Richard wrote: I don't think the terminator technology has claimed to increase productivity. It is intended to protect the originator of a hybrid by not allowing the plant to produce viable seed. In other words, it extends any plant patent indefinitely if it doesn't obviate the need for a patent in the first place. Richard, my writing was sloppy. One of the arguments I hear in support of terminator technology runs along the lines of a) hybrids are more productive than open pollinated varieties and hyrids offer the best chance of feeding the growing number of people on the planet, b) the "best" way to provide incentives for the continuing and future creation of "needed" hybrids is to render the seed sterile so the patent holder is protected against loss of revenue downstream, c) because of a) and b) it therefore follows that terminator technology is the only way to produce better hybrids needed to feed the world. And that's twisted, specious and crazy "logic" in my book. Catharine
