SRP312628 PRJNA718320 Genetic Architecture of Maize Rind Strength Revealed by the Analysis of Divergently Selected Populations The strength of the stalk rind, measured as rind penetrometer resistance (RPR), is an important contributor to stalk lodging resistance. To enhance the genetic architecture of RPR, we combined selection mapping on populations developed by 15 cycles of divergent selection for high and low RPR with time-course transcriptomic and metabolic analyses of the stalks.
