Abstract
A 3-h treatment period with 0.2 per cent colchicine on 1-week-old seedlings of inbred lines of Italian ryegrass (Lolium multiflorum L.) has long-range effects on chromosome behaviour at meiosis. There is a reduction of mean pollen mother cell chiasma frequency, an increase in univalents and in cell and bivalent variances, and also changes in the pattern of chiasma distribution within bivalents. The effects are seen in the generation in which the treatment is given, and in the following sexual generation.
