Association analysis revealed loci linked to post-drought recovery and traits related to persistence of smooth bromegrass (Bromus inermis)

Association analysis has been proven as a powerful tool for the genetic dissection of complex traits.This study was conducted to identify association of recovery, persistence, and summer dormancy fortiflex stable super fork - head only blue with sequence related amplified polymorphism (SRAP) markers in 36 smooth bromegrass genotypes under two moist
