Chasing melons in Central Asia
I’ve been meaning to post a link to Eric Hansen’s entertaining “In Search of Ibn Battuta’s Melon” for ages. Published in 2015 in AramcoWorld, its title says it all. Intrigued by a wonderful, and wonderfully expensive, Mirza melon from California, Hansen recalls the following passage from the celebrated Moroccan traveller, and resolves to find the melons in question — “the best of all dried fruit” no less — in their native Uzbekistan.
There are no melons like Khorezmian melons maybe with the exception of Bukharian ones, and the third best are Isfahan melons. Their peels are green, and the flesh is red, of extreme sweetness and firm texture. Surprisingly, they cut melons into slices, dry them in the sun, put them into reed baskets as it is done with Malaga figs, and take them from Khorezm to the remote cities in India and China to sell. They are the best of all dried fruit.
Needless to say, he finds them, or something that he decides is much like them, though he also comes to see the pointlessness of the quest.
In the closing hours of my quest, I realized that over the 681 years since Ibn Battuta’s visit to Khorezm, Uzbek farmers had been hard at work perfecting the art of melon breeding and growing. By saving old local melon seeds, creating and improving new varieties and passing down specialized horticultural practices according to regional water quality, soil types and climatic conditions, they had no doubt improved the disease resistance, shelf life, yield, texture, degree of sweetness and complexity of flavors of melons throughout the different growing areas. And then there was the issue of random variations due to natural hybridization in the melon fields to consider. With all of these factors in mind, it would not be surprising—even likely—that Ibn Battuta’s melon had evolved into something quite different, disappeared entirely, or simply fallen out of favor because other, more recent varieties were better.
Hansen has helpful guides in Uzbekistan, not least the authors of the book Melons of Uzbekistan. He doesn’t however, link to the book, which is available online. I’m happy to rectify that oversight here.
Nibbles: Apple edition
- A new, better apple genome. I thought once it was done, it was done. Clearly not.
- An FBI agent on the tracks of old apples. No need for high quality genomes.
- Getting to the bottom of the Honeycrisp.
- It’s the rootstocks, stupid.
- What made Milwaukee famous is not heirloom apples, but still.
- Let’s not forget the crab apple, shall we?
Good question?

Brainfood: Iron beans, Citrus evolution, Ethiopian co-ops, Farmer evaluation app, Exotic breeding, Cost of doing business, Plummy, Italian pears, Chinese cowpea, Breadfruit phylogeny, Seed collecting
- Iron beans in Rwanda: crop development and delivery experience. 800,000 households, discontinuation rate 11%. But the health outcomes? Too early, I guess.
- Phylogenetic origin of limes and lemons revealed by cytoplasmic and nuclear markers. It’s so VERY complicated.
- Seed producer cooperatives in the Ethiopian seed sector and their role in seed supply improvement: A review. Sitting between the formal and informal seed systems, they “play a key role in meeting seed demand and contribute greatly to seed supply improvement through high-volume production of seed, crop, and variety diversification, and seed delivery to farmers.”
- Gamification of farmer-participatory priority setting in plant breeding: Design and validation of “AgroDuos”. Based on pairwise ranking. I remember doing it by hand, but it’s nice to have the app. And there’s more.
- Emerging Avenues for Utilization of Exotic Germplasm. It comes down to the collections being better characterized and understood.
- Genetic resource policies in international collaborative research for food and agriculture: A study of USAID-funded innovation labs. Transaction costs are rising. Well, yeah.
- Plums: A Brief Introduction. Will keep you regular.
- Characterization and phylogenetic analysis of ancient Italian landraces of pear. Some synonyms found, some unknown things identified. All very worthy.
- Genetic diversity and a population structure analysis of accessions in the Chinese cowpea [Vigna unguiculata (L.) Walp.] germplasm collection. The Chinese stuff is different to the African stuff.
- Out of Borneo: biogeography, phylogeny and divergence date estimates of Artocarpus (Moraceae). Yeah but how many can you eat?
- Effective seed harvesting strategies for the ex situ genetic diversity conservation of rare tropical tree populations. “…fewer seeds from each of a larger number of trees, … from peripheral subdivided regions of the population.”
