Nurseries & Royalties


Our breeding program operates solely on royalties received from tree sales of our varieties. We do not receive any industry levy funds, government grants or tax breaks.

If as a grower you value this important program please ensure that you pay the royalties that allow the program to continue.

You can do this by always purchasing trees from the licensed nurseries listed here. Or if you have already bought trees without paying royalties, contact us, it is never too late to catch up.

A royalty will be charged.

In detail, we use two mechanisms to protect our varieties and collect royalties.

  • PRB (Plant Breeders Rights) - This is a national and internationally legislated system that is similar to patents. It allows the breeder to control who propagates the variety, and thus a collect royalty, for a period of 25 years. It allows strong enforcement of the breeder’s rights but it has significant costs that inevitably get passed on growers. Monitoring can also be quite intrusive for both nurseries and growers.

  • Grower/Propagator agreements - This is system of business to business agreements that should ensure similar outcomes to PBR. It is essentially an honesty box system that has weaker enforcement than PBR but results in lower costs to ourselves and thus growers, and is less intrusive for growers than full PBR.

Details of the royalty status of our varieties are as follows

  • Our first releases - A4, A16, A38 - were through PBR, expired in 2008 & 2011 and are now royalty free.

  • Our second set - A203, A268, A29 - were done via Grower/Propagator agreements, we are still collecting a royalty on these varieties.
    Unfortunately over time some control has been lost over the propagation material for these varieties. This has led to a perception among some nurseries and growers that the royalty is optional, which in turn has resulted in poor levels of royalty compliance.
    However as far as we are concerned the royalty for A203, A268 & A29 is compulsory, though with weak enforcement.
    We would ask growers to only purchase these later varieties from HVP Licensed Nurseries who will charge a royalty on them.

  • Our next batch - A376, A403, A422, A447, A538 - are expected to be released in 2020. Due to the experience of poor royalty compliance with A203, A268 & A29 we will be going back to PBR. This will result in higher costs and more intrusive compliance checking for nurseries and growers. Unfortunately there not seem to be any other viable option.
