BRIEF DESCRIPTION OF THE PHOTOGRAPHS

FIG. 1 shows the fruit of a ‘PremP027’ pear tree at harvest time.

BRIEF DESCRIPTION OF THE VARIETY

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’.

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.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY
