Evaluation of some common rice varieties of Manipur for resistance against rice root-knot nematode

Author(s): L. Joymati Devi
Abstract: Screening of some common rice varieties of Manipur were tested for their resistance against rice root-knot nematode (Meloidogyne graminicola). The investigation was conducted on 10 varieties, which showed evidence of damaging potential of Meloidogyne graminicola in terms of plant growth parameters and disease incidence. Disease intensity grade was classified on the basis of root knot index. All the varieties were susceptible to Meloidogyne graminicola except Dharam and Tampha which were resistant. Maximum number of root galls (45) were recorded in rice variety Lamyanba whereas minimum root galls (2) were recorded in rice variety Dharam.
