Nectarine tree denominated ‘Summer Lion IV’

Abstract

A new and distinct variety of nectarine tree which is somewhat similar to the ‘Summer Lion II’ nectarine tree but from which it is distinguished by producing fruit which are mature for harvesting and shipment approximately seven (7) days after ‘Summer Lion II’ fruit in the San Joaquin Valley of central California and wherein the fruit is of high quality and good flavor with dark red coloration over most of the fruit surface.

Description

Latin name of the genus and species of the plant claimed: Prunus persica var. nectarine.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of nectarine tree, Prunus persica var nectarina, which will hereinafter be denominated varietally as the ‘Summer Lion IV’ nectarine tree, and, more particularly, to a nectarine tree which produces fruit which is mature for commercial harvesting and shipment approximately July 15^th through July 30^th, or about one week after ‘Summer Lion II’ nectarine tree (U.S. Plant Pat. No. 6,544), in the San Joaquin Valley of central California. The subject new variety hereof has, in summary, fruit which is large in size with a moderately red and dark red blush color and a yellow-orange flesh color.

The discovery and development of new plant varieties is a daunting task. Nonetheless, these efforts take place in many areas of the world. The motivation for such efforts is both to assist mankind in the improvement of the varieties in a multitude of respects, as well as to achieve rewarding commercialization thereof. These activities have been particularly focused in the San Joaquin Valley of central California where growing conditions are quite favorable. As a consequence of these and other factors, a multitude of individuals, business entities, research institutions, universities and others have engaged in such research and development. The process is difficult, time consuming and expensive. As a consequence, these efforts are directed to the recovery of costs and, more typically, significant financial reward through commercialization. However, it is very difficult to select varieties which may achieve commercial success.

The new variety of nectarine tree of the present invention is believed by the inventors to be a promising candidate in a number of significant respects, as will hereinafter be set forth in greater detail.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of nectarine tree hereof was discovered by the inventors in their orchard located near Selma in the San Joaquin Valley of central California. The inventors discovered the variety as a newly found seedling in the spring of 2001, the result of cross pollination between the ‘June Lion’ nectarine tree (U.S. Plant Pat. No. 13,792) and ‘Summer Lion II’ nectarine tree (U.S. Plant Pat. No. 6,544). In the spring of 2001 the new variety of nectarine tree had budwood selected from the subject nectarine tree which was then grafted on Nemaguard rootstock planted in their test block in a ‘Summer Lion II’ nectarine orchard. The inventors have observed the asexually reproduced growth and fruit of the new variety and have found that, in all respects, the resulting progeny are identical to that of the original tree of the new variety.

SUMMARY OF THE NEW VARIETY

The nectarine tree of the new variety is characterized by producing a fruit which is ripe for commercial harvesting and shipment approximately July 15^th through July 30^th in the San Joaquin Valley of central California. This is about seven (7) days later than ‘Summer Lion II’ nectarine tree (U.S. Plant Pat. No. 6,544). The new variety of the present invention is distinguished from its parent trees primarily in the date of ripening, by being more intensely colored and by having slightly smaller fruit. The new variety of the present invention is most closely similar to the ‘Summer Lion II’ nectarine tree (U.S. Plant Pat. No. 6,544), but is distinguished therefrom in the aforementioned respects.
