Abnormal spindle behaviour in induced autotetraploid, Physalis pubescens L.

In the colchicine induced autotetraploid Physalis pubescens L., meiotic spindle abnormality was observed in one plant. It is probable that the colchicine treatment may have disturbed the spindle organiser, thereby causing abnormal spindle behaviour. The genetic basis for this abnormality (multipolar spindle) could not be established on account of lack of seed set in the plant showing the abnormal spindle behavior.
