There’s a nice article in Rising Kashmir highlighting that region’s cold-tolerant maize landraces as a unique source of genetic diversity. What I liked about it is that it doesn’t condescend to its audience. It’s unapologetically technical and niche, while successfully (I think) striving to be understood by all. That’s rare. The author, Dr Salika Ramazan, argues that long adaptation to Himalayan environments has produced valuable traits for climate resilience and future maize breeding, and advocates for urgent conservation before this irreplaceable diversity is lost.
A quick search on Genesys revealed 302 maize accessions from above 1500 masl in the Himalayas (yellow on the map below), and 62 above 2500 masl (red). Of course, there are many more maize accessions from high altitudes in Central and South America, but their photoperiod adaptation (among other things) is likely to be quite different.
