The purpose of this study was to determine the appearance of black rice rice genotypes and their adaptation to two types of agroecosystems on dry land. The experiment used a randomized block design at each location with 3 replications and at each test 14 experimental plots were arranged. The treatment used 14 genotypes of black rice, namely: 2 elders (Situ Patenggang superior varieties and Baas Selem cultivars), and 12 lines of hope. Parameters observed were flowering age, plant height, number of productive and unproductive tillers per clump, leaf area, panicle length, number of filled grains and empty grains per panicle, weight of 100 grains, grain weight of each clump and grain yield. The results showed that there was no interaction between location and genotype on flowering age, plant height, number of productive tillers and unproductive tillers, panicle length, leaf area, number of filled grains per panicle, weight of 100 grains, grain weight per clump and grain yield , but interacts with the number of empty grains per panicle. The adaptation and stabilization test results showed that genotype G1 which was classified as stable which had general adaptation, and genotype classified as special adapted and very sensitive to environmental changes was G2; G3; G5; G6; G7; G8; G9; G10; G11; G13; and G14, whereas genotypes G4 and G12 are classified as special adaptation in marginal environments. Keywords: Location and genotype of black rice.
