In 2000, CCRRF began seeking protection for new rice varieties in the form of US Utility Patents. This decision, was made in response got growth in the biotechnology sector and the use of CCRRF rice varieties in private genetic engineering/breeding programs. Use of these varieties for research purposes requires a Material Transfer Agreement (MTA) from CCRRF.
In November of 2017, in response to growing contamination with weedy red rice and non-compliance with existing seed laws, the CCRRF Board of Directors amended the policy on the use and planting of seed of CCRRF rice varieties as follows:
- Only classes of certified seed of CCRRF rice varieties may be planted.
- All restrictions associated with US Plant Variety Protection Act (PVP) must be followed (e.g. varieties to be sold as a class of certified seed only). Possible violations will be referred to the California Department of Food and Agriculture (CDFA) for investigation.
- Foundation Seed of CCRRF rice varieties will only be allocated through the California Crop Improvement Association to California rice growers who have been approved to produce certified classes of rice seed.
- In accordance with state seed law, sellers of rice seed must also be registered with CDFA.
- Foundation Seed cannot be resold or transferred without written permission from CCRRF.
- Purchasers of Foundation Seed are now required to sign the Material Transfer Agreement for patented rice varieties. All of their customers must be notified of the restrictions on the use of seed of CCRRF varieties.
CCRRF initiated a voluntary and aggressive testing program of foundation seed for the presence of the Liberty Link Trait that was discovered at trace levels in Southern US long-grain rice in 2006. This included GIPSA approved third party PCR testing for the LLRice601 event, any Liberty Link trait (35S::bar), and sampling and testing by USDA-APHIS. Results involving a total of 98 pooled PCR tests were non-detect on all samples. CCRRF foundation and basic seed samples have been tested annually as required by the California Rice Commission have all been non-detect.
