Technical Abstract: The foliar nematode Aphelenchoides besseyi causes the white tip disease of rice and a floral malady in tuberose in West Bengal (WB), India. The same nematode is widely distributed in many other states of India, including Andhra Pradesh (AP) and Madhya Pradesh (MP) rice fields. In order to generate information on intraspecific variations of A. besseyi as well as to confirm the identity of the nematode species infecting two of the most important crops of India, morphological and morphometric observations were taken of A. besseyi isolated from tuberose and rice from WB and rice from AP and MP. The observed variations among the populations in the tail, esophageal and anterior regions, including the occurrence of four as well as six lateral lines in the lateral fields, could be regarded as a consequence of host-induced or geographical variations. Additional information regarding the distribution of this nematode on tuberose within the region is needed.
