Plant resistance against pathogenic fungi induced by PGPR seed priming involves multiple reaction pathways including accumulation of pathogenesis related hydrolytic enzymes such as chitinase and-1, 3 glucanase. So, the present investigation was conducted to study the pathogenesis related hydrolytic enzymes system induced by PGPR Pseudomonas fluorescens against wilt in chickpea varieties differing in susceptibility reaction. Chitinase as well as β-1, 3 glucanase activity in resistant variety JCP-27 and WR-315 showed maximum values compared to susceptible variety JG-62. The level of enzyme activity remained higher in tolerant variety throughout the disease developmental stages. The activity level of both the enzymes, chitinase as well as β-1, 3 glucanase were significantly induced by PGPR seed priming with Pseudomonas fluorescens in wilt sick treatment and was also leading to improve wilt resistance and reduced the seedling mortality including susceptible variety JG-62 against soil born wilt pathogen.
