'Michal' tangerine (Citrus clementina x C. tangerina) can be a good choice as canopy for early maturing fruit production in Rio Grande do Sul. The limitation is the lack of information about its performance and management. The aim of this research was to evaluate the development, production and fruit quality of 'Michal' tangerine grafted on five rootstocks: 'Troyer' citrange, 'Swingle' citrumelo, 'Cravo' lemon, 'Sunki' tangerine and 'Flying Dragon' trifoliate orange, in the Depressão Central of Rio Grande do Sul. The following variables were evaluated: plant height; trunk circumference; canopy projection area (APC); produced fruit number and weight (MF); MF/APC relation (IP); juice total soluble solids (SST) and total titrable acidity (ATT); fruit size and juice content. 'Swingle' citrumelo provided good vigor, yield, IP, SST and ATT for 'Michal', while 'Cravo' lemon induced good vigor, yield, IP and fruit size. Both are good recommendations as rootstock for orchards of 'Michal'.
