 ABSTRACT

To study the comparative effect of M. graminicola on both types of rice, i.e., scented (var. Pusa 1121) and non-scented rice (PR 114), a screen house study was conducted to see the relationship between inoculum density of Meloidogyne graminicola, growth of rice plants and development of the nematode was carried out in three different types of soil (clay loam, sandy loam and loamy sand. Different inoculum levels used were 0 (non-inoculated check), 10, 100, 1000 and 10000 j2/kg soil. Plant growth parameters decreased significantly as inoculum levels increased from 100-10000 j2 irrespective of soil types indicating 100 j2 as damaging threshold level of M. graminicola on both types of rice. Plant growth was at par in 10 j2 and non inoculated check as compared to other inoculums levels. With each increase in inoculum levels from 10-1000 j2, nematode multiplication and reproduction was increased but decreased abruptly at 10000 j2. Maximum and significantly highest multiplication and reproduction was observed in 1000 j2 of M. graminicola.

Key words: Meloidogyne graminicola, scented rice, non-scented rice, pathogenicity, inoculum levels
