Pallaton Raphno® 

Pallaton Raphno® is a hybrid between Brassica oleracea (kale) and Raphanus sativus (radish). This hybrid has brought a number of impressive agronomic attributes into one cultivar, including high forage yield from multiple grazings, drought tolerance, clubroot tolerance and improved tolerance to a range of key insects.

The first new forage brassica species New Zealand farming has seen since the 1980s. Developed by PGG Wrightson Seeds under the Forage Innovations joint venture with Plant and Food Research.

THE SUCCESS OF SCIENCE

The goal of the breeding programme was to combine six stacked traits, which would perform for New Zealand farmers within increasingly challenging environments.

The six traits include:

  • High forage yields from muiltiple grazings
  • Plant persistence under multiple grazings
  • Drought tolerance
  • Clubroot tolerance
  • Aphid tolerance
  • Grazing flexibility

 

High Yielding

14% increased yield advantage relative to Goliath® forage rape in a multi-graze system (total cumulative dry matter (DM) yield from repeat harvests).

 

Clubroot Tolerance

Pallaton Raphno® has a high tolerance to clubroot. In vitro inoculation pot trials and field trials to date have shown strong tolerance to Pukekohe, Hawke’s Bay and Southland strains of clubroot. Although Pallaton is highly tolerant to clubroot it is still susceptible to other brassica diseases.

 

GRAZING PALATABILITY

Pallaton has shown increased palatability relative to forage rape and leafy turnip brassicas.

 

MORE MEAT PER HECTARE

Our trials showed Pallaton delivered 41% more meat per hectare* compared with chicory. Pallaton Raphno®: total 390 kg/ha versus chicory: total 276 kg/ha.
 
*Trial completed by PhD student Holly Phillips at Massey University. Meat per hectare data was captured over the period 17/01/2020 to 01/05/2020.

 

APHID TOLERANCE

32% increase in Aphid tolerance relative to forage rape. Pallaton also has a higher level of tolerance to White Butterfly and Diamondback Moth.

Grazing Flexibility

Graze Pallaton as early as 50 days after emergence (DAE) to maximise crop utilisation and regrowth potential. It can be deferred up to 100 DAE, however crop utilisation, regrowth potential and feed quality will be reduced. Pallaton does not have a specific maturity requirement. 

 

PERSISTENCE UNDER MULTIPLE GRAZINGS

100% increase in plant survival relative to forage rape under dryland sheep grazing management.

Drought Tolerance

38% increase in water use efficiency (WUE) relative to Goliath forage rape.
