Re: :HYB:Pod Vs Pollen Parent

<I asked a very prominent, and now deceased, hybridizer this question,"What percentage of traits are inherited from the pod parent vs. the pollen parent?"...

I would guess, based on my limited knowledge of genetics, that every iris has it's own personality. Each iris, I would imagine, pass different traits on different genes and some would pass the same but I'd venture out to guess no two varieites are the same, either. That seems to make sense to me. Until I know differently, I will guess that I'm correct in my thinking. I'm guessing the hybridizer you wrote to may very well have determined there to be no difference based on his choices for crosses.... hmmmmmmmm.........
Your quote of 70%-75% from pod parent could be right, i'd guess, depending again on parent iris... I was recently advised that the pod parent may be responsible for passing vigor on to the iris, so, only time and testing and further info from others will put a less hazy cloud (hopefully) over us :)
Selfing is the first thought that crossed my mind when uncertainty of fertility is the issue.
and, yes, Betty, any information and experiences of others is helpful and of intrest.

This is probably the case.  I have known hybridizers to recommend selfing a 
new and promising seedling to determine it's fertility.  Some have listed 
this trait or lack thereof in their introduction material.  I believe Ghio 
has made this a practice at times & maybe even Keith K.  Details as to the 
hybridizer giving this recommendation is foggy at this time.  I'm better at 
remembering the information than I am at remembering where I read or heard it.

In reference to T.B.s only, I will pass this on from personal experience: 
Several years ago, while preparing some articles on hybridizing, I wrote to 
several prominent hybridizers with a number of questions.  Unfortunately they 
were not always the same questions. I asked a very prominent, and now 
deceased, hybridizer this question, "What percentage of traits are inherited 
from the pod parent Vs the pollen parent?"  (I'd been told about 70%-75% came 
from the pod parent) 

He replied that there was no difference. In his opinion, you might as well 
mix up the seed from a cross & it's reverse and plant them all together as 
there was so little difference!  I respect those that have gone before and I 
have tremendous respect for this gentleman, but I have to question this 
answer.  

In my first year of making crosses, I had stumbled across something that, to 
me, blew this theory out of the water!  Only having one true rebloomer in my 
garden that spring, I made crosses with anything in my collection that was 
reported to have sporadic rebloom. I crossed HIGHLAND CHIEF & PEACH SPOT both 
ways.  It was probably the most interesting cross I've ever made.  All of the 
children with PS as the pod parent gave a max. of 4 buds, were kinda short, 
and all washed out.  I don't recall any being memorable except my first 
rebloomer that I nicknamed "Big Bertha."  A rather ugly thing with big 
blooms!  A white with a few flecks of purple, as were most of these 
seedlings.  All had very thin substance.

The reverse cross, with H.C. as the pod parent gave such a wide and varied 
group of children that I remember them still . . . an orange with triple 
sockets producing 9 buds . . . a yellow & white BRIDES HALO pattern, several 
nice plicatas . . . etc!  It was my first crop of seedlings & I fell in love 
with all from this cross.  It was years before I trashed them all. 

Other crosses with P. S. used as the pod parent (I used it a lot for 2 or 3 
years) did not necessarily give the same results.  I put pollen from Copper 
Mountain on it and got one yellow & brown ringed beauty (my eyes only) that 
was tall with lots of buds.  Form was older than accepted at the time.  It 
really drew the eye and I loved it.  I still have a seedling from P.S. X 
Vanity.  It gave some very interesting things, most with better form and bud 
count than P.S.  In none of these cases did I make the reverse crosses.  

I don't know if this contributes to the question asked, but maybe it will 
help.
