The Importance of Open Pollinated 
Seed in a Climate Change Era
OP Seed Definition 
An outcome of human selection for specific traits 
during which plants are selected and pollinated in a 
series of crops. Keeping the variety true to form.
Regional Climate Conditions of 
OP Seed 
New Open Pollinated Variety 
During repeated selection new plant varieties are 
developed as certain traits become dominant, 
including the region's climate conditions.
Types of OP Seed 
 Heirloom 
 Heritage 
 OP 
How they come to market now 
and who they are developed for.
Controlled Environment 
of Hybrid Seed 
New F1 Hybrid 
Hybridization of seed is accomplished in 
controlled conditions by crossing two seperate 
varieties for creating a desirable set of traits in 
the daughter plant.
F1 = No True Form 
 No purpose in saving seed from year to year. 
Hybrid varieties have no regional connection to 
climate 
 Where they are developed and for what type of 
market 
My Favorite Carrot 
from Last Year
How We Can Help Maintain Regionally 
Specific Seed 
We support the process of adapting OP varieties to 
our changing climate conditions by purchasing OP 
seed from small seed suppliers involved in OP seed 
development.
Other OP Seed Benefits 
Beyond seed development for Regional Climate Conditions 
 Seed Saving and Sharing is possible because they 
come true to form and in many cases are not 
(Heirloom and Heritage) patented. 
 This translates to opportunity for continuous(year-to- 
year) food security of healthy crops. 
 Higher nutrional values and taste better!
