Studies on the Identification of Resistance to Fusarium oxysporum (Schlecht.) in Different Genetic Backgrounds of Asparagus officinalis (L.) and Its Defense Responses

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