MEIOTIC ANALYSIS IN THE INDUCED MUTANTS OF ROSA HYBRIDA CV. FOLKLORE

Published on

Microsporogenesis was studied in rose. cv. Folklore and its twelve gamma-ray induced
mutants. Different types of meiotic irregularities,viz., multivalents, univalents,fragments,
laggards and anaphase bridges were commonly observed both in cv Folklore as well as in
its induced mutants. Maximum number of bivalents per PMC were recorded in Oimbing
Orange-White which was significantly higher than the mutants Solid Orange and Striped
Pinkish-Red, as compared to control. Higher meiotic irregularities in the induced mutants
may be due to complicated structural changes and alteration in karyotype which caused
variation in the morphology of the mutants.
 

Keywords: Rose, meiosis, chromosomal aberrations, induced mutants.
