Tests are carried out to obtain red rice lines that are tolerant to drought based on morphological characters in the vegetative phase (49 HSS). The lines used were genetic material from red rice lines which were the result of a cross between local red rice cultivars namely karajut and silopuk cultivars with Fatmawati varieties consisting of 10 lines namely KF42-2-3, KF42-4-2, KF42-7-3, KF42-9-3, KF42-10-2, KF42-13-2, SF122-3-16, SF122-3-30, SF5-25-8 and SF-25-25. This experiment was carried out from January to May 2018 in the greenhouse of the Faculty of Agriculture, Andalas University. This experiment used a Randomized Block Design (RBD) consisting of 3 groups and 10 hope lines that were given drought treatment. The level of damage based on winding, and leaf dryness of the vegetative phase of all lines included in the tolerant category except SF122-3-30 with a somewhat tolerant category. Based on the intensity of leaf rolling consisting of 2 groups, the tolerant group consisted of 2 lines and rather tolerant groups consisting of 8 lines. Based on the leaf drought intensity consisting of 2 groups, the tolerant group consisted of 7 lines and rather tolerant groups consisting of 3 lines.
