Abstract: The present investigation was undertaken to study the chemical and biochemical parameters of selected powdery mildew resistant and susceptible genotypes of fenugreek. It is observed that the Kasuri selection - 2 was found immune, Purandar local-1 found moderately susceptible and Lasalgaon as highly susceptible. Rest of fifteen varieties were found susceptible. It is observed that the activity of polyphenol oxidase (PPO) and peroxidase (PO) enzymes were higher in immune variety (Kasuri selection-2) as compared to susceptible varieties before and after incidence of powdery mildew and has shown negative significant correlation (-0.766) for (PPO) and (-0.569) for (PO) after 80 DAS with PDI.
It is concluded that total chlorophyll content in immune variety was higher than susceptible varieties, before (40 DAS) and after (80 DAS) incidence of powdery mildew and has shown negative significant correlation (-0.654) and (-0.741) at 40 DAS and 80 DAS, respectively with PDI. The activity of polyphenol oxidase (PPO) and peroxidase (PO) enzymes were higher in immune variety (Kasuri selection-2) as compared to susceptible varieties before and after incidence of powdery mildew. The nitrogen concentration has direct relation with powdery mildew of fenugreek. However, there was no concrete relation with other macro or micronutrient concentration in fenugreek with powdery mildew disease.
