ABSTRACT
Exploration of the potential resilience of local rice cultivars could be one strategy to overcome drought.
This study was aimed at selecting local drought-resistant rice cultivars. The result showed that drought
stress significantly reduced the morphological characters. The morphological analysis of plants (plant
height, the number of productive tillers, panicles and grain weight per clump) showed that Jelitheng
Karanganyar had the best characteristics for tolerating drought. The highest proline content during
drought conditions was in Wonogiri black rice. Based on screening, Salatiga black rice and Sragen black
rice showed a high-stress tolerance index (STI) values and were identified as drought-tolerant cultivars
at 70% FC.
Key words : Black rice, drought, proline, red rice, stress tolerance index
