Genome-wide association analysis uncovers the genetic architecture of tradeoff between flowering date and yield components in sesame

Abstract Background Unrevealing the genetic makeup of crop morpho-agronomic traits is essential for improving yield quality and sustainability. Sesame (Sesamum indicum L.) is one of the oldest oil-crops in the world. Despite its economic and agricultural importance, it is an ‘orphan crop-plant’ that...
