Peach tree named ‘FA 42’
A new peach variety, Prunus persica, (hereinafter referred to as ‘FA 42 peach’) which was developed in 1981 by Annette and Randy Bjorge in a breeding program at Fruit Acres Farms in Coloma, Mich., having the following combination of unique and desirable features: 1. A substantially large, round fruit with an attractive bright red blush covering 75 to 80% of the fruit at maturity. 2. A fruit maturing late in the season, 7 days after ‘Fayette’ or 45 days after ‘Redhaven’. 3. A fruit with excellent storage and shipping qualities. 4. A fruit with flesh that does not brown when cut.

A new and distinct variety of peach tree originating as a cross of ‘Autumnglo’ and ‘Fayette’ varieties of Prunus persica hereinafter referred to as ‘FA 42’ peach. This variety is unique from its parents because the fruit is both highly colored and round and the tree has good bud and wood hardiness. ‘FA 42’ ripens later than both parents, 6 days after ‘Autumnglo’ and 7 days after ‘Fayette’ with large, 75 to 80% blushed red fruit.SUMMARY OF THE INVENTION
This new and distinct variety of peach tree was developed in a breeding program in 1981 by Annette and Randy Bjorge of Coloma, Mich. It resulted as a cross of ‘Autumnglo’ and ‘Fayette’, both unpatented peach cultivars. The new variety was noticed because it ripened very late in the season with a high color factor and large size.
The new variety was budded on Bailey peach seedling in the summer of 1988 and planted for further testing on Fruit Acres Farms, Coloma, Mich. In the summer of 1992, ‘FA 42’ was budded on Halford peach seedling. In the spring of 1993, these trees were sent to the following cooperating testers under testing agreements: Rutgers Snyder Research Farm, Pittstown, N.J.; Lee Spencer, Boyertown, Pa.; Adams County Nursery, Aspers, Pa.; Kenneth Kauffman, Bird-in-Hand, Pa.; Thomas Benton, Chester, N.J.; Clemson University, Clemson, S.C.; Arnold Klug, Berrien Center, Mich.; North Carolina State University, Raleigh, N.C.; Rutgers Cooperative Extension, Clayton, N.J.; SW Michigan Research & Extension Center, Benton Harbor, Mich.; and The University Of Arkansas, Clarksville, Ark.
The reports from the cooperating testers showed that the new variety remained true to name and showed considerable commercial promise as a peach for the late harvest season.COMPARISON TO PRIOR ART
‘FA 42’ ripens vary late in the commercial peach season with a large sized fruit and a very high degree of red skin color. This contrasts to ‘Fayette’, (an unpatented selection) which ripens 13 days earlier and is much less highly colored. ‘FA 42’ ripens 6 days after ‘Autumnglo’ (an unpatented selection) and is more highly colored with a lighter degree of pubescence. The new variety ripens 6 days after ‘Encore’ (U.S. Plant Pat. No. 4,572) and has a much higher degree of red skin color. ‘FA 42’ ripens 15 days after ‘PF 27A’ (U.S. Plant Pat. No. 9,939). ‘FA 42’ ripens 2 days after ‘Laurol’ (U.S. Plant Pat. No. 8,558) and has a bright red skin color contrasting with the orange-red of ‘Laurol’. ‘FA 42’ also has a much greater degree of bud and wood hardiness than ‘Laurol’.BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographs show typical specimens of the new variety as depicted in color as nearly true as is reasonably possible in color illustrations of this character. These specimens were obtained at Coloma, Berrien County, Mich.
FIG. 1 illustrates the coloration of the fruit of the new variety in comparison with the coloration of ‘Fayette’ and ‘Encore’ (U.S. Plant Pat. No. 4,572). ‘Encore’, picked on September 17, is pictured on the top; ‘FA 42’ picked on September 24, is pictured in the middle segment; ‘Fayette’, picked on September 11, is shown in the bottom section. All three varieties were grown on the same farm in Coloma, Berrien County, Mich.
