    It was rather neat to read through the article (esp. nice little infographic about pistachio development in the latter half), but dunno if this better, more detailed sequencing of the most common pistachio cultivar is going to be very helpful to current growers of 'stachios.
    Like, it takes 7-10 years for a tree to reach maturity & start producing nuts. If you need trees that are better adapted to warmer winters, the time to be working on that was several years ago.
    But hey, maybe this group has other publications detailing other cultivars that are less stressed by heat? That, I think, would be more valuable to growers.

      UC Davis and UC Berkeley has been working on producing heat, drought, and disease tolerant pistachios varieties for years. This is a part of continued ongoing research. Additonally, UC Davis usually offer classes every few years on pistachio tree farming fyi.

      This research will help to develop more robust plant varieties by identifying specific genes for certain favorable charactetistics or to grow at certain climate. More varieties will help growers to choose trees more favorable to both their environment and financial means. (Paper on pistachio varieties: https://ucanr.edu/sites/default/files/2011-02/73687.pdf)

      I'm not an agronomist or plant biologist. My background is more on broader environmental land management. I have delve into this topic since my FIL is starting his own pistachio farm and worked on USDA grants (until DOGE took away funding). Establishing pistachio trees for cultivation is a long process, and it is fairly expensive. More information like this helps growers to protect their investments. The pros to pistachio is that it requires less water than other nut trees like almond, and it is already hardy against drought. Which is why my FIL is investing in them over olives or grapes.

      Right now in his particular region (not the US), they spliced two varieties from UC Berkeley together. One for robust root system and other for larger nut production. When I toured the pistachio farm down in south america, the growers have about 20 years of experience to figure to see what varieties and methodology worked so far. It would be good to have more varieties available to have more resilent crop for any future production. In general, you don't want to invest on one specific varieties just in case something happens (like a specific disease). So understanding their genome will help to create new varieties that can grow in wider condition. The region my FIL is in only recently started pistachio production and so more experimentation is needed to establish better management practices and more robust production for both climate change and regional knowledge.

      Also with silvopasture (I know this from working with apple orchards). You want to offset the ages of your trees. So you have fields of different ages. One field at a certain age, and another different few years apart. You don't want trees of same age all at once.
      This way you can properly prepare to retire mature unproductive trees and plant new ones or different crops. So current growers may want different varieties since they might have mature trees they want to retire.
