Screening of basmati rice germplasms against rice root-knot nematode, Meloidogyne graminicola

Abstract

The rice root-knot nematode infests rice plant and cause considerable yield loss to the tune of 17-30 per cent to rice cultivation. In order to identify resistant source, the field experiments were conducted during kharif-2014 and 2015 at crop research centre SVPUAT, Meerut to evaluate 50 basmati rice germplasms against Meloidogyne graminicola. The result revealed that the germplasms show varying degrees of responses. Out of 50 germplasms, Pusa 1637-18-7-6-20 was found to be resistant with scale 2, while, 2 germplasms Shaan (Hybrid) and UPR 3805-12-2-7 were evaluated to be susceptible with scale 4 in cropping season Kharif, 2014 and 2015.
