Abstract
The objective of this work was to assess the effect of six rootstocks on yield, fruit quality, and growth of 'Oneco' mandarin during the first seven harvesting seasons, in Butiá, Rio Grande do Sul State, Brazil. The rootstocks evaluated were: 'Swingle' citrumelo (Citrus paradisi × Poncirus trifoliata), 'Caipira' orange (C. sinensis), 'Troyer' citrange (C. sinensis × P. trifoliata), 'Rangpur' lime (C. limonia), 'Volkamer' lemon (C. volkameriana), and 'Flying Dragon' trifoliata orange (P. trifoliata var. monstrosa). Plants budded onto 'Flying Dragon' had the lowest vegetative development, which indicates the dwarfing characteristics of this rootstock, and had the highest mean production efficiency, despite low yield. Plants grafted on 'Volkamer' lemon and 'Rangpur' lime had the highest alternate bearing. Under the experimental conditions evaluated, the most adequate rootstocks for mandarin 'Oneco' are 'Swingle' citrumelo and 'Troyer' citrange, regarding fruit yield and quality.

The objective of this work was to assess the effect of six rootstocks on yield, fruit quality, and growth of 'Oneco' mandarin during the first seven harvesting seasons, in Butiá, Rio Grande do Sul state, Brazil
'Oneco' mandarin was budded onto six rootstocks: 'Swingle' citrumelo [Citrus paradisi Macfad × P. trifoliata], 'Caipira' orange (C. sinensis Osbeck), 'Troyer' citrange (C. sinensis × P. trifoliata), 'Rangpur' lime (C. limonia Osb.), 'Volkamer' lemon (C. volkameriana Ten. & Pasq.), and trifoliata 'Flying Dragon' orange [P. trifoliata var. monstrosa
Summary
'Oneco' mandarin (Citrus reticulata Blanco) is a selection of 'Ponkan' mandarin, which occupies 58% of the mandarin‐producing area in Brazil (Amaro & Caser, 2003). There is a lack of information on the effects of different rootstocks on 'Oneco' mandarin fruit quality, tree development and productivity. Rootstocks affect canopy growth and development, production, and fruit quality in citrus, as well as tolerance to various stresses (Castle, 1987). To which rootstock resistance is crucial, has prompted the need to investigate rootstock assortment. Diseases, such as citrus tristeza virus, gummosis (Phytophthora sp.), and citrus sudden death, reinforce the call for research on diverse citrus species and hybrids as potential rootstock material. The objective of this work was to assess the effect of six rootstocks on yield, fruit quality, and growth of 'Oneco' mandarin during the first seven harvesting seasons, in Butiá, Rio Grande do Sul state, Brazil
