Introduction

Cross-pollinated vegetable and field crops require isolation to assure no undesired cross-fertilization between different varieties of the same species, and between different crops in different species.  

Crop isolation can be achieved either by spatial (distance) or temporal (time) factors. 

This Internet isolation or “pinning” map is designed to allow seed growers to identify the location and the planting date of seed crops produced in California.  

Seed production personnel can electronically mark or “pin” fields from their offices to allow “real time” tracking of seed production activities.

This map is available for all seed companies and/or growers to use in order to help coordinate seed production efforts. It was developed as a result of the financial support and advice of numerous vegetable and field seed companies.

The map is not intended to be used to enforce field isolations, but rather to be used as a tool to help companies and growers work cooperatively to place and plant seed fields to assure high genetic purity. 

Users only have the ability to enter and change data on their own fields by use of confidential login ID’s and passwords.
