Maize (Zea mays L.) is a crop in a tropical region which resists growing under sensitive temperature. This study wasconducted to evaluate the performance of Canadian maize inbred lines under controlled cold stress conditions (5℃, 10℃, and 23℃). Data were recorded by measuring germination rate, index, root length, and seed vigour index values. Five higher and three lowertolerant inbred lines were shortlisted. The data were analyzed using analysis of variance, while mean values were compared usingTukey’s Honest Significant Difference Test at α=0.05 and at α=0.01. Using Genstat software, correlation was done. A strongcorrelation (P＜0.05) was found between germination rate and germination index under all stress conditions. Root length and vigourindex were also strongly correlated with germination rate under 5℃ stress condition and compared to 10℃ and 23℃ stress conditions. Our results suggested that five (CO439, CO438, CO450, CO435, and CO445) among 22 maize inbred lines performed better under 5℃cold stress condition and thus had the potential to develop maize hybrids to increase grain yield under environmentally stressfulconditions in South Korea.
