I like the "perennial" trait. I would still save some seed in case the crop is lost due to other causes (hard freeze or extreme heat). The current hybrids still seem to expire in a number of years, but that is much better than truly annual grains which Must be replanted each year.
Definitely something to watch closely as the hybrid continues to be cross bred. Higher yields would help.
I wonder about the need for fertilizer on multi-year crops. Given the unavailability of chemical soil amendments, some method must be found to renew the soil without plowing in the perennial crops.
Not needing to plow, till and replant would be a major labor saving, not to mention the lower fuel costs.
