Abstract

A new and distinct variety of peach tree which is somewhat similar to the ‘Island King’ peach tree (U.S. Plant Pat. No. 9,199) from which it is a sport, but from which it is distinguished by producing a later ripening fruit which are mature approximately ten to fourteen days after the fruit produced by the ‘Island King’ peach tree.

Description

BACKGROUND OF THE NEW VARIETY
The present invention refers to a new variety of peach tree which will hereinafter be denominated as the ‘Island Prince’ peach tree which produces clingstone fruit which are mature for commercial harvesting and shipment approximately May 8-10 in a normal growing year in the San Joaquin Valley of Central California as an early 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. This new invention meets all of the aforementioned criteria and therefore is of commercial appeal to the consumer.
ORGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The present variety of peach tree was discovered by the inventor in his 4-acre orchard of ‘Island King’ peach trees (U.S. Plant Pat. No. 9,199) which is located near Kingsburg, Calif. The inventor discovered it as a sport of the ‘Island King’ peach tree in 1997. The new variety was first asexually reproduced by the inventor in 1997 by bud grafting two trees on Nemaguard Rootstock in the orchard of orgin. The asexually reproduced trees first bore fruit of the new variety in May 1998. The inventor carefully compared the asexually reproduced trees with the parent sport, including the fruit thereof and the parent as well as the progeny is in all respects identical.
SUMMARY OF THE NEW VARIETY
The ‘Island Prince’ peach is characterized by producing an extra large clingstone fruit which has good red blush coloration and is ripe for commercial harvesting and shipment approximately May 8 to May 10 in the San Joaquin Valley of Central California. The new variety is most similar to ‘Island King’ peach tree (U.S. Plant Pat. No. 9,199) from which it is a sport but from which is distinguishable in that it ripens ten to fourteen days later than the fruit of ‘Island King’ peach tree and in that the fruit is about one-third again larger in size than that of the ‘Island King’ peach tree. The fruit of this new variety possesses a very good flavor as well as aroma which is greatly acceptable for an early ripening variety.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph showing fruit and foliage of the new variety. The view on the left side of the photograph displays a fruit cut in half showing the pit and the flesh on the upper half and the pit well and the flesh on the bottom half. In the center is the fruit showing the distal end and the suture, while on the upper right is a fruit showing a side view with the cheek surface. The fruit on the bottom right shows the stem end of the fruit. The top of the photograph shows the foliage typical of this variety of peach tree.
