The cytology of bread wheat (Triticum aestivum) suspension lines, recycled lines (selected for high division frequency) and their dividing protoplasts, have been examined. Extensive numerical and structural chromosome variation was present in all the lines. The most frequently observed chromosome numbers were around 2n=32, indicating that considerable chromosome loss from the normal wheat complement (2n=6x=42) had occurred during selection of the lines. Chromosome aberrations also indicated loss of chromosome arms and chromosome segments. The implications of this variation for studies on transformation and for the potential regeneration of whole plants from protoplasts of bread wheat are discussed.
