Abstract
‘JR13’ is a new and distinct grapefruit tree notable for its attractive, seedless fruit.
Description
Genus and species: Citrus×paradisi.
Variety denomination: ‘JR13’.
The new grapefruit variety ‘JR13’ originated in Malelane, South Africa in 2005 as an induced mutation of ‘FE1’ grapefruit (not patented). Mutation was induced through exposure of budwood to gamma radiation. Radiated budwood was budded to ‘Carrizo’ citrange rootstock and the scion selections monitored for characteristics of low seed content. The selection with the lowest seed count, highest fruit yield, and best internal fruit quality was selected for planting and further observation at Malelane, South Africa and named ‘JR13’. ‘JR13’ has been observed over successive generations and has been found to retain its distinguishing characteristics.
‘JR13’ is a new and distinct grapefruit tree notable primarily for its attractive, seedless fruit. Table 1 shows a comparison of ‘JR13’ to parent ‘FE1’ and ‘Marsh’ (not patented) grapefruit varieties.
TABLE 1 |
Comparison of ‘JR13’ to Known Varieties |
Characteristic | ‘JR13’ | ‘FE1’ | ‘Marsh’ |
Seed quantity | Seedless | Some seeds | Some seeds |
Maturity | Mid- to late-season | Mid-season | Early season |
Fruit shape | Oval to globose | Globose | Globose |
Because lighting conditions can affect the colors shown in photographic illustrations, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from the illustrations alone.
The following detailed botanical description is based on observations of trees and fruit of ‘JR13’, budded to ‘Carrizo’ citrange rootstock and planted in 2010. Observations were recorded and photographs taken during the 2011 and 2014 growing seasons at Malelane, South Africa. It should be understood that 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 trees of the new variety. The measurements of any individual tree, or any group of trees, of the new variety may vary from the stated average. Color references are to The Royal Horticultural Society Colour Chart
