From what I read on various blogs and comment streams, there is way too much angst out there about GMO crops. Too much angst because every significant panel of scientists that has reviewed this technology has concluded that it is as safe as any other domesticated food crop. Too much angst because the reality is that only a small number of crop species will ever be genetically engineered for commercial use. There are four main reasons why this is the case:
1. Brand protectionism
2. Unfavorable economics
3. Other ways to achieve the same goals, and
4. Anti-GMO activism

It’s an exciting time in genetic engineering! I’ve long been bored by the simplicity of our contemporary transgenic crops and the single-minded focus on agronomic traits. Dropping in an herbicide or pest resistance gene is good for the environment and the farmer, but it doesn’t visibly benefit the consumer very much and just doesn’t impress me technically. Now, Monsanto and Pioneer’s new soybean varieties are heralding a new era of more sophisticated metabolic engineering

“With over 80% of the corn grown in the US genetically modified, and biotechnology companies phasing out non-GMO corn seed varieties, American farmers have fewer choices for finding non-GMO seeds to grow.
As a result of this narrowing of farmer choice, a new initiative was launched in 2009 by Practical Farmers of Iowa (PFI) to address the problem. The US Testing Network (USTN) aims to develop and introduce new non-GMO corn hybrids in the

I’ve been meaning to tell this story for some time. It’s a good example of how not all biotechnology is genetic engineering.
Traditional Breeding
In trad breeding, the breeder/gardener simply crosses two parents that show great (and complementary) traits, grows up the offspring, selects the best and repeats. It’s effective, slow, labor intensive and limited by the perception of the breeder. Most traits are also very heavily impacted by the environment, so each new genotype must be grown in multiple locations +/or multiple years to make sure the recorded phenotype is due to the genetics (not the environment) of the individual. Most of our crops were domesticated and refined this way (quite a success!). Modern breeding has additionally been refined by the development of various statistical techniques and crossing schemes that make the whole process more efficient.
Back in 1995, I was party to some discussions about whether about-to-be-released GMO crops should be labeled at the consumer level. It was clear that a failure to do so would look to some like a conspiracy, but we also realized that it would be far too expensive to track the great rivers of grain well enough to be able to label everything accurately. Practicality won the day and GMO foods were never labeled. 15 years later this decision is still being needlessly debated.
