pepper fruits from cross pollination

6 years ago

last modified: 6 years ago

simple question: when cross pollination occurs, whether by chance or intentionally, between pepper species, do the resulting fruits themselves bare characteristics of the cross pollination or are they perfectly normal looking fruits of the "host" variety buy containing seeds which will grow to give plants that will then have fruits with a mix of the two parent species? also if thats the case, would all the seeds in one cross pollinated fruit give the same results or are they all unique in their "blend" of the two parent species?

reason im asking about fruit appearance is that im growing several pepper species in my container garder and some, such as my sweet yellow banana bell are turning up red and spicier than expected while growing next to a birds eye pepper tree. also an orange bell pepper plant gave fruits that are smaller and crooked in shape a little like the habanero close by.

ive included a picture of some of my peppers: the yellow banana bell that turned red, one banana bell that grew upwards and my jhabanero and two birds eye peppers. i didnt have any of the orange bell pepper on hand.

so?

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.

Fruits from the parent plant will not show traits of a pepper it was crossed with, those won't show up until/unless you grow out seeds from the fruit that was cross pollinated.

Can Hot Peppers cross pollinate Sweet Peppers?

Seeds produce no capsaicinoids (the stuff that make peppers hot). The only reason that they are hot is due to their close proximity to the placenta, they absorb some of the capsaicin. Capsaicin is produced in the placental tissue, usually concentrated where the ribs meet the wall. When people remove the seeds, they also tend to remove this material which leads to the false presumption that the seeds are the cause of the heat. The placental tissue only contains maternal tissue. The same as the pepper walls, etc. The reason people clean out the seeds is that 1) they are bitter 2) they are not fun to chew 3) they are not fun to look at Sweet peppers also tend to be easier to clean that hot peppers, due to the size (sweet tend to be larger) and the danger of handling them. They tend to have more pronounced placental tissue (once again due to fruit size). This tissue is rubbery when consumed and contains no taste benefits. In hot peppers, it is beneficial to keep it as that is where the capsacinoids are produced.

Well, I think they call hot tomatoes, "salsa", and you can make peach, mango and strawberry salsa also. The fruit salsa's taste great with some balsamic vinegar along with the peppers for that kick! All you need is a bowl, a knife, and a spoon to mix it all up! Have fun! Suzi

nardello pepper hot! cross pollination, ?
Q

Cross pollination affects only the seeds not the fruit itself of the current crop. Any crossing will show up the following year when those seeds are planted. Sure it is possible that you got some seed that had been crossed - especially from SeedSavers - but every effort is made by most commercial seed growers to prevent crossing. Many seed companies get most of their seeds from the same groups of growers so a crossed seed now and then in a packet isn't all that rare. But there are first class vendors as well as second and third and even fourth class vendors so it pays to use the better ones. Check out Baker Creek for Nardello peppers. http://www.rareseeds.com/jimmy-nardello-italian-pepper/ Dave

Concur; Be aware the Sweet Banana and all the banana types are red when ripe.

Also when picking ripe peppers, the seeds are second generation, a sweet pepper crossed with a hot pepper will not have any changes in the pod BUT The fully developed seeds may be hot.
