Asparagus plant -- `Jersey General`
There is disclosed a high volume producing Asparagus plant having a very good tolerance to Fusarium infestation, where other commercial asparagus cannot be grown profitably, very high production of marketable spears and excellent volume of jumbo spears with quality maintained even in hot weather, the plant being vigorous, high headed and well adapted to light sandy soil.

This invention relates to a new Asparagus plant which we have developed during a long continuing program having many different objectives, some of these relating to the production of plants which are resistant to diseases, have high quality spears, grow in various kinds of soil and produce greater quantities of jumbo spears.
The instant hybrid which is described in detail herein, we have chosen to designate as "Jersey General" for commercial identification since it is a male plant and is an example of our program with some particularly outstanding attributes.
The plant herein referred to, denominated as above noted, is a vigorous, high headed plant especially well adapted to light sandy soil found in southern New Jersey, where it has been grown, establishing its ability to produce greater quantities of jumbo spears than the variety "Greenwich", which is the subject of U.S. Plant Pat. No. 5,550.
DESCRIPTION OF THE INVENTIONIn addition, when compared with another variety which we have developed and known as "Jersey Giant", the subject of U.S. Plant Pat. No. 5,551, our new plant provided a sixty-five percent greater yield as recorded over a two year period, data for the comparison being set forth hereinafter, data for other asparagus plants developed by us also being included.
Under other conditions as when the soil is a heavier sandy loam than the sandy soil referred to, which was Fusarium infested, near New Brunswick, N.J., our new plant produced thirty-five percent more jumbo spears than the next highest producing cultivar, and a total yield one hundred sixty-nine percent more jumbo spears than the average of a large number of other hybrids. The total marketable yield of our new hybrid was seventy percent greater than the average of sixteen other hybrids.
Tight spear tips which do not open readily in hot weather are another distinguishing aspect of our new plant, where other cultivars are prone to do so, resulting in lower spear quality.
We have found it very helpful to assemble data of many different kinds in view of our continuing development program, such data enabling us to not only distinguish but to direct our efforts to effecting the production of most improved plants.
We have caused our new plant to be asexually reproduced by crown division and found it to come true in successive generations.
In the accompanying drawing,
FIG. 1 discloses some of our data as applied to a typical plant,
And in FIG. 2, a color disclosure is provided, wherein the colors are described in reference to the Munsell Color Limit Cascade of Kollmorgen Corp., Baltimore, Md., and as nearly true as a photograph of this kind can provide.
As will be understood only representative data is supplied so that comparison with other plants described by us, may be made and assist in identifying our plants as well as distinguish from existing plants previously developed both by us and others.
