Abstract:

To study the intra-specific morphological and morphometric variations of Meloidogyne graminicola, rice roots having galls were collected from three different localities of southern part of West Bengal during 2014-2015. All the root gall inducing nematodes of rice from Chakdah, Habra-II and Egra-II areas of West Bengal were identified as Meloidogyne graminicola Golden and Birchfield, 1965. All the populations or isolates of M. graminicola collected from rice growing areas of West Bengal revealed that second stage infective juveniles from Gayeshpur localities of Chakdah block of Nadia district exhibited high level of variability with regard to body length, tail length, tail terminus and ‘a’ value; while J2 from those of Ramkrishnapur (Egra-II of East Mindapore district) and Mena (Habra-II of North 24 Parganas district) areas had close morphometric similarity. Morphometric features of all the isolates of the second stage juveniles of M. graminicola associated with rice in West Bengal revealed close adherence with all the key diagnostic features of M. graminicola. There is an immense scope of further work with all the isolates of M. graminicola collected from rice growing areas of southern parts of West Bengal. Here, only morphological and morphometric variability of M. graminicola had been studied. Difference in biology, host nematode interaction, races (if any), biochemical and molecular differentiation among those isolates can be explored in future.
