Open Pollinated •generally refers to seeds that will "breed true." When the plants of an open-pollinated variety selfpollinate, or are pollinated by another representative of the same variety, the resulting seeds will produce plants roughly identical to their parents.

Heirloom •a plant variety that has a history of being passed down within a family or community, similar to the generational sharing of heirloom jewelry or furniture. An heirloom variety must be open-pollinated.

Choice of interesting/exciting varieties

Often lack disease/pest resistance

Interesting histories

May not grow well in different region

Can be adapted regionally

Unpredictability/ low yield

Hybrid • Hybridization is a controlled method of pollination in which the pollen of two different species or varieties is crossed by human intervention. Hybridization can occur naturally through random crosses, but commercially available hybridized seed, often labeled as F1, is deliberately created to breed a desired trait.

You CANNOT save seeds from a hybrid plant.

Genomic/Marker Assisted Cross Breeding Increased disease/pest resistance

May lack interest factor of heirlooms

Hybrid vigor/ higher yields

May not grow well in different region

Often adaptable to many regions

Inconsistency with saved seed

GMO •Genetically Modified Organism. A term used to describe an organism where individual genes for desired traits are introduced through direct introduction rather than cross-breeding. Due to confusion and misuse of the term, a better term is Genetically Engineered.

Hybrids are GMOs.

When you think about it, every living thing is a GMO.

USDA – Plant pest? • Environmental risk (ie – weedy-ness, pathogen) • Approve field trials EPA – Danger to environment? • Herbicide use • Pesticide registration (Bt corn) FDA – Danger to people/animals? • Food safety (ie – toxicity, pathogens) • Feed Safety

Plant Patent • up to 20 years protection for a unique, vegetativelyproduced variety. May be used by others in breeding programs. Utility Patent • protects a specific attribute of a plant, such as disease resistance or DNA sequence, for 20 years. May NOT be used by other for breeding. Plant Variety Protection • Protects unique seed or tuber produced plant from unauthorized commercialization. 20 years for most, 25 for perennial trees/vines. Can save seed for own use, but may not distribute until after expiration. http://www.johnnyseeds.com/about-us/about-our-seed/understanding-utility-patents-and-pvp.html

High potential for solving evolving issues

Many people still concerned/fearful

Provides rapid means to respond to diseases and other issues

Requires thorough study for safety and effectiveness

Can potentially reduce use of pesticides

Inconsistency with saved seed

Utility Patent
