“…Trees on “Swingle” citrumelo grow vigorously and show a trunk overgrowth near to the grafting union ( Castle et al, 1988 ). Similar overgrowth has been observed for “Okitsu” satsuma mandarin and “Navelina,” “Jaffa,” “Cadenera,” and “Salustiana” sweet orange trees grafted on “Swingle” citrumelo ( Tazima et al, 2013 ; Bacar et al, 2017 ; Domingues et al, 2018 ; Cruz et al, 2019 ; Carvalho et al, 2021 ).…”

“…This last trait has gained more attention due to climate changes and the need for plants to adapt to a wide range of environmental conditions ( Alfaro et al, 2021 ; Aparicio-Durán et al, 2021 ). However, the susceptibility of “Rangpur” lime to some diseases has raised concerns and need to search for new alternative rootstocks for the Brazilian citrus industry ( Pompeu Junior and Blumer, 2014 ; Fadel et al, 2018 ; Carvalho L. M. et al, 2019 ; Carvalho S. A. et al, 2019 ; Carvalho et al, 2021 ).…”

“…“Fepagro C-13” citrange is mostly used in Southern Brazil. This rootstock enhances the fruit yield and quality of the scion, besides being tolerant to some detrimental diseases and cold ( Leite Junior, 1992 ; Stenzel et al, 2003 ; Pompeu Junior and Blumer, 2014 ; Carvalho et al, 2021 ).…”

Rootstocks modulate several characteristics of citrus trees, including vegetative growth, fruit yield and quality, and resistance or tolerance to pests, diseases, soil drought, and salinity, among other factors. There is a shortage of scion and rootstock cultivars among the combinations planted in Brazil. “Ponkan” mandarin and “Murcott” tangor grafted on “Rangpur” lime comprise the majority of the commercial mandarin orchards in Brazil. This low genetic diversity of citrus orchards can favor pest and disease outbreaks. This study aimed to evaluate the agronomic performance, Huanglongbing (HLB) tolerance, and fruit quality of “Emperor” mandarin on five different rootstocks for nine cropping seasons under the subtropical soil-climate conditions of the North region of the state of Paraná, Brazil. The experimental design was a randomized block, with six replications, two trees per block, and five rootstocks, including “Rangpur” lime, “Cleopatra,” and “Sunki” mandarins, “Swingle” citrumelo, and “Fepagro C-13” citrange. The evaluations included tree growth, yield performance, fruit quality, and HLB disease incidence. “Emperor” mandarin trees grafted on “Rangpur” lime and “Swingle” citrumelo had early fruiting and high yield efficiency. “Rangpur” lime also induced the lowest tree growth, but low fruit quality. Trees on “Swingle” citrumelo and “Fepagro C-13” citrange showed low scion and rootstock affinity and produced fruits with high total soluble solids (TSS), with a lower number of seeds for those from trees on “Fepagro C-13” citrange. “Cleopatra” and “Sunki” mandarins induced higher juice content, while fruits from trees on “Cleopatra” also had higher TSS/titratable acidity (TA) ratio. “Emperor” mandarin trees were susceptible to HLB regardless of the rootstocks. Overall, “Cleopatra” and “Sunki” mandarins, “Swingle” citrumelo, and “Fepagro C-13” are more suitable rootstocks for “Emperor” mandarin under Brazilian subtropical conditions than “Rangpur” lime.

“…Hybrid and clonal rootstocks from Brazil and other countries are evaluated for nursery performance ( Marques et al, 2021 ), drought ( Santana-Vieira et al, 2016 ), and tree size control ( Costa et al, 2021 ). Numerous field trials have been used to compare performance of the many rootstocks, with superior rootstocks identified for the different production situations ( Cantuarias-Avilés et al, 2010 ; Girardi et al, 2017 ; Carvalho et al, 2019 ; Costa et al, 2020b ; de Carvalho et al, 2021 ). Focused studies were conducted to map quantitative trait loci (QTL) in citrandarins associated with host response to infection by CLas ( Soratto et al, 2020 ) and Phytophthora parasitica ( Lima et al, 2018 ), and to identify mechanisms of tolerance to HLB ( Curtolo et al, 2020 ).…”

SuperSour: A New Strategy for Breeding Superior Citrus Rootstocks

2021

View full text Add to dashboard Cite

Citrus crops have a long history of cultivation as grafted trees on selected rootstock cultivars, but all current rootstocks have significant limitations and traditional methods of rootstock breeding take at least 2–3 decades to develop and field test new rootstocks. Citrus production in the United States, and other parts of the world, is impaired by a wide range of biotic and abiotic problems, with especially severe damage caused by the disease huanglongbing (HLB) associated with Candidatus Liberibacter asiaticus. All major commercial citrus scion cultivars are damaged by HLB, but tree tolerance is significantly improved by some rootstocks. To overcome these challenges, the USDA citrus breeding program has implemented a multi-pronged strategy for rootstock breeding that expands the diversity of germplasm utilized in rootstock breeding, significantly increases the number of new hybrids evaluated concurrently, and greatly reduces the time from cross to potential cultivar release. We describe the key components and methodologies of this new strategy, termed “SuperSour,” along with reference to the historical favorite rootstock sour orange (Citrus aurantium), and previous methods employed in citrus rootstock breeding. Rootstock propagation by cuttings and tissue culture is one key to the new strategy, and by avoiding the need for nucellar seeds, eliminates the 6- to 15-year delay in testing while waiting for new hybrids to fruit. In addition, avoiding selection of parents and progeny based on nucellar polyembryony vastly expands the potential genepool for use in rootstock improvement. Fifteen new field trials with more than 350 new hybrid rootstocks have been established under the SuperSour strategy in the last 8 years. Detailed multi-year performance data from the trials will be used to identify superior rootstocks for commercial release, and to map important traits and develop molecular markers for the next generation of rootstock development. Results from two of these multi-year replicated field trials with sweet orange scion are presented to illustrate performance of 97 new hybrid rootstocks relative to four commercial rootstocks. Through the first 7 years in the field with endemic HLB, many of the new SuperSour hybrid rootstocks exhibit greatly superior fruit yield, yield efficiency, canopy health, and fruit quality, as compared with the standard rootstocks included in the trials.
