Reproductive Isolation:
1. Isolation strips
: plot of a crop which separates seed plots,
preventing crossing and mechanical mixtures.
• This strip would theoretically catch windblown pollen and
distracts insects from visiting the plots on either side of it.
2. Distance Isolation
: Try to follow this general rule, selfers should
be isolated by at least 150 feet AND an isolation strip. Wind
pollinated crossers should be separated by at least 1 mile (but
up to 5 miles), insect pollinated crossers should be separated by
at least ¼ mile AND some other barrier (or 1 mile in open land).
Once again these figures vary depending on the source of your
information.
