Abstract
The effect of induced chromosome asymmetry on the interchromosome correlations for chiasma formation was studied in the interchange heterozygotes of rye, Secale cereale L. Correlation for chiasma formation between two groups of chromosomes were observed only in 2 out of 18 plants studied. The estimates of between and within nuclear variances indicated negative correlation in these plants. The remaining 16 plants did not show interchromosome effect for chiasma formation.
