Biochemical basis of resistance in chickpea varieties against the root-knot nematode, Meloidogyne incognita.

摘要

A pot experiment was conducted to study the biochemical difference among chickpea cultivars BGD 93, PUSA 256, PUSA 1108, PUSA 391, BG 1044, PUSA 1088, PUSA 1105 and PUSA 362. Biochemical assays (for peroxidase enzyme) were conducted on shoots of 45-day-old chickpea plants. The peroxidase activity in the shoots of chickpea cultivars showed that moderately-resistant cultivars had higher degree of peroxidase enzyme activity with maximum activity observed in resistant cv. PUSA 256. Minimum activity was observed in the case of susceptible cv. PUSA 362.
