Linda; When I mean second generation I am speaking of
crossing the offspring of the first with each other.
This should produce the greatest diversity. Note, as
you probably know, the same cross but reversing the
plant that is pod parent will give different results.
I like to think of the pod parent as the main
contributor to growth habits (physiology and
metabolosm) because of the cytoplasmic inheritance.
Also don't give up on plants that seem infertile the
first year. Fertility usually increases with time.
Also poor growers can develop into better growers as
time goes by. I suspect both of these instances are
due to cells weeding out chromosome artifacts that
interfere with cell division and that may have
occurred with an initial wide cross.
