Preliminary Identification of Local Maize Under Drought Stress By PEG-6000

Adaptation test of local maize plants under drought stress requires early selection at the seedlings stage through Poly Ethylene Glycol (PEG-6000). This study aimed to identify local varieties of maize plants from North Sumatra under drought stress with several doses of PEG-6000. This study was conducted from July to November 2022 using a completely randomized design with two factors and three replications. The sixteen local maize (L) and a hybrid variety (H) of maize as a comparison were used as the first factor. The PEG doses were 0; 100; 200; 300; 400; and 500 g L-1 as the second factor. Data were analyzed using analysis of variance and duncan's multiple range test at P
