Abstract

The soluble protein in healthy resistant RGC-986 was highest followed by moderately resistant RGC-1003 while it was lowest in susceptible cv. RGC-936. Maximum decrease in soluble protein due to infection was observed in susceptible followed by resistant and moderately resistant cultiver. Total phenols were higher in healthy leaves of resistant followed by moderately resistant. The total phenolic contents were highest in diseased leaves of resistant cv. RGC-986. Total sugars was maximum in Alternaria blight infected leaves in resistant followed by susceptible and was lowest in moderately resistant. The similar trend was also found in non reducing sugar. But in case of reducing sugar, the maximum decrease was observed in susceptible as compared to healthy leaves in all three cv. of cluster bean.
