyperploids (15 and 16 chromosomes) were more common among diploids while hypoploids (27 chromosomes) were more common among tetraploids.
