Abstract

Of late, rice root-knot nematode Meloidogyne graminicola has become a serious menace in all type of rice situations in India. A field study was under taken during kharif-2013 to evaluate 135 landraces (local cultivars) collected and maintained at Organic Farming Research centre of ZAHRS, Navile, Shimoga against Meloidogyne graminicola. The result reveals that the varieties show varying degrees of responses. Out of 135 cultivars, 32 cultivars were found to be highly resistant, while, 45 varieties read were resistant. However, 40 varieties were evaluated to be moderately resistant and nine varieties susceptible. The remaining nine cultivars were learnt to be highly susceptible.

Key word: Rice, root-knot nematode.
