Abstract
‘Ruby SL’ is a new and distinct orange tree notable primarily for its intensely colored seedless fruit.
Description
Genus and species: Citrus sinensis.
Variety denomination: ‘Ruby SL’.
The new orange tree ‘Ruby SL’ resulted from an irradiation-induced limb mutation of ‘Ruby Valencia’ orange (not patented). Budwood from the irradiated limb was budded onto rootstock to produce second-generation trees, which were planted in 2013. ‘Ruby SL’ orange tree has been observed and found to retain its distinguishing characteristics through successive asexually propagated generations. Development, selection and asexual propagation of ‘Ruby SL’ were carried out at Nelspruit, Mpumalanga, South Africa.
‘Ruby SL’ is a new and distinct orange tree notable primarily for its intensely colored seedless fruit. The fruit size is notably larger than that of its parent ‘Ruby Valencia’. Other noticeable differences from the ‘Ruby Valencia’ include: The ‘Ruby SL’ tree is not as precocious and produces a smaller yield as compared to ‘Ruby Valencia’. ‘Ruby SL’ is expected to mature earlier than the ‘Ruby Valencia’ based on trial observations. A comparison of ‘Ruby SL’ to related and similar varieties is set forth in Table 1.

The attached photographs, taken in 2019 at Visalia, Calif., depict ‘Ruby SL’ fruit and four-year-old ‘Ruby SL’ trees. Actual colors will vary with lighting conditions; color characteristics of ‘Ruby SL’ orange should therefore be determined with reference to the observations described herein, rather than from these illustrations alone.
The following detailed botanical description is based on observations made in 2019 at Visalia, Calif., of four-year-old ‘Ruby SL’ trees on ‘Rough Lemon’ rootstock (not patented). The characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average. Colors are described with reference to The Royal Horticultural Society Colour Chart (fifth edition).
