APFIP operates an independent, secure and efficient evaluation network, which encompasses the major temperate tree fruit growing regions of Australia. Independent and effective evaluation gives growers the information they require to make balanced decisions on variety choice relevant to their growing region, climate and business operations.
APFIP is an independent evaluator of varieties and is not a variety manager in Australia. This ensures there is no conflict of interest when performing the evaluation role.
The nature of variety management has changed considerably since APFIP came into being. Third party control of varieties will become more prevalent in the future.
Evaluation data ensures both the growers and variety owners/agents have valuable information about the performance of the variety in specific growing regions.
The National Evaluation Scheme for pome fruit was developed in 1997 by a cross-sector technical advisory group comprising APFIP representatives, growers and Government technical staff.
An evaluation process was established and an evaluation network developed around regional evaluation groups of grower and advisory body members who operate under the control of APFIP.
Within each regional evaluation group there are one or more regional custodians upon whose property the trees are planted and managed for evaluation, under agreement with APFIP.
Sites have been established in growing regions based on input from growers. With so many microclimates in each area it is important to have sites in areas that reflect as near as possible the average local conditions and soil types.
These evaluation sites are planted as part of existing orchards to reflect commercial conditions. The sites are not public access and all members of the evaluation groups sign non-disclosure agreements with APFIP. APFIP also signs contracts directly with the variety owner. All trees supplied to the sites are coded and the evaluation group members are unaware of the variety name or owner. No interest in the material is vested to the custodian or APFIP – it always remains the property of the owner.
Varieties remain in a site for a maximum of seven years. During this time the varieties are thoroughly tested for suitability to that climate. After this period of required testing they will be removed as part of the ongoing security requirements.
The evaluations are carried out in different growing regions to provide performance indicators that growers can use as a guide in selecting varieties and rootstocks that are appropriate to their particular business operations.
The collection of consistent data is very important in comparing varieties and rootstocks as grown in different growing regions. The rootstocks M26 and M9 are the standard rootstocks for all sites.
The growers in the evaluation groups are obviously very busy with harvest at the time when most information needs to be collected. APFIP directly contracts information collectors or observers to work with the groups to ensure that all the required data is gathered.
Data is collected throughout the growing season and use of this information is controlled by agreement with the variety owner/agent.
There are seven evaluation sites across the key growing regions nationally:
- Stanthorpe, QLD (August 1998)
- Orange, NSW (August 1998)
- Ardmona, Goulburn Valley, Vic (August 1998)
- Lenswood, Adelaide Hills, SA (Aug 1998)
- Huon Valley, TAS (August 1999)
- Yarra Valley, Vic (August 1999)
- Batlow, NSW (August 2000)
- Manjimup, WA (August 2000)
All these evaluation sites operate as secure areas with no public access.
