Trippaul Threat (PdN x BMJ) Community Grow

This is a dedicated grow log for Tristen's awesome cross, which I
have been growing out since 2014.  I'll start with a bit of history and
some photos documenting what's happened so far.
 
In January of 2014, Tristen (Trippa) sent me a little care package of seeds.
In the package were two generations of a cross he had made, which he just 
called 'Mystery Cross, F1' and 'Mystery Cross, F2'.  
 
Here's Trippa's Mystery Cross seedlings in February of 2014:

 

 
Both generations showing the purple foliage characteristic since the beginning.
 
Up close look at Trippa's Mystery Crosses, F1 and F2.  Both culled to a single
plant after the photo taken, so I only had one plant of each generation:

I planted F6 Whites and Purples and F4 Whites, I got 50% germination on the F6 Purple and F4 White.  I got 1/6 on the F6 White about a 17% germination rate there. Most people were having troubles with them.  Best of luck.
 
Edited to add: Just noticed the F6 Purple has another seed coming up, that will make 4/6, so somewhere around 67% germination rate for that one.
 
Edit to correct & symbol to % in the above sentence.

Welp I can't seem to get lucky with these seeds. I've tried two times and both times I had terrible germ rates. The few that did germ were helmet heads. I'm gonna try one more time I think.

Sounds good considering All things, Craig.
 
At least you have some of each going forward.
 
I hope they go bonkers for you!

Don't know if I've had any sprouts quite as hairy as the pdn x bmj

They ain't no weak plants that for sure! Vigorous and strong [emoji123] is the name of the PDN BMJ game!

Been taking off bottom leaves to get some airflow to the soil. Been having some fungus gnats.

Here's one from the top shelf, I think the LEDs work juat fine. If anything I had them too close for a while.

Just WOW, Andy! Those look superb!  How many are
you going to grow out?  If you are growing upwards
of 700 plants, will you have room for them all?\
 
So beautiful...

Interesting variation on the color path the F7 pods are taking.

The F7#4 pods are shading from dark purple to dark green,
then lime green. After that, they turn to light cream color or white,
from the stem end toward the tip.

Last season, one of my F5 plants produced pods the same way.
This season, looks like one out of four F7 is following that path. The
foliage on this plant is lighter and greener than the other three.

The traditional path is for dark purple, then gradually shading to lighter
violet and finally white. Two of the F7 are definitely following this path.
Not sure about the fourth plant, yet. This is from F7#1:

Looking forward to podding time for this season
to see if this is true throughout the grow.

Wow! That's really neat! I believe both of mine last year followed the "usual" path....sans green. Very interesting that it took so long to show up.

 

[BDASPNY]

not as impressive as the plants above but they're trying!
 

 

 

[PaulG]

No need to apologize for those, Scott, they look
great. Nice color and very healthy looking! I think
you will find these to be very robust plants.

thank you.
 
I sure hope so they're def an interesting one to grow.

 

[PaulG]

thank you.

Here is a look at a couple of plants that hooked
On Jan. 10th and 11th.

those look great! amazing growth in a short time during the winter.

Groovin' right along, Paul! Wow! Those look healthy and happy! Vigorous growers! Flowers galore! And BIG! Those will be fruitful!

Hey, Adam, thanks, brother!

I suspect those will hit 5 - 6 feet tall this summer
barring any catastrophe! With nice, plump pods!

Interesting development in my F7 grow. Three
out of four plants are making pods that are violet:

Only one throwing white pods is F7#4. Also the
largest of the four plants, and setting pods right along:

Really looking forward to seeing how the rest of the world
does in this regard. Same thing happened in my F6 grow.
Three out of four plants from white pod seed threw violet
pods. This years seeds came from the one plant that threw
the white pods.

That would seem to indicate the violet shading is
the dominant color, and the white the rarity.
Especially hoping folk with lots of plants like John
and Andy will be able to share their observations.

[SIZE=10.5pt]Curious Paul, did you neuter and cross-pollinate with pollen from the same plant?  If so, then if the white were the result of a recessive allele, there would be only the white r allele and no dominant allele present in the genome to carry the D color forward.  The 75%/25% numbers do match what one would expect if an rr was pollinated by an DD though. Thing is though, one wouldn't select a DD to pair with because it would be showing the wrong color. One would select only an rr because only that would be white.  That makes me think unless there were an accidental pollination, this isn't a matter - or isn't only a matter - of a recessive allele.[/SIZE]
 
[SIZE=10.5pt]My best guess is that the white color is not controlled by a single genetic locus, so it's not a simple monohybrid cross, [/SIZE]but is being influenced by at least one other additional locus that needs to be selected for and stabilized. I believe white color requires 3 mutations to be present so perhaps they appear at multiple locations.

still growing, im hardening them off with the rest of my peppers. im hoping they take off with some real sunlight.

That's a nice trio of starts, Scott.
Some sun should really kick them into
high gear.

I wrote a long response to this yesterday, and then
when I tried to post it, the browser jumped to the THP
home page again  
 
In short, I hope that this large grow out of Tristen's
cross this season will shed some light on this. You
obviously know a lot more about this than I, CD!

thanks, I was hoping for 6 plants to grow but these are the only ones to make it this far.
 
 
any idea how hot this will be? a ballpark range.
