Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) FIG. 1 shows the fruit of a PremP027 pear tree at harvest time.

BRIEF DESCRIPTION OF THE VARIETY

(2) The new variety of pear tree PremP027 was created in the course of a planned breeding program carried out at Motueka, New Zealand. PremP027 originated as a result of a controlled cross of Max Red Bartlett (seed parent, U.S. Plant Pat. No. 741) and Snowflake (pollen parent, not patented) in 1989. PremP027 was selected in 1996 as a single plant from among a population of seedlings derived from the parents, and was selected for its quality of fruit. It is distinguished from its parents by its shape and color. Max Red Bartlett fruit is pyriform in shape with high coverage of red skin color compared to PremP027 which has no red skin color. PremP027 is almost round with slight tapering at the stem and calyx end. Fruit of PremP027 ripens 7-10 days later than Max Red Bartlett. Fruit of PremP027 has less prominent lenticels than Snowflake and ripens approximately 14-21 days earlier. PremP027 is also distinguishable from other known varieties, such as Nijisseiki (U.S. Plant Pat. No. 8,529). Nijisseiki has more round fruit than PremP027 and ripens approximately 7-10 days earlier. PremP027 is distinguishable from related variety PremP003 (U.S. Ser. No. 14/544,403, pending) by its more upright growth habit and early harvest maturity. PremP027 is ready for harvest about three weeks earlier than PremP003.

(3) Asexual propagation by budding was first carried out in Motueka and Havelock North, New Zealand. The variety has since been observed over a number of asexually propagated generations, and has been found to remain true to type.
