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 hybrid of asparagus plant as herein shown and described, characterized as to novelty by the unique combination of a male hybrid which has tolerance to rust (Puccinia asparagi), root rot (Fusarium oxysporum), and crown rot (Fusarium moniliforme), of substantially improved values, with a high yield of high quality spears, the spear tips remaining tight longer than those of standard cultivars and not opening when the spear is long being noticeably unaffected by hot weather, and substantially greater quantities of jumbo and marketable spears produced as compared with other varieties.
