Demand for rice as a main food source of Indonesia's population continues to increase along with the population increase each year. An important input to increase rice productivity is the use of superior genotype. The good lines may be obtained through anther culture. This research was to study the agronomic traits and yield of doubled haploid lines of upland rice obtained from anther culture and compared to the check varieties Batutegi and Inpago 4. The study was conducted in field trials Babakan, University Farm, Bogor Agricultural University. Research was arranged in a randomized complete block design with four replications. Variables measured were vegetative plant height, generative plant height, number of vegetative tillers, number of productive tillers, flowering time, harvesting time, panicle length, number of pithy grain per panicle, number of empty grains per panicle, number of total grains, the percentage of pithy grain per panicle, the percentage of empty grains per panicle, weight of 1 000 grains, and grain yield per plot. The result showed that genotype gave very significant effect on the observed variables. There were lines whose productivity was higher than the check varieties: GM6, GM7, and GM8.
