| description | Due to the restricted genetic diversity among current asparagus cultivars, wild relatives are of particular interest as a source of resistance. In this study, seventeen cultivars and wild relatives were tested for their resistance to <i>Fusarium oxysporum</i> in the seedling test. Two isolates differing in virulence (single spore lines with high and low virulence) were used for testing. Most of the tested genotypes showed high infestation, whereby <i>Asparagus aethiopicus</i> caused no browning of the roots or growth depression. This wild relative was evaluated for its defence response after infection with <i>F. oxysporum</i>. For comparison, the wild relative <i>Asparagus densiflorus</i> and <i>Asparagus officinalis</i> cv. Thielim were tested. Like <i>A. densiflorus</i>, <i>A. aethiopicus</i> showed accumulation of hydrogen peroxide as a defence mechanism, while <i>Asparagus officinalis</i> cv. Thielim showed no storage of hydrogen compounds. |
