saving seeds

[rzr]

I have two kelogs breakfast seeds that germinated with sort of a brown fury stump at the base of the stem. There are leaves starting to grown from it but it is definitly stunted and is getting going a bit slower then the other plants.

These are the only ones that germinated actually. So my question is, if it produces fine later on, if I save the seeds from one of the tomatos, would they be ok seeds or would they start out like these?
