Calvin Lamborn, plant breeder

Calvin lamborn

It isn’t that people don’t want to know who bred their favourite fruit and vegetable varieties, it’s just that the story of those breeders is so seldom put before us. A tribute post from @culinarybreedingnetwork alerted me to the death of Calvin Lamborn. And who is he? Only the man who gave the world Sugar Snap peas, and many other wonderful peas.

Jim Myers, no slouch as a plant breeder himself, had this to say:

Calvin is the reason why we have snap peas as a part of our everyday cuisine in the U.S and in much of the world. Most people think that snap peas have always been part of our food culture, but before Calvin’s work, snap peas were only a very minor curiosity in the garden. When he went to work at Gallatin Valley Seed Company in Twin Falls Idaho as a young plant breeder, he was given the problem of “straightening out” edible podded snow peas. He wondered what would happen if he crossed a spontaneously occurring trait for thick pod walls in the old shelling pea ‘Dark Skin Perfection’ with ‘Mammoth Melting Sugar’ snow pea. The result was completely unexpected; it did straighten the pods, but it was a completely different crop. The first variety from those breeding efforts was ‘Sugar Snap’ pea and he is responsible for releasing most of the snap pea varieties that we enjoy today. Equally critical, snap peas would remain a minor curiosity today if not for his continuous and tireless promotion of the crop. What I have learned from Calvin is that if you are trying to introduce a new crop, it is not enough to just breed improved versions. One must get it in front of the world to let others understand the novelty and benefits that the crop can bring.

Edible Manhattan has featured Calvin Lamborn, as has Civil Eats — and if you’re really keen, there’s a three-part webinar on YouTube in which Jim Myers talks about “Putting the snap back in snap peas.”

I hope Culinary Breeding Network doesn’t mind me using their image.

Composite provenancing for crops too?

I completely missed an interesting blog post by Prof. Andy Lowe of the University of Adelaide when it came out a couple of years ago. “Local is not always best” updates a paper in a previous article ((Lowe AJ (2010) Composite provenancing of seed for restoration: progressing the ‘local is best’ paradigm for seed sourcing. In: The State of Australia’s Birds 2009: Restoring Woodland Habitats for Birds. (Eds David Paton and James O’Conner). Supplement to Wingspan 20(1) pp 16-17.)) on where you should get your seeds from for habitat restoration projects. In summary, the answer is: not all from one, nearby place.

To simulate the natural mixing of genes during a restoration programme, it would be necessary to restore populations using a mixture of material sampled at different distances from the focal site, a practise defined as composite provenancing. This ‘composite provenance’ would be predominantly composed of locally sourced material, taken from genetically healthy stock, but would also incorporate local and ecogeographically matched sources. In addition, a smaller proportion of material, depending on the natural gene flow dynamics of the focal species (but usually somewhere between 10 and 30%), should be comprised of material from much further a field.

Though Prof. Lowe deals with wild species in his paper and blog post, I think “composite provenancing” is also be relevant for crops. Sometimes, too much is made of “genetic integrity” and localism.
