Abstract
A pear tree which is a mutation of the standard Anjou variety, characterized by an overall bright-red fruit skin color and by a slow respiration rate and low ethylene production of the fruits during storage. The slower fruit ripening rate which results from these storage characteristics imparts to the fruit a longer storage and shelf life when compared with fruits harvested from the standard Anjou parent and those harvested from another patented Red Anjou sport variety.

A new and distinct variety of pear tree substantially as illustrated and described herein, characterized particularly by the overall bright-red skin color of the fruit, the slower respiration rate and lower ethylene production of the stored fruits, its slower fruit-ripening rates and longer storage and shelf-life than in the parent Anjou variety of pear tree, and its fruit having an oblong-obovate-pyriform shape, many conspicuous small russet fruit dots, a thin skin, red color prior to harvest, sweet spicy flesh and slightly granular, firm, tender, buttery, and juicy texture, and its flowers having a very light pink coloration with streaks of darker pink.
