Abstract

The aim of this research is to find out the tolerance level of Gorontalo local upland rice against drought stress given during the germination stage with vigor index and normal sprout dry weight variables as the indicators. The research was conducted in June 2016 using a completely randomized factorial design with four replications. The first factor is twenty-three varieties of Gorontalo local upland rice, while the second factor is 0%, 5%, 10%, and 20% PEG 6000 concentrations. The categorization of accessions to tolerant, moderate, and resistant groups is conducted based on sensitivity index test results. The research results show that based on the normal sprout dry weight, vigor index, and growth simultaneity parameters, Sonu, Ponda Merah, Ponelo, and Bulotonu accessions are tolerant against drought stress at 20% PEG concentration.
