There are many other examples of plants that have either evolved/mutated or been cross-bred by humans.  My father cross-bred a hard pear tree which pears were primarily used for canning with a soft eating pear and got something that was soft enough to eat and firm enough to can. 4951

Cross breeding is different than GMO, no? One can happen naturally, the other not so much.

@TXSunDvl:  As far as I know, there are three basic types of propagation of plant changes at a pretty base level:1. When a plant naturally mutates and produces desirable properties, save the seeds to grow more mutated plants.2. Cross-pollentation, which can occur naturally or with the help of humans.3. Grafting a small branch/tissue of one variety onto the base/trunk of a young different variety.  The graft must be applied to the base plant when it is young or it will already have established its natural properties.
 
 
All three are simple forms of genetic changes, but at its most simplest process.  My father used grafting on his pear trees.  Of course, these methods are limited to reasonably similar plants. Cross pollinating or grafting an orange tree and an apple tree most likely will not work. Pollen would not be be accepted by the female receptors, and grafts would likely be rejected by the base plant. 4951

@TXSunDvl: not really, it just expedites the process.

I disagree. What Monsanto has done to corn and soybeans are NOT natural. I hate what they have done to our foods. Want to know why our cancer rates are increasing so badly? Look at Monsanto. Grafting is something entirely different, and while it changes the outcome of the fruit or vegetable, it in no way is genetically modifying the plant. If you you trier to graft two plants and nature rejected that graft, that is nature's way of saying it's not natural. 4951

@ExBlue: you'd find something else compatible and then work on it that way. It's a slow process and it's been around for a long time in other industries. No one knows why our cancer rates are increasing, we're exposed to a lot of things that people don't think much about.

My father also reminded people not to plant hot peppers of any type near bell peppers.  Natural pollination from the bell peppers reduced the heat of the hot peppers,  but the bell peppers didn't get hotter.  So it only worked one way. 4951

@ExBlue:  Grafting DOES change the base plant by changing its DNA.  The DNA of each plant mingle and create different traits.  The resulting fruit/seed/vegetable, if planted, will have the modified DNA.Cross pollination affects the fruit/seed/vegetable but not the base tree. HOWEVER, the SEEDS that result from the cross pollination have modified DNA.  If you plant those seeds, the resulting plant/tree will have slightly different DNA from the pollenation donor and the pollen recpient.Nature and humans have been practicing genetic modifications forever (mostly by trial and error).  While I applaud Monsanto and others for making crops more disease-resistent,  the majority of their work boils down to profit, not health.  Farmers want disease and drought resitant plants that produce at a higher yield per acre.  If Monsanto can provide seeds for that, farmers pay higher prices for those seeds, and Monsanto makes more money.  We do not yet know if there are any ill effects from GMO plantsWhen we travel to NE Louisiana, it's common to see fields, each growing different plants with signs stating what variety is being grown.  Farmers know the variety they planted so I assume these are either test plants, or plants grown for their seed for Monsanto or others.
 
 
Added:  There are many different techniques for grafting.  One technique, say between a plant/tree with white flowers and another similar plant/tree with pink flowers, may result in branches with white flowers and other branches with pink flowers (which I assume also applies to any fruit it may grow).  The fruit on each branch could also be different. 4951

Cross pollination and plant grafting does not kill off our honey bees, but Glyphosate does! 4951

@ExBlue:
 
Recent studies have proven otherwise.
 
But there are some insecticides that are having a real adverse affect on the bed population.
 
Neonicotinoids are the real bad ones for bees.
This is a whole family of insecticides commonly used today that appear to be causing colony collapse disorder.

Also, they are not that far apart.
 
IMO the GMO hype is a lot like the gluten hype.
99.8% not an issue.
Cross breeding and hybrid's have had issues in the past also.
 
Example, the Lenape potato and Magnum Bonum potato.

Honeybees love big old oaks. Those go at a premium on the timber market and there's just not a whole lot of old growth pristine forest left. When they opt to hive in homes instead that's not good for all involved. 4951
