Preserving the canon of taste
Fascinating article in Aeon magazine by Jill Neimark, exploring the role of specific, older varieties in the experience of taste. I won’t steal her thunder here, just urge you to read it. I will, however, cavil at one statement:
All commercial apples, including Granny Smiths, have been hybridised to a sugary monotone.
That’s simply not true, unless hybridised means something else in Georgia.
If they’re called Granny Smith, their genetics should be the same. If they taste dreadful from the supermarket, and astonishing picked up from a roadside stand “by a white-frame house on a curving, shady lane by Lake Allatoona,” that’s the result of nurture, not nature.
But please ignore my quibbles — and I have others — unless you agree that sometimes accuracy matters.
Brainfood: Apple diversity, Wheat diversity, Wild lettuce diversity, Picking cores, Saudi rice diversity, Indian minor millets, Species distribution modelling, Pollinator diversity
- Chloroplast heterogeneity and historical admixture within the genus Malus. Three genetic networks within the genus, with the cultivated species in one of them.
- Subgenomic Diversity Patterns Caused by Directional Selection in Bread Wheat Gene Pools. Five subpopulations, dividing the European from the Chinese material. Some parts of the genome more in need of diversity than others.
- Biodiversity of Lactuca aculeata germplasm assessed by SSR and AFLP markers, and resistance variation to Bremia lactucae. Some race-specific resistance in the wild relative in Israel-Jordan, but nothing extraordinarily efficient.
- Using Multi-Objective Artificial Immune Systems to Find Core Collections Based on Molecular Markers. Very fancy math not only picks populations to maximise diversity, but also potentially at the same time minimises distance from the office.
- Assessment of ISSR based molecular genetic diversity of Hassawi rice in Saudi Arabia. It’s not just one thing.
- Minor Millets as a Central Element for Sustainably Enhanced Incomes, Empowerment, and Nutrition in Rural India. Holistic mainstreaming pays dividends.
- Minimum required number of specimen records to develop accurate species distribution models. Depends on prevalance, but 15 is a good rule of thumb.
- Microsatellite Analysis of Museum Specimens Reveals Historical Differences in Genetic Diversity between Declining and More Stable Bombus Species. Species which declined less diverse than species which did not.

Phenological diversity for nutrition
A recent blog post by the World Agroforestry Centre described their idea of a phenologically varied “fruit tree portfolio” to provide nutrition throughout the year. In Machakos, Kenya, where the portfolio is being tested out, these would be the species involved, a mixture of the local and the exotic:
A nice idea, and it reminded me that you can also do something similar by exploiting within-species diversity in seasonality. The example I know best comes from Diane Ragone’s work on breadfruit. This is from a presentation she gave recently at USAID.
Planting multiple varieties carefully chosen from each of these different groups means you can count on having some fruit throughout the year, most years. Great to have diversity at multiple levels to play around with.
