Abstract
‘7ELS1’ is a new and distinct lemon tree notable for its high quality fruit with very few or no seeds.
Description
Genus and species: Citrus limon.
Variety denomination: ‘7ELS1’.
The new lemon variety ‘7ELS1’ originated as an induced mutation of ‘Eureka’ lemon (not patented). Varying degrees of Gamma irradiation from a Gammacell 200 (60C) source was applied to bud sticks of ‘Eureka’ in 1996 at St. Lucia, Queensland, Australia. The 1200 treated bud sticks were budded onto ‘Carrizo’ rootstock during June 1996, and the 1034 trees that survived were field planted at Emerald, Queensland, Australia during Autumn of 1997. As trees commenced fruiting, fruit from different branches on each tree were cut and inspected for seed numbers. This procedure was carried out during July of 1998, 1999 and 2000. The selection now known as ‘7ELS1’ was identified as showing consistently lower seed numbers than the parent variety with no apparent reduction in fruit size. ‘7ELS1’ also showed good fruit quality and good internal color in all three seasons. Budwood was taken from the original selection and budded to ‘Benton’ rootstock to establish mother trees. A further generation of trees was established by taking budwood from these mother trees and establishing granddaughter trees (again budded to ‘Benton’ rootstock), which were planted in 2003. All generations have consistently shown few or no seeds in each season.
‘7ELS1’ is a new and distinct lemon tree notable for its fruit, which produces consistently low numbers of seeds. Table 1 shows a comparison of ‘7ELS1’ lemon to ‘Eureka’ and other similar (unpatented) varieties.

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 ‘7ELS1’, budded to ‘Benton’ rootstock (not patented) and planted in 2003. Observations were recorded and photographs taken during the 2006 and 2011 growing seasons at Munduberra, Queensland, Australia. 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 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 (5th Ed., 2007).
