- Temperature increase reduces global yields of major crops in four independent estimates. “Without CO2 fertilization, effective adaptation, and genetic improvement, each degree-Celsius increase in global mean temperature would, on average, reduce global yields of wheat by 6.0%, rice by 3.2%, maize by 7.4%, and soybean by 3.1%.”
Breeding tomorrow’s heirlooms
Interesting article in Modern Farmer, on Why We Need to Revitalize Organic Seed Farming. They rounded up the usual suspects, who offer the expected explanations, none of which detracts from the importance of what some breeders are doing.
“The heirloom boom of the nineties helped people see the value of preserving seed, but they don’t understand that it can get even better,” says Selman. “Public plant breeders are creating varieties that are more resilient and more appropriate for the future.”
Lane Selman talked to me about her work with the Culinary Breeding Network for Eat This Podcast.

Caribbean genebanks in the firing line
Sin maíz no hay país
Town by town, I looked for these seeds, studying where they might be located. I started driving to many states in Mexico trying to find them, but there were none. It was so disappointing. One by one, I had people telling me that their grandparents planted them, but not anymore, and they lost the seeds awhile ago… I visited a very old lady who recalled planting them herself, but there was a big frost many years ago that caused her to lose all her seeds. After that, she started buying tortillas.
That’s Rafael Mier on maize in Mexico. But in how many places around the world, and for how many crops, is something similar happening? Perhaps the worst thing about genetic erosion is that we don’t know what we don’t know. But then again, maybe it doesn’t matter, if there are people out there like Rafael doing something about it.
…he was eventually able to find the popcorn seed he needed from a farmer in Mexico state—after planting, it’ll be part of his 2017 personal harvest as well as the first harvest of this variety in 60 years, Mier believes.
Mier believes.
