Application July 16, 1946, Serial No. 683,843

1 Claim. 1

The present discovery relates to a new and distinct variety of grape vine, a chance seedling which I found growing in my vineyard between a Guava and a Feijoa. The dominating characteristics of novelty lie in the extreme vigor of its growth and unusual, mild, sweet flavor of its fruit.

To illustrate its vigorous habit of growth, it may be noted that in the first season after discovery, the Vine made a growth of about fifteen feet, while other seedlings growing under com parable conditions grew only twelve to eighteen inches. Upon making this observation, the seedling was removed and planted to itself the early part of the year. vIt bore no fruit that year, but made a good growth of about twenty foot spread. In the next season of following year, it bore only a few bunches of grapes but doubled its growth.

These grapes had a dark slipskin, somewhat ak n to Concord type, and were of good flavor, medium round in shape.

In the following year, still under careful bservati-on, the vine reached a sixty-foot growth, advancing to one hundred foot spread in the following season, and a heavy hedge up to ten feet at each end.

Each of the preceding years I pruned the vine back some and this season it stands at about one hundred ten feet spread and has on it, as nearly as I can determ ne, about 800 clusters of grapes, after thinnin them out about 50%, of oblong shape in distinction to the short clusters of the Concord type. This remarkable h bit of growth thorou hly demonstrated to me the vigor of the new variety.

In flavor, it is dec dedly mild and delicious as compared with the Co cord variety, approaching more that of the black Muscat.

The trunk of the vine is approximately eleven inches in circumference with rough or shaggy bark, a size wh ch is not so great considering its enormous growth.

The foliage resembles the Concord and Golden Muscat though the leaves are not quite as large as the Concords.

The nodes are about six inches apart and strong. The canes remain green longer than those of the Concord before turning brown and are heavier than Concords; the tendrils are much heavier and stronger. The hardiness of this new variety is outstanding when compared with twenty diiierent varieties grown in the same vineyard.

As for the fruit, the grapes are of medium size, blackish with maroon cast; slip skin, with mild,'sweet flavor and medium firm, juicy flesh; formed in clusters about seven inches long, quite compact and uniform. The peduncle is quite heavy and strong; the clusters are all shaded by comparatively dense foliage.

By way of comparison with the variety of Campbell Early, the characteristics of which are given in Hedrick, Systematic Pomology, pub lished 1925, by MacMillan 00., N. Y. (at pages 398-399), it may be stated that while the tendr1ls on both varieties are bifid and trifid, in the case of Campbell they are short while in my variety they are long and strong. In Campbell, the under surface of the leaves is bronze, whereas in mine they are greenish gray. C mpbells petiolar sinus is shallow and wide, in mine deep and narrow or closed to ether sometimes; Campbells lateral sinus is wide or of notch shape, while in mine it is deep and narrow; the berries of Campbell are oval and dark purplish-black, and in m ne they are round and dark with maroon cast. The seeds are small in my grape and generally less in number than in Campbell.

This new variety has been asexually reproduced from root cutt ngs and in all progeny, the characteristics herebefore noted come true to form.

In the drawing, the figure illustrates a specimen of a cluster of the berries and specimen of the foliage,
