Abstract

A new and distinct variety of apple tree ‘Malus Pumila Mil’ named ‘Emmons’ and which is characterized as to novelty by a uniqueness of shape, color, flavor and texture of the fruit, and a date of maturity for commercial harvesting and shipment of about September 29^th under the ecological conditions prevailing in Central Washington.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of apple tree ‘Malus Pumila Mil’ and which has been denominated varietally as ‘Emmons’ and more particularly to an apple tree which bears a distinctively colored round apple which has a dense sweet flesh, and which further is noteworthy because it retains its firmness after harvesting and can be stored for long periods of time with little deterioration in the overall quality of the fruit.

ORIGIN AND ASEXUAL REPRODUCTION

It has long been recognized that a very important factor contributing to the success of any variety of apple tree bearing fruit for the fresh market is its ability to produce an attractively colored fruit, which has a distinctive noteworthy flavor, and which further has good handling and storage characteristics. The new variety ‘Emmons’ is noteworthy as noted above, in producing an attractively and distinctively colored fruit having a distinctive pink stripe over a cream-yellow background and which further has a distinctive taste, dense flesh and a sweetness with a hint of tartness. The new variety is firm at harvest and can be handled with little skin or flesh damage. The new variety ‘Emmons’ is harvested during the same season where other well-known varieties such as the Red Delicious (unpatented) are harvested under the ecological conditions prevailing in the Columbia Basin of Washington State. However, the present variety is noteworthy in producing a highly desirable dessert-type apple having noteworthy characteristics which distinguish it from other varieties which it is mostly similar to.

The new variety of apple tree ‘Malus Pumila Mil’ was discovered as a chance seedling growing within the cultivated area of the Applicant's orchard which is located near Gleed, Wash. The inventor discovered the chance seedling following the purchase of the same orchard in 1978. The orchard contained a variety of different apple trees including Golden Delicious (unpatented), and several different cultivars of Red Delicious apple trees all of which are unpatented. The inventor, with the intent that he would remove and replant trees in the future, deferred maintenance for several years allowing the chance seedling to develop. Subsequently, the inventor noted the chance seedlings unique characteristics and marked the variety for subsequent observation. In 1993, the inventor removed wood from the original tree and bench grafted it onto ‘M-7’ rootstock (unpatented). This original asexual reproduction in Gleed, Wash., produced 20 trees which were then planted in a nearby orchard. These test trees have since produced fruit and the inventor has confirmed that this first asexual propagation resulted in apple trees being produced which possess the same distinctive characteristics as the original chance seedling. Additional asexual reproductions have taken place in the years 1997-2004. These subsequent asexual reproductions have also confirmed the unique characteristics of the new apple tree.

The present variety ‘Emmons’ is most similar in its date of harvesting to the Red Delicious apple tree named ‘Bisbee’ (U.S. Plant Pat. No. 1,565) when grown under the same ecological conditions. In relative comparison to the ‘Bisbee’ apple tree, the ‘Emmons’ apple tree produces fruit which is round in relative comparison to the elongated Red Delicious apple shape that is quite familar to those who are skilled in the art. Still further, the ‘Emmons’ apple tree produces a fruit which has a pink stripe over a cream-yellow background that is unlike the coloration of any Red Delicious variety which is known. Still further, the growing characteristics of typical Red Delicious apple trees, especially the ‘Bisbee’ cultivar is typically more upright, then spreading, and its growth is only moderately vigorous. In relative comparison, the ‘Emmons’ apple tree is more spreading in form than most Red Delicious cultivars, and this growth pattern appears more vigorous. Still further, the ‘Emmons’ apple tree produces a fruit that has a unique and pleasing taste which is distinctly different from the fruit produced by known Red Delicious cultivars.

SUMMARY OF THE VARIETY

The ‘Emmons’ apple tree is characterized principally by novelty by producing a unique, attractively colored round-shaped apple which is ripe for harvesting and shipment about September 29^th under the conditions prevailing in the Columbia Basin of central Washington State.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings are color photographs of the present variety. These photographs depict whole fruit, fruit dissected in both the axial plane, as well as the plane transverse to the axial plane, typical leaves of the variety, and the branching habit of the same variety. Still further, a photograph is provided showing the present variety of fruit along side the fruit produced by the variety which is most closely similar to the date of harvesting of this new variety. The external coloration of the fruit as shown in these photographs is sufficiently matured for harvesting and shipment. These colors are as nearly true as reasonably possible and a color representation of this type. Due to chemical development, processing and printing, the leaves and fruit depicted in these photographs may or may not be accurate when compared to the actual specimen. For this reason, future color references should be made to the color plates (Royal Horticulture Society), and descriptions provided hereinafter. Occasionally, common color names will also be used.

FIG. 1 shows the fruiting habit of the present variety. The apples as seen in this photograph are sufficiently matured for harvesting and shipment.

FIG. 2 shows both the dorsal and ventral coloration of typical leaves taken from the present variety.

FIG. 3 shows an apple of the present variety dissected in the axial plane in order to show the flesh characteristics thereof.

FIG. 4 is a typical fruit dissected transverse to the axial plane and showing the flesh characteristics and pips thereof.
