breeding Annuum-Pubescens hybrids...

The seeds are not viable only in rare cases , whereas most of the cases will be normal germination , highly fertile or partially viable.
 
Interesting! I always thought (from the literature) that they couldn't cross with other Capsicum varieties.
 
Using... "a plant of a bridging Capsicum species selected from the group consisting of: C. chinense, C. baccatum, C. praetermissum, and C. eximium to form a C. annuum hybrid, and crossing one or more progeny from the first cross with a C. pubescens plant to form the hybrid between C. annuum and C. pubescens."
That's how they did it.
 
Claims:
1. A method of producing an interspecific F1 hybrid pepper plant comprising the steps of:(a) pollinating a male sterile flower of a C. annuum parent selected from a C. annuum plant or a C. annuum hybrid with pollen from a C. pubescens plant or C. pubescens hybrid to form a pollinated flower;(b) following (a), treating the pollinated flower with an auxin compound;(c) growing the C. annuum parent until the pollinated flower develops into a fruit bearing a seed;(d) harvesting the fruit bearing a seed that develops from the pollinated flower; and(e) rescuing embryonic tissue from the seed of the fruit to produce an interspecific F1 hybrid pepper plant.

"We made plants have sex, and gave them plant reproductive hormones that were discovered in 1928.  We can haz patent nao?"
 
Anybody familiar enough with what they've done to say what exactly they did that the patent covers?
 
isn't the whole definition of species that they can't breed with each other?
Or they can but their offspring will be infertile (mules, ligers, etc)?

Species can be defined as separate if theyre reproductively OR geographically isolated.

"Species" is just a word that humans made up.  It works for the obvious cases, but not so much for the gray areas.  Shake a bunch of DNA together and see if it mixes.  If yes, "species".  But what if only 99% mixes?
 
There's some common example of bird species.  A, B, C.
 
A can breed with B.  A and B must be the same species, right?
B can breed with C.  B and C must be the same species, right?
A can't breed with C.
 
Also, there have been many cases of fertile mules, and female ligers are usually fertile.

There was an earlier patent application that pre-dates that patent cited back in 2011:

I'll look an article that was shared in my Facebook group saying that chacoense varieties have a very good chance of accepting pollen from a pubescens. It's based on scientific research.

I've read about c. chaocoense accepting polllen from c. pubescens. The cross still runs into fertility problems after accepting the pollen though. The article I read was unsure of the cause and a little inconclusive.

Yeah I know what you mean. There's yet to be any successful cross with these 2 soecies. The article does say that if suitable conditions are given there's a higher chance for it to be successful. Probably needs more attempts in different Conditions. Idk, I do have a couple of pubes and about 4 different chacoense, we'll see LOL...

I'm overwintering c. chaocoenses and have various pube seedlings. I think we read the same article. I'll be trying it but not putting much hope into it.

Since it's some 9 months later now -- do you have any updates? I'd assume not, if you had only tiny pube seedlings back then, but still... I ask because I'm extremely intrigued. 
 
I know this is an old thread recently resurrected, but.......
 
From what I read the way they got plants out of this cross was through embryo rescue. It is a technique used to get plants from crosses that would otherwise be inviable. basically you cut the embryonic plant out of the immature fruit (pepper in this case) and then put it into a petri dish with a nutrient medium that allows the embryo to continue to develop into a plant,
 
I have used this techniques for euphorbia species, and in my experience it is a numbers game.
 
I had about 2% of my embryos grow into plants. but it is really cool when they do, you really feel invested and like you are somehow its "parent"
 
I know, thats weird, but I'm willing to bet more than one person reading this is a plant weirdo too  :)
