Benefits of technology

[0005]This invention relates to a new and distinct homozygous-male asparagus plant designated as ‘NJ22-34’. Plant ‘NJ22-34’ possesses several desirable traits including vigorous growth habit, resistance to rust (Puccinia asparagi), and good field tolerance to root and crown rot (Fusarium oxysporum) and (Fusarium mondiforme), respectively, as compared to its progenies.

Problems solved by technology

Of course, the presence of these diseases aversely impacts the yields and therefore the profitability of the product.

Embodiment Construction

[0008]An extensive program of asparagus plant development, carried out at a cultivated area in the vicinity of Bridgeton, N.J. and New Brunswick, N.J. has resulted in the development of the asparagus hybrid plant ‘NJ22-34’ with many desirable traits. ‘NJ22-34’ was produced by self-fertilization of an andromonoecious male plant known as Asparagus Plant No. 22 (U.S. Pat. No. PP4,999). Asexual reproduction of ‘NJ22-34’ has been conducted via tissue culture in a laboratory in New Brunswick, N.J.

[0009]Asparagus (Asparagus officinalis Linn.) is a dioecious species with individual plants being either male or female in sex. In addition to differences in morphology “cultivars” may also differ in local adaptation, yield, disease resistance, and longevity. Desirable cultivars are developed by crossing of elite male and female parents. Both male and female parents transmit traits such as disease resistance, yield, and spear morphology to their progenies. ‘NJ22-34’ is produced by self-fertilizat...

Abstract

A new and distinct asparagus (Asparagus officinalis Linn.) plant denoted ‘NJ22-34’ which is homozygous for male sex gene was developed through extensive breeding and selection. Asparagus hybrid ‘NJ22-34’ has many desirable traits including homogenous in male genes, good resistance to rust (Puccinia asparagi) and good field tolerance to asparagus root rot (Fusarium oxysporum) and asparagus crown rot (Fusarium moniliforme). Because ‘NJ22-34’ is a homozygous-male plant all its F1 progenies will be male plants. This invention relates to the plant and plant parts of ‘NJ22-34’. The invention further relates to hybrid asparagus seeds and plants produced by crossing asparagus plant ‘NJ22-34’ with another asparagus plant.

Description

[0001]Latin name of the genus and species: The Latin name is Asparagus officinalis. [0002]Variety denomination: The varietal denomination is ‘NJ22-34’.CROSS REFERENCE TO RELATED APPLICATIONS[0003]This application is related to co-pending plant patent application Ser. No. 11 / 431,187 entitled GENOTYPE OF ASPARAGUS PLANT NJ 44P which is owned by the assignee of the present invention and is filed currently herewith.BACKGROUND OF THE INVENTION[0004]For an asparagus plant to be commercially viable and profitable, good yield is essential. It is well known that asparagus is susceptible to a number of diseases. Among the most devastating are rust caused by Puccinia asparagi d.c., (Kahn et al. 1952), crown rot caused by Fusarium oxysporum and root rot caused by f. Proliferatum (syn=f. Moniliforme) (Johnston et al., 1979; Guerrero et al., 1999). Of course, the presence of these diseases aversely impacts the yields and therefore the profitability of the product. Accordingly, resistance to these...
