“…Although earliness is a characteristic of the scion, the rootstock may change the ripening development of orange fruits [30,33,35]; thus, rootstock selection plays a crucial role in new citrus orchards. The rootstock is an important component of a healthy and productive citrus tree, influencing the fruit yield, fruit quality, tree size, and tolerance of diseases [60,61].…”

The development of fruit ripening of ‘Valencia’ orange trees [Citrus sinensis (L.) Osb.] grafted on the following ‘Trifoliata’ hybrid rootstocks: ‘US-852’, IPEACS-256 and IPEACS-264 citrandarins, and F.80-3, ‘W-2’ citrumelo, and ‘Swingle’ citrumelo (control), was assessed in three different subtropical locations: Rancho Alegre (RA); São Sebastião da Amoreira (SSA); and São Jerônimo da Serra (SJS), Parana state, Brazil. The climate of the RA and SSA locations was classified as Cfa with hot summers, whereas that of the SJS location was Cfb with temperate summers, which are located at 380, 650, and 835 m a.s.l., respectively. A completely randomized block design with four replications and four trees per plot was used as a statistical model for each location. The soluble solids (SS) content, titratable acidity (TA), and the maturation index (MI) or ratio (SS/TA) of the juice, as well as the citrus color index (CCI) of fruit skin, were assessed monthly, beginning 200 days after flowering until harvest, totaling seven sampling dates. The data sets of each location were analyzed independently through a two-way analysis of variance (ANOVA) involving rootstocks in a split plot array in time (days) to allow for the assessment of the significance of the main effects, complemented by regression analysis. In general, the ripening of ‘Valencia’ orange fruits was influenced by the different ‘Trifoliata’ hybrid rootstocks. At the RA location, trees on IPEACS-256 and’ US-852’ citrandarins had the highest SS, and on ‘US-852’ citrandarin had the highest MI, reaching the MIim earlier than the other rootstocks. The highest CCI was achieved when trees were on IPEACS-256 citrandarin. At the SSA location, trees on ‘US-852’, IPEACS-256, and IPEACS-264 citrandarins had the highest SS, but on ‘US–852’ had the highest MI, reaching the earliest MIim among the rootstocks. The highest CCI was achieved when trees were on ‘US-852’ and IPEACS-256 citrandarins. In the SSJ location, there was no significant effect of the rootstocks on and of the variables of ‘Valencia’ orange fruit. This assessment can be useful in the planning of new orchards producing high-quality fruit with desirable features for the orange juice industry.

“…When grafted on 'Trifoliata' hybrid rootstocks, orange trees produce high-quality fruit with desirable attributes for the juice industry, such as high SS content and juice yield [20,23,[30][31][32][33]. 'Swingle' is the best-known citrumelo in Brazil and globally.…”

“…Other researchers reported that citrus scion grafted on Citrumelo and Rangpur lime had the same canopy volume (Gonzatto et al 2011;Bacar et al 2017). The use of Fortunella as rootstock caused tree size and canopy volume of citrus scion smaller than other rootstocks (Ono and Hirose 1987;Donadio et al 2019). However, the Fortunella is a subtropical citrus, adaptation within the tropical area such as in Indonesia is still to be examined.…”

Abstract. Yulianti F, Adiredjo AL, Soetopo L, Ashari S. 2020. Short Communication: Morphology and genetic characteristics of potential citrus rootstock in Indonesia. Biodiversitas 21: 5514-5520. Study on variability among the citrus rootstock genotypes is very important to classify and utilize citrus germplasm resources. The genetic variability would greatly assist the breeders in genotypes identification to develop database and maintain the germplasm repositories in Indonesia. It would also be helpful for stakeholders to choose the right rootstock. The aim of the study was to identify the morphology and genetic variability among three potential citrus rootstocks in Indonesia. Morphological and molecular techniques were used to characterize three citrus rootstocks potential in Indonesia. Characteristics of plant, leaves, flowers, fruits, seeds, and genomic DNA polymorphisms were used to characterize three potential citrus rootstocks (Japansche citroen (JC), Citrumelo and Kanci). Morphological characterizations were based on Descriptors for Citrus (IPGRI 1999). Genetic variabilities were conducted using seven specific markers for biotic and abiotic stresses (VP, CMA, PIP1a, PIP1b, PIP2, osmotin, and Y65). The important characters of citrus rootstock for growers were tree shape, tree growth habit, number of seed, seed polyembryony, and tolerance to biotic and abiotic stresses. JC has spheroid tree shape with spreading growth habit, while Citrumelo and Kanci have ellipsoid tree shape with erect growth habit. These characters may influence scion vigor and size. All of rootstocks observed have high number of seed and polyembryony. These rootstocks amplified PIPs and osmotin markers and could not amplify VP, CMA, and Y65 marker. These plants thought to have the characteristic of tolerance to drought stress with formation of aquaporin and osmotin but susceptible to salinity and Citrus tristeza virus.

“…Citrumelo is tolerant to Citrus Tristeza Virus (CTV) (Castle et al, 2000), nematodes, Phytophthora spp., CSD (Bové and Ayres, 2007) and cause the superior fruit quality of scion. The use of Fortunella as rootstock caused tree size and canopy volume of citrus scion smaller than other rootstock (Donadio et al, 2019). Unfortunately, there is still no study of the effect of rootstocks on the physiology of citrus plants in Indonesia.…”

Background: RGL mandarin is one of the important mandarin citrus varieties in Indonesia. The tolerance of RGL mandarin citrus to water deficit can be induced by the rootstock. This study aimed to characterize the physiological responses and transcriptional gene expression of RGL mandarin citrus grafted onto three rootstock genotypes during the dry and the rainy seasons.Methods: Three-years-old mandarin citrus trees cv. Rimau Gerga Lebong (RGL) grafted onto three citruses (JC, Cit and K) were planted at the experimental field of the ICISFRI. The experiment was conducted with a randomized block design and each scion-rootstock combination contained five replications. All of the physiological and relative gene expression parameters observed were conducted at the last of the dry season (September 2019) and the mid of the rainy season (January 2020). Water deficit was induced by no watering plants during the dry season.Result: The results of physiological responses and relative gene expression analyses showed that RGL-Cit combination had better than RGL-JC combination and RGL-JC combination had better than RGL-K combination. RGL-Cit combination showed less wilt than RGL-JC and RGL-K combinations. The RGL-Cit combination had the highest stomatal density, stomatal aperture, stomatal conductance and photosynthetic rate in the dry season. Different plant combinations showed different gene expressions. RGL-JC and RGL-K combinations were upregulated in almost all the primers related to drought responses tested in the dry season. RGL-Cit combination only upregulated the PIP1, PIP2 and ACS2 and unregulated the others in the dry season. Therefore, citrumelo seems to be a valuable type of rootstock.
