Campas (PI 541705; PI 541706). -Originated in St. Petersburg, Florida, on the farm of Martin Campas. Introduced in 1935 by Stanley Johnston, Michigan Agriculture Experiment Station., South Haven, Michigan. Parentage unknown; discovered in 1923 by the U.S. Dept. of Agriculture, which propagated and distributed trees for trial purposes to many experiment stations; it proved of sufficient value for canning in comparison with Kieffer at the Michigan Station to warrant its introduction and naming. Fruit: size medium; skin yellow, somewhat russeted; flesh with fewer grit cells, whiter, and softer than Kieffer, which it resembles; ripens late. Tree: high degree resistance to fire blight. -- Brooks and Olmo Register of Fruit and Nut Varieties.Campas No. 1 - Fruit somewhat larger than Kieffer in size and inclined to be more oblong in form. Closely resembles Kieffer in color and finish. No improvement over Kieffer in dessert quality. Earlier than Kieffer in season and fruit breaks down badly after a period in cold storage. Tree very vigorous, highly productive, upright grower but bends down with weight of fruit, not fully evaluated as to blight resistance. -- H. Hartman 1957.
