An S1 allows you to see the genetic variation that exists within the mother plant. If an S1 is all over the map, you can rightly assume that trying to zero in on a given expression will only increase in difficult when being bred to a male.
When breeding to a male, you introduce new genetic information and see blends of the two parents, naturally.
Any S1 will have variations reflecting only the genetic make up of the mother. The more poly-hybrid the mother, the more you can expect to see variations, as a rule of thumb. There can be plants found that are better in some attributes than the mother cut - but also find plants that are lacking certain attributes...
When an S1 line produces consistently better plants than herself - it's a good idea to try and pair her with a studly male - for the sole purpose of progression, not necessarily for pheno replication...
