DETAILED BOTANICAL DESCRIPTION
A. Genus and Species: Vitis vinifera.
B. Name: `Sarah Anne`.
C. Type/Market: Table Grape.
D. Characteristics.
1. Origin of the New Variety
About twenty years ago, some scion wood of a `Kyoho` grape vine was brought from Japan to the U.S., and was grafted to a `Thompson Seedless` grape vine in Fresno, Calif. `Thompson Seedless` is believed to be an unpatented variety. Accordingly,the parent plant from which the new `Sarah Anne` variety was cultivated was the `Kyoho` grafted to a `Thompson Seedless` rootstock. After a few years, there was enough Kyoho scion wood grown from the first grafted plant, described above, to graftseveral more `Thompson Seedless` grape vine rootstocks. It is from this second group of vines, when a mutation apparently occurred, and was noticed by the inventor as the unique variety described herein.
Then, about eight years ago, the inventor took scion wood from this mutated group of vines and grafted them to several Emperor rootstocks in Reedley, Calif. Emperor is also believed to be an unpatented variety. Each of this group of graftedvines maintained the same unusual characteristics that existed from the mutated vines. About four years ago, the inventor took scion wood from these vines and grafted them to several hundred more `Emperor` vines in Reedley, Calif. They continued tomaintain the same unique characteristics. All of the available graft wood from the patch of unique plants have been gleaned during the past two years and fifteen acres of `Emperor` grapes have now been successfully grafted over to the `Sarah Anne`.
Accordingly, thses grapes have been asexually reproduced true to the type of the original vine in all distinguishing characteristics of darker color, smaller grape, more oblong shape and sweeter taste to establish that these claimedcharacteristics are stable.
From the plants in Reedley, Calif., about 160, 5-kilo containers of `Sarah Anne` grapes were packed. Samples thereof were shipped on Sep. 2, 1999 to test reaction and marketability of the new grape.
2. Vine
The growth of the vine is of moderate vigor. It has been experimentally grafted to known rootstocks, including Emperor, and it has been grown on its own natural root. These rootstalk trials all produced vines of similarly moderate vigor. Thefoliage is somewhat sparse and certainly would not be considered dense.
A commercial `Sarah Anne` vineyard was planted using `5BB` rootstock, a commercially grown rootstock commonly chosen for its vigorous tendencies and for its ability to survive and even flourish in soils with poor water drainage and permeabilityproblems. This rootstock planting occurred in the Spring of 2000. As soon as the 5BB rootstock buds began to smell, the `Sarah Anne` buds were grafted thereto. Most of the vines reached a training wire at 42" by mid-July 2000 and were pruned backpending the installation of an open gable trellis system installed in the Winter of 2000. The vines were trained in a quadrilateral cordon design. By August 2002, average trunk size of 1.25" to 1.5" in diameter was seen. The texture of the trunk isquite woody and rough and light redish brown in color. The lateral cordons are approximately 0.75" in diameter and appear to be mature as indicated by the woody and rough appearance. The vertical canes which grew from the quadrilateral cordons in theSpring of 2002 are green and lush and bear much fruit. They have grown an average of 6 feet in length, some a little shorter and some as long as 11 feet. During late August, lignification begins to occur on the yearling shoots extending about to wherethe grape bunches are attached by the peduncle to the shoot. It is late December before the lignification extends to near the end of the shoot.
The vine is extremely fruitful. It is growing a first crop which will begin to be harvested Aug. 6, 2002. Also growing concurrently is a second crop which will yield a volume of about 20%-40% of the size of the first crop and will ripen towardthe end of September, 2002. This second crop is commercially viable in terms of quantity and quality and provides an opportunity for an extended marketing period.
The grapes and stems seem to be quite resistant to mildew. Some of the young vines have not received any fungicide application this year and show no signs of mildew except on the leaves and shoots.
3. Leaves
The leaves of the `Kyoho` and the `Sarah Anne` are similar in structure and appearance.
