Induced desynapsis in Capsicum annuum L.

The seeds of Capsicum annuum L. were treated with 0.5% aqueous solution of MMS for 3, 5 and 6 h. During the cytological studies 2 desynaptic plant were isolated at 6 h treatment. In plant-1, average number of univalents and bivalents per cell were 13.00 and 6.50, at diakinesis and 15.80 and 4.52 at metaphase-I, while in plan-2 it was 6.12 and 9.20 at diakinesis and 10.80 and 7.80 at metaphase-I. At anaphase, equal distribution of chromosome was observed only in 7.89 and 11.42% pollen mother cells (PMCs) in plant-1 and plant-2 respectively. Rest of PMCs shows irregular distribution of chromosomes to the poles. Laggards at anaphase and micronuclei at telophase were also recorded. The desynaptic obtained during the present investigation, fit into the medium strong type with reduced pollen fertility.
