Abstract

Meiosis in a highly sterile triploid clone of Jasminum grandiflorum Linn. was reported. Mean trivalent, bivalent and univalent frequencies were 7.85, 5.28 and 4.90 per cell respectively. Complete trivalent formation was observed in 1.22 per cent PMCs. On the basis of these observations, autotriploid nature of the present clone has been established. Reduction in frequency of trivalents and high frequency of univalents were attributed to small size of chromosomes or to desynaptic forces.
