Self Harvested Seeds v The Packet Jobbies

[Emagggie]

Does anyone have an opinion on whether self harvested seeds produce plants of the same standard as seeds bought in a packet ?
I have found it's generally ok for flowers, but I wondered about produce.
This will be my first year on the allotment, so I can't try any till I've grown some !   ???  :)
All opinions gratefully received.

I think many plants do produce quality seed, but two things to look for are cross-pollination and inbreeding. Unless a flower is self-fertilised, then it needs to be hand-pollinated and protected from 'foreign' pollen sources to ensure that the seed is true. Information I have on sweet corn suggests that if you have less than 200 plants, the strain is liable to deteriorate due to inbreeding. I don't know how true this is; I intend to keep my own seed for one season at least, and possible buy again the following year. the other thing to watch out for, of course, is F1 varieties.

Ah yes. Thanks, Robert.
