Abstract:
Meiotic study was made on nine okra lines (Abelnioschus esciilentuf [L] Moench.) resistant
to yellow vein mosaic virus (YVMV), evolved by introgressing the resistant genes from A.
tetnphyllus (L.) Medic. The chromosome number of the lines varied from 2n = 120 to 144. All the
lines showed regular meiosis. The study confirmed the complex polyploidy in A. esculent us which
can sustain a considerable number of additions and deletions of chromosomes.
