Abstract

A dwarf nectarine tree which is large for such type of tree, medium vigorous, spreading, open, vase-formed, and hardy; foliated with large, lanceolate, acutely pointed leaves having a crenate margin, medium length petiole, and alternate, reniform glands; blooms medium season from buds which are hardy and of medium size and length; the flowers being large and pink; and the tree being a regular and productive bearer of medium size, uniform, symmetrical, globose-oblong, early mid-season freestone fruit having yellow skin substantially overspread with red, and yellow flesh.

Description

CLASSIFICATION OF THE VARIETY

The present variety of nectarine tree is embraced by Class 41, Plants, of the U.S. Patent Office Manual of Classification.

BACKGROUND OF THE VARIETY

Over a substantial number of years I have engaged in an extensive and continuing plant breeding program at my experimental nursery and orchard located near Le Grand, Merced County, Calif.; one purpose of such program being to provide improved varieties of fruit trees. The present variety of nectarine tree resulted from my endeavors in the conduct of such plant breeding program.

ORIGIN OF THE VARIETY

The present variety of dwarf nectarine tree was originated by me as an open pollinated seedling of an unnamed dwarf nectarine tree; the variety, as so originated, having been grown under careful and continuing observation, and--upon evidencing desirable characteristics for commercial production--the variety was selected for asexual reproduction.

ASEXUAL REPRODUCTION OF THE VARIETY

Subsequent to origination and selection by me of the present variety of dwarf nectarine tree, I asexually reproduced it by top-working on orchard trees, and--in maturity--such reproduction ran true to the original tree in all respects.

SUMMARY OF THE VARIETY

The present variety of dwarf nectarine tree is large for such type of tree, medium vigorous, spreading, open, vase-formed, and hardy; foliated with large, lanceolate, acutely pointed leaves having a crenate margin, medium length petiole, and alternate, reniform glands; blooms medium season from buds which are hardy and of medium size and length; the flowers being large and pink; and the tree being a regular and productive bearer of medium size, uniform, symmetrical, globose-oblong, early mid-season, freestone fruit having yellow skin substantially overspread with red, and yellow flesh.

The present variety of dwarf nectarine tree, while large for the type, is less than one-half the height of conventional or full-size nectarine trees, bears fruit quite heavily, and produces satisfactorily under a wide range of growing conditions.

BRIEF DESCRIPTION OF THE DRAWING

The drawing is an illustration, by photographic reproduction in color, of a twig with leaves, separate fruit, and a separate stone; one fruit being partially cut away to expose the flesh.
