Narrative
80E-1 is a wild type of P. communis with a curious history and some valuable traits. In the 1920's the Horticulture Dept of the University of Illinois received a shipment of apple seeds from the St. Petersburg Botanic Garden of the USSR. Seedlings from these seeds were planted at the Horticulture Farm. In the early 1950's while a graduate student, Barrett noted a few pear seedlings growing among these apple seedlings. Barrett selected this seedling because of its good fireblight resistance and right angle limbs. During the 1956 bloom with temperatures around 22-23 degrees F, Barrett observed none of the blossoms were frozen, although every pear in the collection of about 200 flowering at the time had unfrozen blossoms or fruit that year. The fruit is poor quality, small and worthless per se, but the above mentioned traits should make it worth keeping. -- Herb Barrett, January 1995 The fruit are small (33 x 26 mm), round, regular contour, medium length stem, moderately russeted, but appearance was only fair, with coarse texture, gritty flesh and moderately poor flavor, probably somewhat acidic or astringent. It was discarded from the USDA breeding program. -- R. Bell, September 2012
