Abstract : Percentage Disease Index(PDI) is an ideal tool for determining the disease severity among a plant population. Disease severity caused by the pathogen Albugo candida was conveniently estimated. The resistant response of the different Brassica cultivars was varied yet interesting care was taken while preparing the disease scale. It was common for all cultivars. The period of study extended between 7-42 days after sowing.
