Using two tetraploid wheat-rye F1 lines with and without 5B chromosome, it was examined whether the effect of high temperature (30°C) on homoeologous chromosome pairing varied or not depending upon the developmental stage of the treated PMCs. Experimental results clearly showed that the sensitive st...
