Stagnant water is an environmental challenge that can have a negative impact on tobacco growth and productivity. Study on waterlogging-tolerant tobacco is still limited. Flood-resistant tobacco genotypes are needed for future agriculture. The aim of this study is to select tobacco genotypes that are tolerant to waterlogging. This study used a factorial randomized block design. The control treatment was 100% waterlogging, with subsequent treatments escaLating to 120%, 140%, and 160% (Filed capacity). Waterlogging was given for 75 hours. The observation indicator is the level of wilting of tobacco leaves. Based on the stress index values obtained from the thirty-three tested genotypes, there are three categories of ability to withstand waterlogging, namely, tolerant, moderate and sensitive. Based on the results of the study analysis, it can be interpreted that the Bojonegoro 1 genotype is the only genotype that is included in the category of tolerant to waterlogging. Genotype 1 Bojonegoro was able to survive up to 73 hours with stress sensitivity index score of 0.21.
