Abstract

The sustainability of rice production depends on the development of new rice cultivars with high yield and stable performance. The choice of cultivar more suited to a particular environment can contribute to increased productivity of this crop. The aim of the present study was to evaluate the agronomic and yield characteristics of some breeding lines of amphibious rice. The experiment was conducted in Konawe, Southeast Sulawesi, using a randomized block design with four replications. Eight breeding lines were used as single treatment. We evaluated the following agronomic characteristics: plant height, leaf area, tillering per hill, grains number per panicle, 1000 grain weight, and grain yield per hectare. Significant variation on agronomic and yield characteristics was observed among the amphibious rice lines. Greater tillering, higher grains number per panicle, and higher grains yield ha-1 were obtained on three amphibious rice lines, i.e., GS16-1, GS44-2, and GS11-2. Grain yield was observed to be positively associated with productive tillers, filled grains and number of grains per panicle.
