BRIEF DESCRIPTION OF THE VARIETY

The new variety of pear tree ‘PremP109’ was created in the course of a planned breeding program carried out at Hawkes Bay, New Zealand. ‘PremP109’ originated as a result of a controlled cross of ‘P125R74T032’ (seed parent, not patented) and ‘P125R95T002’ (pollen parent, not patented). ‘PremP109’ was selected as a single plant from among a population of seedlings derived from the parents, and was selected for its attractive red color and unique appearance, superb texture and flavor, and long shelf life. PremP109 has a thinner, less bitter skin, no flesh astringency, more flavor, is larger and has no russet on the cheek compared to the parent varieties. Compared to other known Asian pear cultivars, PremP109 has a lemon color with an orange blush rather than a green color. It's larger and has more flavor with higher sugar than other Asian pear varieties. 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.