The leaves when mature are medium in size and range from 3" to 6" in diameter and are pentagonal in shape. If one draws a circle around the leaf, one would find that the leaf is about as wide as it is long except for a deeply cut "U"-shapedsinus where the petiole attaches to the leaf. The petiole is light green and is about 1/3 the length of the width of its respective leaf. The veins in the leaf are also green and protrude prominently from the surface of the underside of the leaf, whichhas a matte dull texture. The face of the leaf is relatively smooth and glossy. The new growth of leaves at the end of the shoot are light green in color and covered face and back with white prostrate hairs, no erect hairs. As the newly formed leavesmature, they lose their prostrate hairs, first on the face of the leaf and finally on the back of the leaf. As the surface of the leaf matures, the face of the leaf becomes somewhat glossy and becomes a darker, deeper green in color.
4. Shoots
As the shoots develop both surfaces of the newly formed leaves at the tip of the shoot are covered with dense prostrate hairs.
Each new leaf has another bud at the base of the petiole where the leaf attaches to the shoot. Almost every new leaf also has a tendril attached to the shoot on the opposing side of the shoot from where the petiole is attached. The phenomenonof tendrils opposing each leaf seems to change as the shoot nears the point of attachment on the cordon from which it is growing. At the tip of the shoot where the new growth occurs the color of the shoot is light green. The shoot becomes slightlydarker green as it approaches the main cordon and can have some streaks of red along the way. Almost every tendril has 3 tips and, when mature, is 5"-6" long. As you follow the shoot from the tip to the cordon you will observe the secondary bud at thebase of each petiole sprouting a new shoot. These secondary shoots can grow quite long as the main shoot approaches the cordon. The secondary shoot varies in length and may sometimes exceed 2 feet.
5. Flowers
In 2000, the `Sarah Anne` grape vine's flowers bloom began around the 5th of May, and finished quite evenly about a week later. The flowering nodes are numerous and the pistols are almost white in color and are easily visible against the lightgreen background of the bunch cluster. Bunch clusters are generally 6"-7" in length. The crop was quite heavy. The bunches were thinned to an average of one bunch per chute, sixteen to twenty-six bunches per vine. After the bloom, the grape buncheswent through their own natural berry thinning process called "shatter." The shatter that took place this year was extreme. Many branches were left with fewer berries than were needed to develop into well formed, appropriately sized bunches. Thisexcessive shatter may have resulted from experimentation with bunch thinning, tipping and bunch shaping. The `Sarah Anne` vines of the control group seemed to have a more consistent berry set but still less than desirable.
6. Ripening
Harvesting of the `Kyoho` occurred in Sanger, Calif.
Grape maturity factors indicate that some of the `Sarah Anne` could have been harvested at the same time as the `Kyoho`, however, the `Sarah Anne` seems to hold well on the vine and can be harvested at a later date without compromising quality.
Harvest of a first crop usually begins during the first week of August and concludes during the first week of September. A second crop can usually be harvested beginning the last week in September and conclude during the later weeks of October.
7. Fruit
a. Berry
1. Shape: Somewhat oblong, tapering slightly toward the stem of the grape. When the `Sarah Anne`s very round shape is compared to the `Emperor`, the `Emperor` has sort of a tear-drop shape, rather narrow on the stem end and wider on the bloomend. A nicely shaped `Thompson Seedless` table grape, on the other hand, is almost cylindrical in shape, with the diameter of the stem end nearly equivalent to the diameter of the bloom end with a slight increased diameter or bulge toward the middle.
2. Size: Grape size may vary considerably from bunch to bunch from about 11/16" to 11/8" in diameter. The length will vary from 12/16" to greater than 11/4". Compared to the `Sarah Anne`, both the `Emperor` and `Thompson` table grapes aregenerally smaller in diameter and longer.
3. Seeds: Both the berry of the `Kyoho` and the `Sarah Anne` contain seeds. The `Sarah Anne` grape generally contains from 1 to 4 seeds, but most commonly 2-3 seeds per grape. Occasionally one may find a `Sarah Anne` grape with no seeds. Theseeds are about 3/8" long and 3/16" wide, sort of pear shaped and straw colored. From a sample of 50 randomly selected berries there was an average of 2.86 seeds per grape. The average weight of each grape was 9.91 grams. The average weight of eachseed was 0.1349 grams. The ratio of grape mass to seed mass is 24.49:1.
4. Color: The color of the mature `Sarah Anne` grape is much darker purple, almost black, and much sweeter than its parent grape, the red colored Kyoho. Compared to the almost black `Sarah Anne` seeded table grape, the `Emperor` is a red seededtable grape and the `Thompson Seedless` is a white seedless table grape.
