These are TPS collections from individual varieties.  Self pollinating tetraploids will be mostly self-pollinated, with a little bit of outcrossing.  All other types will be substantially to completely outcrossed, meaning that the seed contains half of the genetics of the listed parent.  If I have had time to do it, pictures show the results of growing the TPS (multiple phenotypes).  If not, it just shows the parent type.  Regardless of what the picture shows, all TPS produces diverse results.
