A study was undertaken in greengram [Vigna radiata (L.) Wilezek] varieties to assess biochemical changes of resistant and susceptible cultivars due to the root-knot nematode infection. The changes in nutrient profile in plants inoculated with nematodes caused reduction in chlorophyll contents. Chlorophyll ‘a’ was maximum decreased (96.36%) in resistant check variety 7GGG 10-14 followed by 93.98% in susceptible check variety 28 PM 10-12 but increasing trend was observed from 7.31 to 28.30% in 24ML-233 and 17 IPM 9901-6 varieties respectively. Chlorophyll ‘b’ was maximum decreased (61.81%) in susceptible check variety 29 PUSA-0672 followed by 53.33% in resistant check variety 7GGG 10-14 but increasing trend was observed from 3.031to 76.66% in 24ML-233 and 17 IPM 9901-6 varieties respectively. Total chlorophyll was maximum decreased (54.92%) in susceptible check variety 29 PUSA-0672 followed by 32.79% in susceptible check variety 28PM10-12 but increasing trend was observed from 6.031 to 86.27% in 24ML-233 and 17 IPM 9901-6 varieties respectively.
