Abstrak Evaluasi karakter morfologi akar telah dilakukan untuk menentukan karakter morfologi akar yang potensial sebagai indikator adanya kekurangan air pada padi ( Oryza sativa L.) di antara panjang akar, volume akar, berat basah akar, berat kering akar, rasio akar:tajuk dan rasio panjang akar:tinggi tanaman. Eksperimen ini dilakukan di rumah kaca dan menggunakan 2 varietas padi (Superwin dan IR 64) pada fase vegetatif  yang ditumbuhkan pada media tanah di polybag dengan perlakuan kekeringan (tidak disirami selama 14 hari) dan disirami sampai kapasitas lapang (kontrol). Panjang akar dan rasio panjang akar:tinggi tanaman dapat dijadikan indikator kekurangan air pada padi Superwin dan IR 64. Superwin yang merupakan padi sawah dapat dipertimbangkan untuk ditanam di lahan kering. Kata kunci: indikator, kekeringan, morfologi akar Abstract Root-morphological characters in rice ( Oryza sativa L.) were evaluated to determine the potential characters as water-deficit indicators among the length, volume, fresh weight, dry weight, ratio root:shoot and ratio root length:plant height. The experiment was conducted in the glasshouse using 2 rice varieties (cv. Superwin and IR 64) grown in the soil mixture at the vegetative phase. The treatments in this experiment were water deficit (without water for 14 days) and well-watered (watering until field capacity). The root length and ratio root length:plant height were potential as water- deficit indicators in Superwin dan IR 64. The upland rice, Superwin, should be considered to be cultivated in the water limited area. Keywords: drought, indicator, root morphology
