Abstract In order to increas the yield of Zizania latifolia，it is necessary to find a quick method to
distinguish unpregnant plants. Based on comparing the main differences among internal structure of normal swollen
culms，swollen culms with Ustilago esculenta and unpregnant plants of Zizania latifolia，this paper verified the
relationship between the difference of culm internal structure and formation of Zizania latifolia by field experiment.
The results showed that culms with filaments were pregnant，all belonged to normal swollen culms，swollen
culms with Ustilago esculenta；and culms without filaments were not pregnant，all belonged to unpregnant plants
of Zizania latifolia. These results indicated that unpregnant plants will be distinguished by finding if there was
filaments inside of the medullary cavity of culms. This is a new method for quickly and efficiently distinguishing
unpregnant plants of Zizania latifolia.
