Production of 'Valência' sweet orange on 41 rootstocks in the north of the state of São Paulo, Brazil

Abstract: The objective of this work was to select alternative rootstocks to 'Rangpur' lime for 'Valência' sweet orange scions in the northern region of the state of São Paulo, Brazil, based on initial fruit yield. Forty-one rootstocks were evaluated in an experiment carried out in March 2007, in the municipality of Colômbia, in the state of São Paulo. The accumulated fruit yield of 'Valência' sweet orange was assessed in the 2009, 2010, and 2011 crop seasons. The rootstocks 'Sunki' mandarin x Poncirus. trifoliata 'English', 'Malvasio SRA 115' mandarin, 'C-13' “S” citrange, 'Sunki' mandarin x P. trifoliata 'Benecke', 'Valência Rhode Red' sweet orange + 'Volkamer' lemon, 'C-54-4-4 SRA 337' mandarin, 'Cleopatra' mandarin x P. trifoliata 'Rubidoux', and 'À Peau Lisse SRA 267' have potential to replace 'Rangpur' lime in the northern region of the state of São Paulo, Brazil.

摘要：本研究旨在基于初始果实产量，为巴西圣保罗州北部地区的‘瓦伦西亚（Valência）’甜橙接穗筛选可替代‘黎檬（Rangpur lime）’的砧木。试验于2007年3月在圣保罗州科隆比亚（Colômbia）市开展，共评估41份砧木材料。研究于2009、2010及2011三个种植季，对‘瓦伦西亚’甜橙的累计果实产量进行了测定。结果显示，‘Sunki’橘与枳（Poncirus trifoliata）‘English’的杂交种、‘Malvasio SRA 115’橘、‘C-13’"S"枳橙（citrange）、‘Sunki’橘与P. trifoliata‘Benecke’的杂交种、‘瓦伦西亚罗德岛红（Valência Rhode Red）’甜橙+‘沃尔卡默（Volkamer）’柠檬、‘C-54-4-4 SRA 337’橘、‘克利奥帕特拉（Cleopatra）’橘与P. trifoliata‘Rubidoux’的杂交种，以及‘À Peau Lisse SRA 267’，均具备在巴西圣保罗州北部地区替代‘黎檬’作为砧木的潜力。
