The diversity in
each field is measured by examining
|
|
the
effectiveness of Rps genes (pathotypes or
|
|
|
races).
|
|
| l |
Pathotype
describes a population in a field and the
|
|
|
resistance genes
it is able to overcome.
|
|
| l |
Pathotypes may
be distributed randomly across a
|
|
|
field.
|
|
| l |
The pathotypes
that will prosper are those that can
|
|
|
survive on the
varieties of soybean planted.
