Abstract

A new and distinctive variety of Malus domestica apple from a controlled cross of Huaguan x Honeycrisp that is distinctly different from its parents.

Description

Description

Latin name: Malus domestica.

Varietal denomination: ‘Regal D5-100’.

BACKGROUND

The present invention relates to a new, novel, and distinct variety of apple tree, and which has been denominated varietally as ‘Regal D5-100,’ and more specifically, to a novel apple tree with an upright growth habit with moderate vigor that may be pollinated from any other diploid apple of a mid-season bloom. The novel apple tree also produces fruit that are medium in size and that have streaked bi-color, that are slightly lopsided, and that exhibit four months of common storage life.

ORIGIN AND ASEXUAL REPRODUCTION

It has long been recognized that an important factor contributing to the success of a new variety of apple tree bearing fresh market fruit is its growing characteristics as well as characteristics of its fruit. Additionally, another significant factor affecting the commercial viability of a new variety of apple relates to its storage characteristics, and which are reflected by such pomological traits as fruit pressure, soluble solids, and pH to name but a few. The new variety of apple tree described herein was derived by the following methodology. The new variety ‘Regal D5-100’ was derived by a controlled pollination of the variety Huaguan (U.S. Plant Pat. No. 11,077) with the pollen from Honeycrisp (U.S. Plant Pat. No. 7,197) in spring 2007. Seeds from this cross were collected in the spring of 2008. Resulting seedling wood was budded onto NIC 29 rootstock in 2009. In 2011, these trees were planted in a research plot located near 3560 RD 5 NW, Ephrata, Wash. 98823. In 2013, ‘Regal D5-100’ was selected. Second generation trees were budded on NIC 29 in the spring of 2014 and planted in the spring of 2015 at 22064 RD 6 NW, Quincy Wash. 98848. Fruit generated from the second-generation trees have been studied and compared and it appears that all characteristics of the subsequent asexually reproductive trees remain true to that seen in the original first generation tree.

SUMMARY OF NEW VARIETY

The ‘Regal D5-100’ apple tree is characterized as to novelty by its distinctive traits from its parent varieties, Huaguan and Honeycrip. By way of example, ‘Regal D5-100’ exhibits semi-spur characteristics, exhibits upright growth habit with moderate vigor as grown on NIC 29 rootstock, is a mid-season bloomer and will allow for pollination from any other diploid apple of the same bloom season. ‘Regal D5-100’ has a tendency to exhibit alternate bearing following a heavy crop load. Fruit at maturity is medium in size, has a streaked bi-color and is slightly lopsided. The fruit exhibits four months of common storage life. The fruit is further sensitive to bruising and does not exhibit bitterpit. ‘Regal D5-100’ is susceptible to powdery mildew and is moderately susceptible to fireblight.

DETAILED DESCRIPTION

Referring more specifically to the pomological and botanical details of this new and distinct variety of apple tree, the following has been observed during the 2016 and 2017 growing season under the ecological conditions prevailing in a test orchard which is located near Quincy, Wash. All major color code designations are by reference to The RHS Colour Chart provided by The Royal Horticultural Society of Great Britain.

The parents of the ‘Regal D5-100’ are the Honeycrisp tree and the Huaguan tree. The following are some of the characteristics that distinguish the ‘Regal D5-100’ from its parents. The ‘Regal D5-100’ leaf length falls in between the length of the Honeycrisp and the Huaguan. The ‘Regal D5-100’ is more oblong in nature with a wider base and tapers at the top. Honeycrisp is more oval in nature. Huaguan is a more slender and smaller leaf than the Honeycrisp and the ‘Regal D5-100.’ The ‘Regal D5-100’ has more “teeth” on the serrated edge whereas Honeycrisp's are fewer and more rounded in nature. Huaguan's “teeth” are finer and less rounded than the Honeycrisp and the ‘Regal D5-100.’ Huaguan's younger leaves on the terminal have a much more yellowish hue than either the Honeycrisp or the ‘Regal D5-100.’ The Honeycrisp has finer (thinner) wood in its branching when compared to both the Huaguan and the ‘Regal D5-100.’ The ‘Regal D5-100’ appears to be more upright in its growth characteristics than both the Honeycrisp and the Huaguan. Both the ‘Regal D5-100’ and the Huaguan are much more vigorous than the Honeycrisp. The Honeycrisp is a very weak grower, whereas the ‘Regal D5-100’ and Huaguan have vigor similar to that of a Fuji tree.

The closest cultivar to the ‘Regal D5-100’ is the Huaguan tree. The following are some characteristics to distinguish the ‘Regal D5-100’ from its closest cultivar, the Huaguan. The ‘Regal D5-100’ leaf length longer than the Huaguan. The ‘Regal D5-100’ is more oblong in nature with a wider base and tapers at the top. Huaguan is a more slender and smaller leaf that the ‘Regal D5-100.’ The Huaguan's “teeth” are finer and less rounded than the ‘Regal D5-100.’ Huaguan's younger leaves on the terminal have a much more yellowish hue than the ‘Regal D5-100.’ The ‘Regal D5-100’ appears to be more upright in its growth characteristics than the Huaguan.
