Abstract

The objective of this study was to estimate disease severity Cercospora Leaf Spot (Cercospora henningsii) and storage root rot of 11 cassava clones. The study was executed in the field research station of University of Lampung, Bandar Lampung from October 2016 to May 2017. Completely-randomized block design was used with three replications. The treatment consisted of 11 clones, i.e., Cimanggu, Bendo 3A , Duwet 3A, BL 1A , UJ 5, GM-1, UJ 3, Sembung, BL2, Batak , and Mulyo 3. Each experimental unit consisted 10 plants in per row; the planting distance were 100 x 50 cm. Clones Mulyo 3 dan Duwet 3 showed disease severity of Cercospora brown leafspot (1.3 dan 2.5%) less than UJ 3 and UJ 5; overall, the disease severity of all 11 clones was less than 7%, Clones Cimanggu dan Bendo 3A showed disease severity of root rot (1.4 dan 1.7%) less than UJ 3 and UJ 5. The disease severity of BL 2 was 74% (very susceptible). The range of the disease severity of root rot all 11 clones was 0 – 74%. Keywords: Cassava clones, Cercospora. Henningsii, brown leafspot, root rot
