Abstract:

Study on the morphological variations among the populations of Meloidogyne incognita from nine districts of Assam exhibited variations only in the tail shape, while other morphological characters showed similarities among the populations.Tail shape of second stage juveniles (J2) of M.incognita collected from Golaghat, Kokrajhar, Nagaon and Sibsagar district was similar in shape. Likewise, J2 tail shape of Dibrugarh, Jorhat and Lakhimpur population showed similarity but, Dhubri and Kamrup population showed variation from other populations. No variation was observed in size and shape of perineal pattern of M. incognita collected from nine districts of Assam. Studies on morphometric variations (body length, stylet length, lip height, lip width, MB, a, b, b´, c and c´) among the populations of M. incognita from nine districts of Assam showed no distinct variations in the major characters, except in MB value. MB value of Kamrup population was higher (61.79) than other populations.
