Re: HYB: repeat cross results

From some of the material I read last year, this may also have
implications for differences in seed dormancy also.

As if all this pollen daubing weren't complicated enough!

I am really looking forward to seeing how delayed germination seedlings
compare with those that germinate the first year, as well as seedlings
from the same cross made different years.

<Several hybridizers have mentioned rather different results on the same
cross repeated from one year to another. Modern evolutionary thought
points out that the environment not only works on the entire plant to
select those with the greatest survivability, it also works on the plant
parts, in this case the pollen and the ova. A wet, cold season may allow
different pollen grains or ova to mature than those allowed to mature in
a less wet, warmer year, depending on the genes those gametes carry. In
fact, it may be that a cross made early in the season may produce
somewhat different results than the same cross made late in the season
if the weather has changed!

                   This has a number of implications. A cross make in
one part of the world may give different results from the same cross
made in another. A flower from the top of the stalk may give slightly
different results that a flower at the bottom. etc. etc.
