Studies developed in Brazil with the mume (Prunus mume Sieb. et Zucc.) have shown promising perspectives of using this species as rootstock for peach and nectarine trees, in function of its rusticity, adaptation to soft winter, compatibility with Prunus persica, plant vigor reduction and improvement of the fruit quality. However, due to seed propagation, vigor differences have been observed among plants, resulting in very heterogeneous orchards. Thus, the present study had the objective of studying the rooting of herbaceous cuttings of four mume clones (Clones 02, 05, 10 and 15) in intermittent mist during the soft winter, in Jaboticabal, São Paulo State, Brazil. The experiment was carried out between June and August, being evaluated 70 days after the cutting. From the obtained results, it was possible to conclude that the propagation of the clones studied is viable through the rooting herbaceous cuttings during the winter. Differences were observed among the clones with relationship to rooting percentage, callus percentage, root number and length. Grouping all the analyzed variables the best results were obtained with the Clones 10 and 15.
