The variation in total proline content in six greengram cultivars i.e., 24 ML-233 (R), 7 GGG 10-14 (R), 17 IPM 9901-6 (R), 8 GM 04-02 (R), 28 PM 10-12(S) and 29 PUSA 0672 (S) were studied 45 days after inoculation of Meloidogyne incognita. The total proline content in the shoots of both healthy and resistant cultivars was higher compared to the susceptible cultivars. However, in the inoculated plants the total proline content in four resistant variety varied from 100 mg/g to 150 mg/g as compared to two susceptible variety (90 mg/g to 140 mg/g) . An increasing trend was also observed in the proline contents in the shoots of inoculated susceptible and resistant cultivars.
