PINRANG/JAKARTA, Oct. 15, 2012 (Reuters) — Nurhaedah, a vivacious Indonesian cocoa trader, shakes her head in disappointment as she sifts through a pile of blackened, shrivelled beans. Yet another crop from "Frankentrees": weak, misshapen cocoa trees toppling under their own weight.
A $350-million campaign to boost cocoa yields in Indonesia, the world's third largest producer of the commodity, is turning sour as farmers send streams of poor-quality beans plucked from the defective trees to a collecting centre Nurhaedah runs.
"Farmers are complaining the beans are so small they look like roasted peanuts," said Nurhaedah, as her deft fingers sought out the bigger beans whose size indicated better quality.
"I don't think anyone has told us what went wrong. Many trees have fallen down and when you pull them up, it's obvious they don't have taproots."
Plant cloning has been used for hundreds (if not thousands) of years very successfully. You've never taken a cutting from a plant and started another? That's a clone.

"There were cases when nursery workers didn't properly treat the roots. I don't want to blame anyone, but it may also be due to our fault for not providing clear instruction to farmers," said ICCRI research head Soetanto Abdoellah.

. What do they expect? This is akin to breeding runts. You don't breed a racing horse because it's on it's feet and singing "A horse is a horse, of course, of course!" as soon as it slips outta mummy.
Seedlings from the new clone take only three years to produce cocoa pods, versus four years for non-cloned varieties.
Somatic embryogenesis is a process where a plant or embryo is derived from a single somatic cell or group of somatic cells. Somatic embryos are formed from plant cells that are not normally involved in the development of embryos, i.e. ordinary plant tissue. No endosperm or seed coat is formed around a somatic embryo.
Obviously there is a difference here between a cutting and this technique.

The technique called somatic embryogenesis, or SE, was invented to produce high-yielding, disease-resistant seeds.
For example. You could say that in vitro fertilisation is the same as getting pregnant the old fashioned way, the underlying principles are the same but the differences in the process bring their own possible complications.

Not really. When you take a cutting you use cells which are not used in the development of embryos (seedlings). Instead, ordinary plant tissue is used. See the "i.e. ordinary plant tissue" part of your quote? It's the same thing.
The result of a cutting and the result of "somatic cloning" is the same. You get a plant genetically identical to the source plant. The advantage of somatic cloning is that you can get a lot more clones because you are only using a few cells for each start.

edit on 10/15/2012 by Phage because: (no reason given)
The most common cloning method, known as "somatic cell nuclear transfer" or simply "nuclear transfer," requires two kinds of cell. One is a somatic cell, which is collected from the animal that is to be cloned (known as the "genetic donor"). A somatic cell is any cell other than a sperm cell or egg cell, and contains the complete DNA, or genetic blueprint, of the animal it came from. For cloning purposes, somatic cells are typically obtained by a routine skin biopsy performed by a veterinarian.
The other kind of cell required for cloning is an egg cell, which is collected from a female of the same species (known as the "egg donor"). In the lab, a scientist extracts and discards the nucleus of the egg cell, which is the part of the cell that contains the egg donor's genes. The scientist then inserts the somatic cell from the genetic donor into the egg and "fuses" the two with electricity. The resulting fused egg contains the genetic donor's DNA.
But someone taking a cutting from someone else, and propagating a full plant, is not the same as this
No. It is completely different. One is simple somatic cell cloning (also know as micropropagation) the other is somatic cell nuclear transfer.
I do understand we're referring to plants and not animals. But it is the same in principle.
Actually, a lot of "top notch" gardeners do do it. But the requirements are a little more sophisticated than your average gardener can manage. Of course, your average gardener isn't trying to produce thousands of clones or plants that are difficult to propagate otherwise.
Grafting, cloning, or what your average top notch gardener does, is not the same as this.
It is not the same technique and the plants which result are genetically identical to the source plant. If there is a problem it is in the source plant or the way the plants are raised.
And in my opinion, a sure sign that if we cannot even create stable plants using this technique, we should stay the heck away from Dolly.

Exactly. Banana Tree's are all clones, as Banana tree's are non-fertile hybrids between two different species. And that Hybridization produces those delicious banana's
