Description

ORIGIN OF THE VARIETY

The new and distinct variety of nectarine tree was originated by us in the experimental orchard located near Modesto, Calif., as a first generation seedling of a cross between a selected seedling with the field identification number of 37G890 and May Glo Nectarine (U.S. Plant Pat. No. 5,245). The female parent 37G890 originated from an open pollinated seedling of Ruby Gold Nectarine (U.S. Plant Pat. No. 3,101).

ASEXUAL REPRODUCTION OF THE VARIETY

The present variety was asexually reproduced by budding, as performed by us in the experimental orchard located near Modesto, Calif., and shows that said characteristics run true to the original tree and are established and transmitted through succeeding propagations.

SUMMARY OF THE VARIETY

The herein claimed new and distinct variety of nectarine tree is of large size, vigorous upright growth and a regular and productive bearer of medium size, firm, yellow flesh, early maturing clingstone fruit, having yellow skin substantially overspread with an attractive red color. The tree is further characterized by having a low winter chilling requirement of approximately 200 hours and being a regular and productive bearer in areas with warm winter temperatures such as Palm Desert, Calif.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show typical foliage and fruit of the present nectarine variety, with illustrations of the upper and lower surface of the foliage, an exterior view of the fruit and a fruit divided in its suture plane to reveal flesh coloration and showing a stone remaining in place. The photographic illustrations were taken shortly after being picked at maturity (firm ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.
