Biochemical changes in black gram varieties inoculated with root-knot nematode, Meloidogyne incognita were investigated. Observations were recorded in the biochemical modifications relating to various parameters like total chlorophyll , total sugar contents, protein, and  proline content during post infection periods. The variation in total chlorophyll, total protein, proline and total sugar content  in six cultivars i.e   PU 09-36(S), MU-44(S) ,VBG 11-031(R) ,VBG 11-016(R) ,KUG- 715 (R)and NUL- 205(R) were studied 45 days after inoculation . Reduced percentage of total chlorophyll contents were observed in inoculated samples than the  healthy counterparts. However, an increase in amount of total  protein ,proline  and total sugar contents was observed in the diseased tissues.
