I think the heritage of your crosses might be a bit more complicated than you think. In general, the crosses from chinense mother x annuum father are usually not viable, are dwarfed, or show a virus-like syndrome (the other direction actually works with low efficiency). And then, all F1 crosses...
The earliest mention of Peruviano Arancio I could find so far is in the Semillas Las Palmas catalog where it said in 2011 "New in 2010" (https://web.archive.org/web/20111010083254/http://www.semillas.de/cgi-bin/shop/shop.cgi?shop=&product=Chilisamen%20NP&cart_id=5124171.7990). Seeds of Jamy were...
The correct calculation results in 46.65 % nitrogen in urea (14.01 g/mol (N) * 2 (atoms N in urea) / 60.06 g/mol (urea)) and 16.53 % N in DEF (1.09 kg/L (density DEF) * 32.5 % (urea in DEF) * 46.65 % (N in urea)). And the paragraph about the dangers of the deionized water in DEF is almost comical...
I have searched a bit more and found this old seed catalog from 2016 from the Azienda Agricola Sperimentale Stuard, the place where Dr. Maria Dadomo selected the Jamy variety: http://www.stuard.it/wp-content/uploads/Catalogo-2016-Peperoncini.pdf. It states that Jamy is "a selection made by Dr...
Pure agricultural urea will almost certainly be much cheaper. It is used in much higher quantities, doesn't have to be dissolved and bottled, and doesn't have to be that pure. Pure NH3 is actually 82 % pure nitrogen, you are probably talking about ammonia solutions (just multiply that percentage...
If the variegation were indeed inherited maternally, it would appear immediately in all F1 from a variegated mother. The pollen donor would not pass on this trait at all.
Germination efficiency is not a property of the variety but critically depends on the seed storage conditions. Pepper seeds lose viability really fast when stored without protection from heat and humidity. Optimal conditions would be heat sealed with drying agent and oxygen absorber in the...
This is from a Turkish scientific publication (left: germination speed (çimlenme hızı), right: germination percentage (çimlenme oranı)):
They tested 10 different Capsicum chinense varieties in a ±1 °C incubator.
