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.
