Abstract

A male asparagus plant which is homogenetic and transmits particularly the characteristics of male genes and which include high yield capability, resistance to rust (Puccinia asparagi), tolerance to root rot (Fusarium oxysporum) and crown rot (F. moniliforme), enabling production of male hybrids that likewise embody such characteristics.

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 as a homogenetic first selfed generation male seedling produced by self fertilization of an andromonoecious male, which transmits only male genes, and which in turn transmits particularly the quality of high yield, resistance to rust (Puccinia asparagi), tolerance to root rot (Fusarium oxysporum) and crown rot (F. moniliforme) and thereby facilitates growth of male hybrids to replace standard cultivars which are susceptible to disease.
