INDUCED CHROMOSOME ASYMMETRY AND ITS EFFECT ON INTERCHROMOSOMAL CORRELATIONS FOR CHIASMA FORMATION IN RYE, SECALE CEREALE L.

Published on

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.
 

Keywords: Interchange heterozygote, chiasma, correlation, Secale cereale.
