Abstract: Electron microscopy of observing rye synaptonemal complex with cellspreading method and analyzing the synaptonemal complex karyotype of the rye cultivar, Victory, was for the first time covered in China. It suggests that there are two chromosomal translocations in the variety. A small fraction of long arm of 1R translocated onto the shorts arm of 6R, and 3 units of the percentage length have translocated from the long armof 4R onto the long arm of 2R, so that the long arm has become the sho-rt arm of 4R. Accordingly, it is believed that the rye cultivar, Victory, is a translocation heterozygote. Perhaps the method is useful in the studies on experimental texonomy of plant.
