Pineapple is a tropical fruit that has high economic value. Mutation is one method to increasing diversity of plant and plays an important role in plant improvement. This study aims to induce mutation in pineapple used colchicine. This study was arranged using a factorial completely randomized design, which the first factor was four pineapple genotypes, and the second factors was four colchicine concentration levels. Observation parameters included leaf shape, leaf color, plant height, number of leaves, leaf width, number of stomata, stomata length and stomata width. The results of this study showed that genotype has a significant difference on all parameters. The concentration of colchicine only had a significant effect on stomatal length. The interaction between genotype and colchicine had a significant difference on plant height and number of leaves. The conclusion of this study was that colchicine caused a decrease in plant height and an increase in leaf number and stomata length.
