The genomes of the wheat are directly manipulated and engineered which would then resist droughts, be more healthy, and thrive and grow in harsh conditions.
Wheat is one for the three most important crops in the world. Since the start of the agricultural age, humans have been feeding and farming wheat.
The genetically modified wheat can resist insects, herbicides, fungus, and viruses. It also has improved nutrition and increased yield.
Genetically modifies wheat has not been commercially available as of yet.
Floods! Floods don't really happen to much, but there was a big one which caused the land to become super moist. Which made it difficult to do Dry Farming. I hope this helped! :)
