Parsnip Variety Trials

These field-day notes report on a Parsnip variety trial, conducted from June to December 2011, in the Cranbourne area.

Previous research has implicated Pythium species in parsnip root rot.

During the trial 12 parsnip varieties and a Hamberg parsley were evaluated for disease resistance, yield, foliage colour, vigour and susceptibility of seedlings to Itersonilia fungal leaf spot. Itersonilia is often associated with parsnip canker.

Conclusions:

• The parsnip varieties Javelin and Albion had good yields and healthy roots. Javelin had the highest proportion of healthy roots and a lower incidence of Itersonilia fungal leaf spot on seedlings compared to the growers’ own variety.

• Parsnip varieties 302-9, Melbourne, White Skin, Standard, Moonshine and Hollow Crown had the highest total yields.
• Albion had the lightest coloured foliage, whilst foliage of 302-9, Lancer and Javelin were the darkest.
• Generally, Albion had the shortest foliage whilst foliage of 302-9 was the tallest.
• Varieties Albion, Thunder, 302-9, Javelin, Moonshine and Peace had the lowest incidence of Itersonila on seedlings.
