No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
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) 2 ) of 11,249.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. 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.
