ABSTRACT:

Meiotic details of a desynaptic plant of catharanthus roseus showed occurrence of a number of univalents at diakinesis and metaphase-I. Due to irregularity in the chromosomal behaviour, unequal separation, laggards and bridges and clumping of chromosomes were observed at anaphase-I. The desynaptic plants exhibited high sterility and reduced seed set. Desynapsis may be helpful in the genetic analysis of plants such as aneuploids.

KEYWORDS: Aneuploidy;  Desynapsis; Ethyl-Methane Sulphonate (EMS); Catharanthus roseus.
