abstract
Biochemical alterations brought about in resistant and susceptible cultivars of cowpeaas a result of root-knot infection was estimated in roots uprooted after 45 days of Meloidogyne incognita inoculation. Quantitative analysis of protein metabolites in resistant varieties such as Arka variety, IT-35956-1 and TVX-944 cultivars showed that protein content increased by 42.81 per cent, 89.93 per cent and 57.67 per cent respectively, in diseased roots. Similarly, in leaves of inoculated susceptible varieties like KM-5 and Gomati, protein content was highly reduced by 63.10 per cent and 52.27 per cent, respectively.
