The present invention relates to a new and distinct variety of hops which matures rapidly, has excellent bitterness and aroma, and exhibits increased disease resistance, particularly toward downy mildew and gray mold.
The variety is further characterized by being of relatively low height, having a reddish-purple crista color, and a main vine which is reddish-green. The cones are greenish-yellow and change to pale green as they mature. The cone shape is elongated spheroid and large. The plant, which is plagiotropic, has a very high content of humulone and farnesene and a very low content of cohumulone.
The new plant originated from a cross-breeding in 1983 of the mother, Sorachi-ace, and father, seedling of Saaz from open pollination, at Hokkaido Center, Plant Bioengineering Research Laboratories, Sapporo Breweries, Ltd. Due to the hybrid character of this plant, its unique and valuable characteristics can be assured to be retained only through asexual or vegetative propagation.

DETAILED BOTANICAL DESCRIPTION OF THE PLANTSorachi-Ace is a proprietary variety developed by Sapporo (registration pursuant to the Seed and Seedling law applied for in 1983, registered as a variety in 1984). Saaz is a general term used to refer to a group of hop varieties originating in Czechoslovakia, which includes several varieties derived from Oswald Clone No. 3,172,114. It is not known which specific Saaz varieties were the parents of the Saaz seedling which is the pollen parent of Furano No. 18.
The following is a detailed description of the characteristics of the new variety as observed at the same Research Laboratory noted above. Color designations are made by reference to J.H.S. Color Chart (Japan Horticultural Scale) and R.H.S. Colour Chart (Royal Horticultural Society), except where common terms of color definition are employed.
The new variety was propagated and is maintained at Sapporo Breweries, Ltd., Hokkaido, Sorachi-gun, Kamifuranomachi Higashi Line 4 Number 25, Japan. The multiplication of the plant was performed by separating roots from existing stock and then cultivating and propagating at the test field.
The hops plant, "Furano No. 18", has been found to be stable and the clonal progeny of this plant have been found to be identical to the original selection in all distinguishing characteristics.
The following represents a breeding history.

______________________________________
The novel plant of this invention was under final test and observation for two and one-half years; a period from April 1990 to September 1992, at which time the selection had been multiplied to a population sufficient to occupy five acres.
The plant of this invention is an early ripening variety-mesophytic type, suited for cultivation in Hokkaido and the northern area of Tohoku, and is suitable for large scale mechanical picking. Growths are medium in thickness and the height is low. It is resistant against downy mildew and gray mold, is easy to cultivate and has an excellent quality as it contains very little cohumulone, which includes .alpha.-acids, a main component of bitterness, but much humulone and farnesene.
The new variety is particularly suitable for growing in Hokkaido, the northern part of Tohoku. This variety is also advantageous as it requires no excessive growth control as is the case with Shinshu-wase, the predominant species. The new variety also requires no lowering of vines or picking of primary side branches.
The morphological characteristics of the new variety are described hereinbelow, and are summarized in Table 1 following thereafter.
The general growth form of the new variety is clavate, with the mature plant being of medium height. The color of the young shoots is (ISCC-NBS) reddish-purple with the angle of the shoot to the ground being squint. The main vine is (ISCC-NBS) reddish-green in color with the crista color being (ISCC-NBS) reddish purple.
As used herein, the term "squint" denotes a range of angles of the stem to soil of between 30.degree. and 70.degree.. The term "creeping" refers to a range of angles of from 0.degree. to 30.degree., and the term "straight" refers to a range of angles between 70.degree. and 90.degree.. The term "crista" denotes the line connecting the six angles on a cross-section of the hexagonal stem of the plant.
The degree of twining of the main vine is medium with a glabrate degree of node hair. The length of the internode is medium with a medium number of nodes.
The length of the internode provided is for the internode at approximately 1.5 m. from the ground for a vine which has reached a height of 2.75 m. An internode of under 30 cm. is "short"; from 30-40 cm. is "medium"; and 40 cm. or more is "long". The internode of Furano No. 18 averages 35 cm., with the range being from 29-49 cm., and is therefor of "medium" length.
The lateral branching of the new variety is medium in length with a medium degree of branching. The location of inflorescence is at the tertiary branch with the density of inflorescence being medium to dense. The storm resistance of the lateral branching is medium to strong.
The increased extent of lateral branching of Furano No. 18 appears to be an inherent feature of the plant. Shinshu-wase, by comparison requires bending of the stem so that the vine will grow laterally and/or clipping of the upper stem in order to stop vertical growth and promote lateral growth, so that the cones on the branches below will be exposed to sunlight. Due to the typically excessive growth at the top portion of the vines of Shinshu-wase, the cones below are shaded. Because of the increased external lateral branching in Furano No. 18, the foregoing measures are not necessary to expose the lower cones to sunlight.
As used herein, the word "medium" when used to describe the length of lateral branching denotes a length of between 60 and 140 cm. The average length or lateral branching of the present plant is 135 cm., with a range of between 110 to 165 cm. Thus, it is "medium" in length. The term 37 short" is used to denote the range of lengths up to 60 cm., and "long" denotes a range of from 140 cm. and over. The "degree of branching" is estimated by visual observation as is the "density of inflorescence".
The leaves are (ISCC-NBS) light-green in color when young, and remain so when mature. The leaves have a palmate blade form with seven lobes. The sinus cleft has a medium depth and the marginal serrations are of a serrated form. The form of the blade base is close.
The color of the young leaves and the mature leaves is "dark yellow-green" which is 3508 on the B.H.S./J.H.S. Color Chart.
The cones are yellowish-green (ISCC-NBS) in color and are of an elongated spheroid form. They are large in size. The number of blacts and blacteroles is medium and the cone weight is also medium. The number of cones per vine and the weight ratio of cones to foliage and vine may each be characterized as medium.
The blacts are (ISCC-NBS) yellowish-green in color and are of an oval form. The tip form is acute with a medium length. The length to width ratio is medium.
The blacteroles are of a (ISCC-NBS) yellowish-green color and are ovate to ellipsoid in form. They are medium in length with a medium length to width ratio.
The strigs are of medium thickness with a medium density of flowers. The lupulin is (ISCC-NBS) yellow in color and medium in size. The lupulin blacteroles are medium to abundant in number.
The new variety exhibits a mid-stage of flowering, with cone production also occurring at mid-stage. Ripening also occurs at mid-stage.
The new variety is, as noted above, disease-resistant and is, in particular, resistant to downy mildew. In more detail, the stem is resistant, the leaf is mildly resistant and the cone is resistant. The new variety is also stunt disease resistant.
The new variety has a resin content such that a medium content of resins may be noted. It has a medium content of .alpha.-acids with a medium to high .beta.-fraction. The new variety has a medium content of hard resins with a high ratio of .beta.-fraction to .alpha.-acids. The stragebility of .alpha.-acids is medium.
The .alpha.-acid constituents may be described as follows. The humulone content is very high, while the cohumulone content and adhumulone content are each low. The new variety, thus, has excellent bitterness.
The new variety also exhibits a medium degree of aroma, with a medium content of essential oils.
