Abstract: The objectives of the research were to obtain information of genotype x environment interaction, yield potential, adaptability and stability of up land rice lines obtained from crossbreeding between landrace upland rice from Buru Island and new plant type of lowland rice. Ten lines and two cultivars were planted at seven different locations in November 2010 - March 2011, used randomized complete block design with four replications. Observation was done on grains weight per hectare. Estimation stability used two yield stabilities analysis, Finlay and Wilkinson, and Additive Main Effect Multiplicative Interaction (AMMI). The results showed that genotype x environment interaction factors contributed to yield variance by 16.6%. The highest productivity was achieved by FM1R- 1-3-1 (4.52 tons ha-1). Genotypes FG1R-30-1-5, FG1-65-1-2, FG1R-30-1-3 and FG1R-30-1-1 were dinamic stable and poorly adapted to all environments. Genotype FG1-70-2-1, FG1R-36-1-1, FG1R-30-1-4 and FG1- 6-1-2 were specifically adapted to unfavourable environments. Genotypes FM1R-1-3-1, Fat-4-1-1, Situ Bagendit and Towuti were specifically adapted to favourable environments.
