| Abstract: |
A female Asparagus plant which when combined sexually with a male plant produces an F 1 all male hybrid and transmits rust and Fusarium resistance to its progeny when asexually propagated. |
| Claim: |
We claim:
1. A new and distinct variety of Asparagus plant substantially as herein shown and described, characterized particularly as to novelty by its ability to transmit rust (Pucciniaasparagi) and Fusarium tolerance, when asexually propagated as well as produce an all male hybrid when combined sexually with a male hybrid. |
| Description: |
This invention relates to a new and distinct varietyof Asparagus which is a female plant and we have chosen to emphasize that fact by denominating the same with the female name "Tara" where commercial designation is necessary.
In view of our long continuing program of breeding for improvement of Asparagus plants to establish various factors such as resistance to rust (Puccinia asparagi) and tolerance to Fusarium infestation, the development of the instant plant isimportant since we have found that those characteristics are transmitted to successive generations.
We have determined this by effecting asexual reproduction for the purposes of establishing that the characteristics come true in successive generations, by both crown division and tissue culture.
Further in our program, we are constantly on the lookout for Asparagus plants in many different areas, which have resistance to rust, tolerance to Fusarium infestation, are vigorous, high headed, produce jumbo size spears, and result in largevolume production among other desirable characteristics, all looking to increase commercial production and value.
Thus when this new Asparagus plant was found to have resistance to rust, tolerance to Fusarium infestation, and also be a female plant, it was used to combine sexually with the male "Scott Howard", U.S. Plant Pat. No. 5,549 and thus the F1 allmale hybrid "Jersey Titan" was produced. This hybrid "Jersey Titan" is the subject of separate application.
The fact that our new variety was selected from the cross 14.times.30, cross No. 277, and because of "Tara's" rust and Fusarium tolerance and the further fact that those characteristics are in fact transmitted by asexual propagation, support ourselection and enhance the value of the long continuing program which we have undertaken.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a mechanical drawing showing portions of a mature Asparagus plant showing characteristic dimensions of a typical specimen of `Tara`.
FIG. 2 is a color photograph of a typical specimen of `Tara` in an observation planting showing the speciment inside view, in color and as nearly representative of such a plant as is possible to disclose the same in a reproduction of this kind,color references being those related to the Munsell Limit Color Cascade of Macbeth Division of Kollmorgen Corporation.
DETAILED BOTANICAL DESCRIPTION
As part of that program and records kept in relation thereto, we have assembled data set forth herinafter which assists us in distinguishing among the many plants produceed, the data being representative of such a plant and in this case aspecific plant "Tara".
