@scottfsmith highly recommends doctor desportes because of its higher disease resistance. I’ve grown it here now in Kansas a couple of years with no signs of pest or disease. It has not flowered yet. Doctor desportes has a flavor somewhat like Beurre Bosc. The word Beurre
— translated from French means butter. Beurre Bosc is highly disease susceptible. Beurre is used to describe texture and flavor as buttery and like the word melting that is highly desirable. If you see beurre in the front you can bet its high quality pear! Thats why i want the following pears

As an example Beurre Alexandre Lucas has the description
“Originated as a chance seedling in the Department of Loire et Cher, France, 1866. Fruit resembles that of Buerre d’Anjou in size and form. Skin smooth, quite free of blemish, green-yellow with green dots, quite attractive. Flesh white, medium fine, buttery, juicy. Sweet with pleasing flavor, equal or superior to Buerre d’Anjou in dessert quality. Apparently keeps as long as Anjou in cold storage, ripens easily and retains it’s quality for some time afterwards. Somewhat softer than Anjou in texture and more susceptible to pressure bruises. Tree moderately vigorous, clean, and productive. Semi-dwarf on quince. Moderately susceptible to blight. – H. Hartman, Oregon Agricultural Experiment Station, 1957.” - https://www.ars-grin.gov/cor/catalogs/pyrcult.html
