Fourteen tuberose (Polianthes tuberose L) cultivars were evaluated under filed condition to understand their performance against foliar nematode (Aphelenchoides besseyi Christie). Significant differences were recorded among the tested cultivars for their yield attributing parameters as well as nematode population in flower samples. However, the height stalk length obtained from the cultivar Sikkim Selection while maximum spike length was recorded from Prajwal (33.79 cm). The cultivar Vaibhav was recorded maximum number of florets per spike (26.45) and maximum percentage of infestation was estimated in cultivar GKTC Hyderabad (79.48%) followed by Single Hyderabad (79.48%) and Bidhan Rajani-III (78.65%). However, minimum number of nematode population was registrant the cultivar Phule Rajani and Prajwal respectively. Symptom appearance in tuberose due to profuse feeding on the stalk epidermis as a result stalk became irregular and rugged, spiny structures of variable number were found on the surface of the flower stalk along the length. Sometimes spike developed but the florets did not bloomed or partial bloomed of either lower most or the top most few florets. In few cases the flower stalk emerged with a blind flower head where no spike developed.
