Re: HIPS: HYB: chromosome counts

From: "Donald Eaves" <donald@eastland.net>

Questions here.  If 48 is the normal chromosone count and PURISSIMA has
47 but shows up in several pedigrees, LADY MOHR has 45 and is known to
have very limited fertility, COPPER LUSTRE has 49 - any fertility here?  Is
there a guideline for using a count such as this to increase the chances
setting seeds?  Can you match equal counts and expect an increased number
of takes?  If the count is only off plus or minus one chromosone, is there
a good likelihood of setting seeds?  Do your chances decrease to very
as you move the parent's count away from each other?

order of
the day.  Can't remember that during the winter months before.  Melt some
of that stuff, Borer, and send it to West Texas.
