Abstract
The pairing of standard B chromosomes in rye plants with a small iso B or deficient B chromosome and several standard B chromosomes, namely, the 2 stB + 1 siB plant, the 2 stB + 1 defB plant and the 4 stB + 1 defB plant, was observed in comparison with the 2-5 stB plants and with the 2 stB + 1 liB plant. Frequencies of pairing of standard B chromosomes in the former 3 plants were considerably lower than those in the later plants. The presence of the small iso B or the deficient B chromosome reduced the amount of pairing between standard B chromosomes. This was possibly due to the deficiencey of a special distal segment of the long arm of the standard B chromosome.This publication has 3 references indexed in Scilit:
