Abstract
Abstract Prior knowledge of scion/rootstock combinations is essential for establishing appropriate citrus orchard management strategies. The objective of this work was to assess the initial yield and fruit quality among 228 scion/rootstock combinations set up in the municipality of Ibirapuã, extreme south of the state of Bahia in 2015. Harvests were carried out from April to August 2019, when trees reached 4 years of age. Number, total mass and cross-sectional diameter of fruits, productive efficiency, pulp yield, soluble solids content, titratable acidity and SS/AT ratio were evaluated. Statistical difference for all characteristics related to production and fruit quality regarding factors studied and their combinations was observed. Among ‘Pera’ orange clones, ‘Pera CNPMF A-15’/‘San Diego’ citrandarin and ‘Pera CNPMF D-3’/‘Riverside’ citrandarin combinations stood out. ‘Sincorá’ orange, in combination with ‘San Diego’ and ‘Indio’ citrandarins presented potential to be recommended to producers who wish to anticipate their harvests, as well as ‘Natal Ipeal’ orange in combination with ‘Indio’ citrandarin, in the sense of postponing them.
Highlights
Among mandarins, ‘Tropical Sunki’ stands out, which has as main characteristics high number of seeds per fruit, polyembryony degree close to 100% and greater tolerance to Phytophthora gummosis, compared to other selections of this mandarin (SOARES FILHO et al, 2002)
Scion varieties that presented the highest number of fruits per plant on the ‘Sunki Tropical’ (TST) mandarin were: ‘Pera’ CNPMF 01, B-12, D-6, D-9, E-6 and ‘Natal’ CNPMF 01 (Table 2)
Means followed by the same uppercase letter in the row and lowercase in the column do not differ by the Scott-Knott mean cluster test at 5% probability
Summary
Samples of six fruits per experimental plot were used, taken from the middle third of scions, packed in polyethylene bags, identified and taken to the laboratory. Scion varieties that presented the highest number of fruits per plant on the ‘Sunki Tropical’ (TST) mandarin were: ‘Pera’ CNPMF 01, B-12, D-6, D-9, E-6 and ‘Natal’ CNPMF 01 (Table 2). On ‘San Diego’ (SD) citrandarin were ‘Pera’ CNPMF E-6, E-3, ‘Olimpia’ and ‘Sincorá’. For ‘Pera’ CNPMF 01, D-3, E-3, ‘Olimpia’, ‘Bianchi’, ‘GE-03’, ‘Natal’ CNPMF 01 and 02, higher number of fruits per plant was observed on ‘Riverside’ (RIV) citrandarin and for ‘Pera’ GE-03 and ‘Sincorá’ on ‘Indio’ (IND) citrandarin. Cultivars with higher NTF in two of the rootstocks were ‘Pera’ CNPMF 01 and E-6, ‘Olimpia’, ‘GE-03’, ‘Sincorá’ and ‘Natal’ CNPMF 01. ‘San Diego’ (SD), ‘Riverside’ (RIV) and ‘Indio’ (IND) citrandarins [C. sunki × Poncirus trifoliata (L.) Raf.]
