I read a little bit about pepper breeding. As I understand it there is only one gene (pun-1) controlling heat level. Cross breeding with sweet pepper should be easy. I wonder how to find heatless plants when growing out F1 hybrids. If there is a chance to find them already at flowering stage I could cull all plants with heat and breed only with sweet plants.
Any prctical advice?

Can anyone comment on whether the buds or flower petals of hot peppers have any zing to them? (Just an idea, I don't know!). If true, you could use a taste test to screen at that stage.

It is my understanding that one gene controls heat vs. no heat, but many genes control heat level in the hot ones.
I know of no way to tell hot from no hot without tasting the fruit. And while it is very simple to taste one fruit after another, looking for plants with no heat fruit, After tasting a hot one, you might need to wait a few hours before tasting the next one. And some fruit taste sweet at first, but heat builds up after swallowing or spitting. However, in an F2 population, 1/4 of them should be no heat, So you wouldn't have to taste a lot of them, unless you wanted to test for different flavores in the non-heat plants. And I think flavors woulf vary in the non-heat plants.

If you want a sweet version of your variety, the good way may be recurrent backcrossing. The bad news is that sweet is recessive, so you may be forced to do :
Y1
- Cross Canoncito x sweet
Y2
- Grow F1 and ensure self pollination (or interpollination of F1)
Y3
- Grow F2
- Hand pollinate F2 with Canoncito
- Taste for sweetness and then select seeds from hand pollinated sweet individuals
(or maybe taste the first fruit of each F2 and then cross polinate sweet x canoncito)
Repeat Y2 and Y3 a number of times

You could also just wait for Wild Garden Seeds to offer a sweet selection.
They received the seeds in 2014 and offered them in 2015. Beginning in 2016, they wrote this: "This year we made dozens of selections from the diversity - ranges of heat and sweetness, wall thickness and smoothness, upright versus creeping habit."
Their 2019 catalog hasn't appeared yet. Will it offer some sweet Canoncitos?
