An Asparagus Plant having predominately female characteristics, with resistance to rust (Puccinia asparagi), tolerance to root and crown rot (Fusarium oxysporum) and (F. moniliforme), vigorous through long life, having a largest stalk of 21.4 mm diameter, mean diameter of three largest stalks being 20.8 mm, an average of 26 stalks per plant and a stalk vigor index (No. X (Mean Diameter).sup.2) of 11,249.
A new and distinct variety of Asparagus Plant as herein shown and described, distinguished particularly as to novelty by its unique combination of predominately female characteristics, which transmit high yield, resistance to rust (Puccinia asparagi), tolerance to root and crown rot (Fusarium oxysporum) and (F. moniliforme), maintaining vigor through long life, enabling growth of hybrids where standard susceptible cultivars cannot be grown profitably.

This invention relates to a female asparagus plant which is one selected by us as a result of an intense and continuing program of development of asparagus, to improve resistance to disease and increase productivity.
The instant plant which is denoted in our records as No. 53, is also identified as "Inez" and was selected from a field of Mary Washington which has been grown for more than thirty five years, it is undoubtedly basically of that background being an unpatented variety, though differing in many respects.
We have asexually reproduced our variety "Inez" by crown division and also by tissue culture and find that it comes true in successive generations, with the characteristics of resistance to rust (Puccinia asparagi), tolerance to root rot (Fusarium oxysporum) and crown rot (F. moniliforme).
In the accompanying drawing we have disclosed in FIG. 1 a typical stalk of our new variety with certain of the dimensions and other elements directly indicated in black and white.
In FIG. 2, we have shown in color as nearly as possible representative of a typical plant, one of our new variety, with the color compared by us to the Munsell Limit Color Cascade and in our opinion as nearly accurate as can be reproduced in an illustration of this kind with notations referring thereto, the photo having been taken under normal daylight conditions in the field where grown.
Data which we have accumulated in reference to the instant variety, is summarized in the following table, which sets forth some of the information which enables us to identify the same and compare it with other varieties as well as those with which it has been crossed to produce hybrids such as that known as "Jersey Centennial" the subject of U.S. Plant Pat. No. 4,998.
