Abstract: The resistant reaction of the mononuclear heteroplasmic CMS lines with different cytoplasms to the whitebacked planthopper, Sogatella furcifera was studied preliminarily by means of honeydew measurement. Results revealed that the CMS line Guoguang 5A with the D type cytoplasm was resistant to S. furcifera remarkably.
