Abstract:
A new and distinct variety of peach tree which is distinguished by producing fruit having a freestone rather than a clingstone, with the fruit ripening for harvest approximately September 7-21 in a normal year.

Description:
BACKGROUND OF THE NEW VARIETY 
     The present invention refers to a new variety of peach tree which will hereinafter be denominated as the ‘MC 1936’ which produces freestone fruit which are mature for commercial harvesting and shipment approximately September 7-21 in a normal growing year in the San Joaquin Valley of Central California as a firm, late, fresh market peach with a good red blush coloration. 
     In the development of new commercial varieties of fruit specific characteristics places a premium on those varieties, which are early or late maturing, in the growing season. However, many such varieties have small size, lack of flavor, or coloration. In some instances there are other undesirable characteristics that decrease the commercial success. In order for a fruit to be a commercial success it must possess those characteristics of good size, good color, and good flavor. At the same time the date of maturity must be separate or different than other similar fruit. The fruit of the present variety also tends to retain its firmness longer than other peaches. This new variety meets all of the aforementioned criteria and therefore is of commercial appeal to the consumer. 
     ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY 
     A whole plant of the present variety of peach tree was discovered by the inventor in a grove of ‘Fayette’ peach trees (unpatented) located near Sanger, Calif. The inventor discovered it as a new tree in the year 2006 and observed it for eight years. The new variety was asexually reproduced in 2013 at Sanger, Calif. by bud grafting eight trees onto ‘Nemaguard’ (unpatented) rootstock in a nearby orchard. These eight trees first produced fruit in 2016. The inventor has carefully examined the asexually reproduced trees which appear to be identical to the parent. 
     SUMMARY OF THE NEW VARIETY 
     The subject ‘MC 1936’ variety is characterized by producing a large, firm freestone fruit which has good red blush coloration and is ripe for commercial harvesting and shipment approximately the second and third weeks of September in the San Joaquin Valley of Central California. The new variety is similar to ‘Calara’ (U.S. Plant Pat. No. 15,496), but from which is distinguishable in that the fruit is similar in size and appearance, has a freestone rather than a clingstone, and ripens after the end of the harvesting period of ‘Autumn Flame’ (U.S. Plant Pat. No. 9,438) and overlaps with the beginning of the harvesting period of ‘Calara’. The fruit of this new variety is firm, and possesses a very good flavor as well as an aroma that is greatly acceptable for a late ripening variety.
