Study on the adaptability of barley lines to waterlogging condition was conducted during November, 1999 to March, 2000 at the Agronomy Farm, Faculty of Agriculture, Chiang Mai University. The study was conducted to evaluate the adaptability and growth development of 36 barley genotypes to waterlogging conditions using a split plot design with two levels of water application included regular irrigation and managed transient waterlogging during the growing period as main plots, and barley genotypes as sub plots. Main plot and sub plot treatments were arranged in three replications. Evaluation of flooding tolerance index (FI) for measuring the adaptability and growth development of 36 selected barley genotypes grown under waterlogging condition. The results showed that there were 13 barley to tolerant to waterlogging growing condition and gave FI not significantly difference with 1.0 value. In addition, FI value was positively correlated with root dry weight (r = 0.76), shoot dry weight (r = 0.84), total dry weight (r = 0.88), plant height (r = 0.61) and day of flowering (r = 0.43) but tiller and productive tiller per plant did not show any correlation with FI.