5. Skin: The skin of the `Sarah Anne` is of medium thickness and is covered with a dull waxy bloom. This waxy bloom helps to protect the berry from disease and rain damage. The `Sarah Anne` grape skin is easy to peel from the light greentranslucent flesh of the grape. This is an attractive characteristic as some consumers customarily peel their grapes before serving. The skin shows no signs of tendency to split or crack. The skin of the `Sarah Anne` is what is commonly called a slipskin. It is a soft berry that is easily peeled as is the custom among some ethnic communities. The `Emperor` and `Thompson Seedless` are more of a crisp type of berry that will burst in your mouth upon biting down and do not easily peel. The `SarahAnne` berry will softly yield to the pressure of biting down and be gently crushed.
6. Bunch Size: The `Sarah Anne` generally produces bunches of a medium size. A common bunch would consist of between 60-90 berries.
7. Taste: The taste of the `Sarah Anne` grape is very fruity and very sweet, almost to the point of being syrupy sweet. It has a very fruity aroma that people find pleasant. But, the sweet-fruity aroma also tends to attract birds that caninflict significant damage to the grape crop prior to harvest. Harvesting the `Sarah Anne` takes place when the brix level of the grape exceeds 20. Both `Thompson Seedless` grapes and `Emperor` grapes are harvested around the 17 brix level which yieldsa moderately sweet grape with no distinctive flavor.
The `Sarah Anne` grape is very juicy and somewhat soft. When held between one's fingers the grape will readily yield to pressure unlike the crispness of a `Flame Seedless` or `Thompson Seedless` grape. The texture of the flesh is soft.
8. Culturing: Cultural practices performed for both the `Kyoho` and `Sarah Anne` varieties are similar. They are both spur pruned with a similar number of spurs branching off of two opposing cordons.
The `Sarah Anne` vines are grown utilizing a quadrilateral cordon on an open gable trellis design. This design successfully opens up the vine and allows for sun light penetration and good air circulation. The vines are spur pruned during thedormant season and copper is applied to the end of each spur to prevent fungi infection.
Prior to bloom the vines are crown suckered. A couple of weeks later leaves are pulled and small clusters are removed to allow for no more than 2 bunches per shoot or 16 to 26 bunches per vine, depending upon the health and vigor of the vine. After the bloom the clusters of grape go through a shatter. In some instances the shatter is excessive not leaving enough berries in the cluster to form a well formed cluster or bunch. In any case no bunch clipping or removal of berries is necessary toallow for proper sizing of berries.
Petiole analyses are performed by a lab at harvest time to determine plant nutrient needs and hence the appropriate supplements are applied.
9. Growth/Vigor: Neither the `Sarah Anne` nor the `Kyoho` is a very vigorous growing vine as compared to many other table grapes. Their vigor is comparably similar. They both seem to have cropping tendencies as they are very fruitful andproduce many medium sized bunches.
10. Storage: The `Sarah Anne` grape seems to store quite well. A few boxes were stored through last winter and brought out of cold storage in late April of 2000. Even though a portion of the grapes in the containers was infested by fungi androt, there was a surprising amount of grapes remaining which were solid, clean and perfectly fit for human consumption.
11. Distinctive Characteristics: The `Sarah Anne` characteristics were compared with the `Kyoho` grapes harvested Aug. 5, 2000 in Sanger, Calif.
The grapes of the `Kyoho` are generally lighter in color, more of a deep red than the almost jet black color of the `Sarah Anne` grapes of comparable maturity.
On average, the grape size of the `Kyoho` was slightly larger than the average size of the `Sarah Anne`.
The shape of the `Kyoho` grape is very round in comparison to the `Sarah Anne` which is a bit oblong, tapering toward the stem of the grape.
The most significant difference was in the taste. Both are good tasting. The `Kyoho` has a similar flavor, but is quite muted in relation to the `Sarah Anne`. The `Sarah Anne` flavor is much more intense, full and robust: it is so sweet thatit is almost syrupy.
The average Brix (according to the Brix Scale) of a sample of five separate branches of the `Kyoho` ranged from a low of 15.degree. to a high of 21.degree.. The average Brix of a sample of five bunches of the `Sarah Anne` picked Aug. 6, 2000ranged from 23.degree. to 27.degree.. This is a considerable distinction and, at 5.degree. to 8.degree. higher than its parent the Kyoho grape at the same harvest date, was very noticeable upon taste testing.
