Biochemical studies of host resistance against chickpea rust

Abstract

The experiment was conducted at Department of plant pathology, University of agricultural sciences, Raichur during 2018-19. Biochemical basis of host resistance was studied by analysis of total sugars and total phenols. Estimation of total sugars, reducing sugars, non reducing sugars and total phenols were done in samples from both healthy and rust infected leaf tissues of Annigeri-1, Bheema, JG11, Jaki, ICCL-86111 and ICC-3137 varieties of chickpea. The results reveled that, the activity of reducing and non reducing sugar content was decreased in all the genotypes when chickpea leaves were infected with Uromyces ciceris-arietini. Significant increase in the activity of phenol content was recorded when chickpea leaves were infected with U. ciceris-arietini.
