Potential of rice landraces with strong culms as genetic resources for improving lodging resistance against super typhoons

Abstract It is generally believed that rice landraces with long culms are susceptible to lodging, and have not been utilized for breeding to improve lodging resistance. However, little is known about the structural culm strength of landraces and their beneficial genetic loci. Therefore, in this stud...
