BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of pear tree named ‘ANP-0118’. My new tree resulted from a planned hybridization program and is a selection from crossing ‘Butirra Precoce Morettini’ (Unpatented) as the seed parent with ‘Corella’ (Unpatented) as the pollen parent. The resulting tree was selected when growing in a cultivated area in Goulburn Valley, Australia. The cross was made in 1995 at Stoneville, Western Australia and the population of 434 seedlings established at Tatura, Victoria, Australia. The seedling tree of the ‘ANP-0181’ variety was selected in 2001 and planted into a replicated trial on ‘D6’ (not patented) rootstock and ‘Quince A’ (not patented) rootstock with ‘Beurre Hardy’ (not patented) pear as an interstock in 2003. Additional trees of the seedling selection were planted at Australian Pome Fruit Improvement Program (APFIP) sites in Western Australia, South Australia and Victoria in the same year for regional evaluation. Further asexual propagation by budding and grafting of trial trees in 2009 and 2012 for large scale evaluation trials at Tatura on ‘BP1’ rootstock (U.S. Plant Pat. No. 10,231) showed that the foregoing characteristics come true to form, are firmly fixed, and are established and transmitted through succeeding propagations.

BRIEF SUMMARY OF THE INVENTION

The ‘ANP-0118’ variety is distinguished from other pear varieties due to the following unique combination of characteristics: Fruit are tree ripened with a fine, crisp texture around the harvest period of ‘Williams' Bon Chrétien’ pear (not patented). The flesh is less juicy than varieties such as ‘Doyenne du Comice’ and ‘Williams' Bon Chrétien’. The fruit are pyriform with a bright red blush over a light green to yellow skin color dependent upon the harvest period. Unlike blushed varieties such as Forelle (not patented) it does not display a ‘speckled’ red lenticel overcolour.

The new variety was determined to be distinct from the parent varieties ‘Butirra Precoce Morettini’ and ‘Corella’ by the following characteristics: The time of beginning of flowering for ANP-0118 is about a week later than ‘Corella’ whilst its maturity for consumption is before both ‘Corella’ and ‘Butirra Precoce Morettini’. ‘ANP-0181’ has a distinct fine, crisp flesh that can be eaten directly off the tree whilst both ‘Butirra Precoce Morettini’ and ‘Corella’ have typical European pear flesh texture that is hard and dense and requires maturation under cool storage to be consumed.

The following detailed description concerns the original tree, selected on January 2001, and progeny first asexually propagated in 2003. The original tree and progeny have been observed growing in a cultivated area in Goulburn Valley, Australia.

Certain characteristics of this variety may change with changing environmental conditions (such as photoperiod, temperature, moisture, soil conditions, nutrient availability, or other factors). For example, leaf colors may be brighter green if the trees are grown in soil with greater nitrogen concentrations, and may be more yellow when grown in soil containing lesser amounts of nitrogen. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations (hue/value/chroma) are made with reference to The Royal Horticultural Society Colour Chart (R.H.S.) version 2 published in 1966.
