Screening for resistance to powdery mildew on accessions of cutleaf groundcherry

Cutleaf groundcherry (P. angulata L.) is a wild plant that is utilized as traditional medicine. Agroindustry raw materials for biopharmaceuticals require constant production in both quantity and quality. Powdery mildew (Podosphaera sp.) typically damages all areas of cutleaf groundcherry plant, lowering plant quality. Universitas Brawijaya has cutleaf groundcherry accessions from all throughout Indonesia.

The study's goal was to screen powdery mildew resistance of cutleaf groundcherry accessions. The study was conducted in greenhouse of the Experimental Field Faculty of Agriculture, Universitas Brawijaya in Jatimulyo, Lowokwaru, Malang City. The experiment took place between June-August 2021. The research materials included 100 accessions cutleaf groundcherry, polybags, soil media, and fertilizer. The experiment was using randomized block design (RBD) with three replications. Each accession in one plot had three plants, for a total of nine plants throughout all replications.

At 14 dap plants showed responses to powdery mildew ranging from 0% to 55.6%. Based on disease incidence, it can be determined that 49 accessions were very resistant (0.00%), 29 accessions were resistant (1-20%), 21 accessions were moderately resistant (21-40%), 1 accession was moderately susceptible (41-60%). Based on this research, cutleaf groundcherry accessions were obtained as raw materials for biopharmaceuticals that are resistant to powdery mildew.
