Early Test of the Tolerance of Upland Rice to Drought in the Germination Phase

Climate change in the form of drought will reduce agricultural production, so it is necessary to develop superior drought-tolerant varieties. The study aimed determine local upland rice cultivars at germination stage. From September December 2021, was carried out Seed Science and Technology Laboratory, Faculty Agriculture, Tadulako University, Palu, Center Sulawesi, Indonesia. A completely random design (CRD) with a two-factor factorial pattern employed study. Twelve comprised first factor, while two drought-resistant variants served as comparators. second factor osmotic stress, namely P0 = control, P1 -1 bar, P2 -2 P3 -3 there are 56 treatment combinations repeated four times, 224 experimental units. observed variables were maximum growth potential, rate, radicle length, plumule dry weight, sprout water volume, rate. results showed that stress through PEG – 1 bar did not affect germination. Using down resulted significant reduction Pulut ko, logi sina ponding have tolerance stress.
