Synopsis Artificial polyploids exhibited the usual effects of chromosome doubling. Fiber perimeters and X‐ray angle increased apparently in the same proportion in the artificial Old World tetraploids, suggesting that polyploidy increases fiber thickness, but not length of helix in which the cellulose fibrils are deposited. In most samples of G. hirsutum octoploids, no such increase could be observed. In chimeras, leaf and seed epidermis (fibers) were sometimes derived from the same and sometimes from different cell layers.
