Type: article
Abstract: Lodging on rice plants was one of the causes of decreased rice plant production. Developing superior local varieties through crossing was one of the solutions to address the decrease in the production of rice plants. This research aims to know and determine the potential of F8 lines of lodging varieties of upland rice. This research was conducted using an experimental method. The design used a randomized block design with 10 treatments (5 F8 lines and 5 comparison varieties). The F8 lines used G1, G2, G3, G4, and G5. The comparison varieties used were Danau Gaung, Inpago 8, Inpago 12, Rindang, and PBM UBB 1. The research data were analyzed using Duncan Multiple Range Test (DMRT), correlation test, and pathway analysis. The result showed that F8 lines of upland rice had a potential yield of 2.350 tons/ha to 3.395 tons/ha in the dry land of Belitung. The correlated characters were the weight per plot and the flag leaf length in the pathway analysis. White rice of upland rice lines had the highest yield potential in the dry land of Belitung was G4 in the amount of 6.79 kg/plot, and the yield potential of red rice lines was G5 in the amount of 6.72 kg/Plot.
