You must be eating different Manzanos or Rocoto than I grow. There are 3 kinds of Caspacin. Manzanos/Rocotos have all three. Different forms hit different receptors in your mouth. Usually they seem hotter than they are compared to habs etc. They are far from being a mild or a sweet pepper. Some are at least Habanero hot. They taste totally different than any other pepper. Very fruity,nothing like a bell pepper. Fresh off the plant they are very crunchy with a slow build up of heat. In Peru they seed them and then boil them before using them to cook with to get rid of some of the heat. Boiling does take away some of the heat but I've never had one that was anywhere near a bell in mildness. I grow Yellow,Orange,brown , peach , white and red rocotos from Peru seed stock and Manzanos from Mexican and U.S. grown commercial pods or nursery plants. C. Pubescens won't cross with most other pepper varieties-see link above. Here is a link that might be useful:

type in Pepper Cross Pollination in the search bar. Seems to be a big topic. Enjoy

Speaking of cross pollination, my Sannams and Pusa Jwala have got mixed up and are groing like crazy. First flower buds have set in. I am sure that I am going to have a mixed breed of hot peppers. Thank God, I am not going to use the resulting seeds next year. I might move to Texas and will try some exotic varieties and my Nagas. NJA

Hi Paul, I am from China and not aware of all varieties you mentioned, such as yellow banana bell. But here is something you may want to know: 1, Species would be a different meaning from varieties, crossing usually happened by chance between the same species but differents varieties. Different species MAY have crossed and set fruit, give you seeds, lower chance. 2, A cross may hightly lead to RED FRUIT on mature, for the yellow, white and brown color of fruit is ALLELE LOSS. But RED one is INTEGRITY. 3, Spicie from parents MAY hightly lead to even, but there is many content making the pepper taste hot in fact. So a hybrid variety could be more spicie than any parent if the parents are complementary on these content. 4 (original selection), To remain and prevent from fruits changing: 1) Make sure the varieties you have grown is NOT HYBRID seeds. Hybrid seeds will derive greatly on the F2 generation. 2) You have already lost the original seeds and need to buy them again. 3) Plant new seeds. When the pepper is blooming, remove the flowers and keep the bud. Put pollen separation net on EACH varieties. Mark the bud on anthocaulus by color or wire. Remove the nets when 5 to 20 fruit set on each plant as needed. Wait for the marked fruits mature. Collect fruits WITH MARK for EACH variety, then original seeds have remained. Tips: a) If a different type plant was found before blooming on one variety, remove it. b) Do step 4 every one or two years, and keeps the seeds on last two generations. If a selection failed, plant the last original generation and keep selection. c) A normal original selection needs at least 30 plants for each varieties.
