Association mapping by aerial drone reveals 213 genetic associations for Sorghum bicolor biomass traits under drought

Sorghum bicolor is the fifth most commonly grown cereal worldwide and is remarkable for its drought and abiotic stress tolerance. For these reasons and the large size of biomass varieties, it has been proposed as a bioenergy crop. However, little is known about the genes underlying sorghum’s abiotic stress tolerance and biomass yield. To uncover the genetic basis of drought tolerance in sorghum at a genome-wide level, we undertook a high-density...
