Re: REB: fall cyclic vs other (was seedling help on photos group)


[so folks trying to find info in the archives are more likely to find the discussion, I've moved my comments there as well as photos]

Too soon in attempted rebloom crosses to say for sure, but so far, rebloom seems to be acting like a full recessive trait (i.e., 1/36 fall cycle from two half "summer" rebloom parents). Climate interaction and multiple genetic factors makes it hard to interpret data, but easy enough to figure out what I want to change.

I'm still not totally convinced that fall cycle and "summer" (i.e. jul/aug in my climate) bloom are separate genes. With only maiden bloom, it's too soon to tell how many/if any of the late fall bloom this year is really rebloom, much less whether it's cycle or summer.

However, if your theory holds for my climate, Chuck, based on leaf count, it looks like they will all be late cycle.

If they are separate genes, most/all of the "summer" bloomers here also have cycle rebloom genes.

But am hoping that whatever other factors are operating in plants that <can> bloom in July and Aug in California have a chance of combining with plants carrying Jul/Aug genes here to produce plants that will thrive in my growing conditions and at least bloom by Sept. I'm hoping to combine traits of my plants that thrive in summer high humidity and erratic rainfall with those of cultivars that bloom in CA summer heat.

May not be possible, but I figure it's worth a try.

So far, the only west coast summer bloomers that have rebloomed here are FEED BACK and GOLDEN IMMORTAL. At least those are the only two I can think of. MARTY RICHARDS is alive, but doesn't rebloom. MARIPOSA AUTUMN is a strong growing, reliable, fairly early cycle rebloomer here.

Chuck replied:
<Fall Cyclic maturity seems to act like a dominant factor, so no need to cross it with an other Fall cyclic rebloomer. Just a plant with fast growth and low "plant Maturity" leaf count.>

I said:
<To get away from all this late cycle rebloom here, for next year's
rebloom crosses, I hope to mix the late cycle genes from a few things
exclusively with west coast "summer" bloomers to see if that will get
the right mixture of rebloom genes to at least get earlier fall bloom.>
