Tangor tree named ‘Leanri’

Abstract

‘Leanri’ is a new and distinct tangor tree notable for its early maturing, medium to large nearly seedless fruit.

Description

Genus and species: Citrus reticulata×Citrus paradisi.

Variety denomination: ‘Leanri’.

BACKGROUND AND SUMMARY OF THE VARIETY

The new tangor variety ‘Leanri’ originated as a branch mutation of a ‘Clementine×Murcott’ tree (not patented), and was discovered by the inventors in 2001 in a commercial orchard at Malalane, Mpumalanga, South Africa. Propagative material was taken from the branch mutation and asexually reproduced by budding at Malalane, Mpumalanga, South Africa in 2008. Plants produced through asexual reproduction were observed to determine whether the desired characteristics of the mutation would carry through to asexually propagated progeny. It has been found that the tree and fruit of the new variety are reproduced true to type through asexual propagation and remain stable through successive asexually propagated generations.

‘Leanri’ is a new and distinct tangor tree notable for its early maturing, medium to large nearly seedless fruit. ‘Leanri’ is distinguished from similar varieties ‘Murcott’ and ‘Clementine×Murcott’, as set forth in the table below:

DETAILED BOTANICAL DESCRIPTION

The following detailed botanical description is based on observations of five-year-old trees and fruit of ‘Leanri’ planted in 2008 and grown on ‘Carrizo citrange’ rootstock (not patented). Observations were recorded and photographs were obtained during the 2013 growing season, at Malalane, Mpumalanga, 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 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 (2007).
