Despite the usual hyperbole about the promise of GM disease resistant crops, hardly any have been commercialised anywhere in the world and some of the biggest claims to success have been exposed as false. Non-GM plant breeding, on the other hand, has achieved success after success. Here are some of the non-GM successes.

Field trials find organic bean varieties sustainable, high-yielding and disease-resistant (April 2020)
Plant breeders at the University of California, Davis, are releasing six new varieties of organic beans. Field trials found that the new varieties produced high yields, and were resistant to bean common mosaic virus (BCMV), a disease that prevents bean plants from maturing promptly and uniformly.

High yielding, multi-disease resistant, non-GM bean success in Rwanda (February 2010)
An excellent example of the success of traditional plant breeding practices - multi-disease resistant, very high yielding, no mention of GM and apparently freely distributed without IP ties. What would the GM lobby give for one good success story like this?

Researchers develop non-GM papaya resistant to ringspot virus (September 2011)
Despite claims that only GM could deliver this, researchers have developed a papaya resistant to ringspot virus through conventional breeding. The researchers comment, "Application of these results should lead to restoration of the papaya industry in virus-infested regions of the Philippines and worldwide." GM proponents have repeatedly promoted GM ringspot virus-resistant papayas as the only solution to the problem.
