Question: So when you understand which genes make the plant look that way, what will you do then?

Imagine genes to be Lego building blocks. Once we understand what they do and how they work together, you can very specifically adapt a plant made from these blocks to look and respond (to the environment) in a particular way.
Wheat originally comes from the Middle East (The Fertile Crecent), but is grown worldwide in very different environmental conditions. Farmers plant it from Norway and Russia at 65° northern latitude to Argentina at 45° southern latitude. It’s safe to say that the climate in Norway is very different from Argentina, yet the varieties of wheat grown there are not well adapted to the particular environemntal conditions. So by understanding all the Lego building blocks, you can “build” a plant for any particular environment.
In addition, our climate is changing, so we need to be able adapt our crops (not just wheat) to these changing conditions. So there is a lot of work to be done 🙂
