Definitions

  • the new variety of pear tree ‘PremP52’ was created in the course of a planned breeding program carried out at The New Zealand Institute for Plant and Food Research, Hawkes Bay, New Zealand. ‘PremP52’ originated as a result of a controlled cross of ‘T002’ (not patented) and ‘Prem1P’ (U.S. Plant Pat. No. 17,624). ‘PremP52’ was selected as a single plant from among a population of seedlings derived from the parents, and was selected for its fruit size, flavor and appearance. Asexual propagation by budding was first carried out in Nelson, New Zealand. The variety has since been observed over a number of asexually propagated generations, and has been found to remain true to type.

Abstract

A new and distinct pear tree named ‘PremP52’ is disclosed. The new variety is notable for its attractive yellow fruit with light red blush, long shelf life and crisp, firm texture.

Description

Latin name: Pyrus communis.
Variety denomination: ‘PremP52’.
BACKGROUND OF THE VARIETY
The new variety of pear tree ‘PremP52’ was created in the course of a planned breeding program carried out at The New Zealand Institute for Plant and Food Research, Hawkes Bay, New Zealand. ‘PremP52’ originated as a result of a controlled cross of ‘T002’ (not patented) and ‘Prem1P’ (U.S. Plant Pat. No. 17,624). ‘PremP52’ was selected as a single plant from among a population of seedlings derived from the parents, and was selected for its fruit size, flavor and appearance. Asexual propagation by budding was first carried out in Nelson, New Zealand. The variety has since been observed over a number of asexually propagated generations, and has been found to remain true to type.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
FIG. 1 shows the fruit and leaves of a ‘PremP52’ pear tree; and,
FIG. 2 shows fruit from a ‘PremP52’ pear tree.
 DETAILED BOTANICAL DESCRIPTION OF THE VARIETY
