Dear group last sunday in Ann Arbor at the fall meeting of the
hybridizers group we had as our guest speaker Bill Zumbar very
entertaining and most informative. The following are some tidbits
hope you enjoy them
There are about 5 lines to go down for mini plants
venusta but about the F3 level you start to get bad things ?
shinning tot F1 then back cross you will get real small but a lot
less seed
dwarf grex lines
venusta hybrids
bitsy green
kifufurin forms (about 8) hard to set seed
saisho yamato siyu
catseye ? fertility
little Jim
kii himi (korean hosta) collected by Yinger Zumbar has 14 seedlings
To see if you have a true venusta the scape has a ridge at the base of
it that you can feel with your finger otherwise you have a hybrid
some people are thinking uzo-no-mai (sp) is a longissima hybrid but
its flower doesn't fit
white centered plants selfed will give you lethals but also streaked
plants
bill Zumbar dwarfing is a pod parent dominant size and presence
bill Zumbar has one grex of green plants whose pollen however dictate a
smaller plant (his only found exception to above)
he feels above 75 is hazardous to hybridizing
white flower is recessive
flower size is maternal and he now has a new plant that has reduced the
flower size by 1/3 H Royal Vessel soon to be released
selfing always reduces the plant size
there are two excellent test to see if the plant is to remain small
1 move the plant to different locations
2 divide the plant and see if the plant multiples and stays the
same size
On a lighter note he would like to see judges judge sections 7-12
first so they are fresh and observant on new seedlings and sports.
If your group needs a speaker bill does a very fine job slides and
handouts
finally recently he has researched the literature and found out that
calcium via gypsum or fish bones (fish meal) is a necessary
component to the health of the hybridizing plant both flowering and
pollen However pH of the ground (it raises it) must be monitored
very closely that was about all got to run later doug
