Rind penetrometer resistance is one of the main factors affecting maize lodging resistance.A total of 113 maize inbred lines were used to evaluate rind penetrometer resistance in two environments.All the tested inbred lines were divided into four groups via cluster analysis based on the level of rind penetrometer resistance.Nine inbred lines with high rind penetrometer resistance values were selected.These nine in-bred lines were divided into five heterotic populations using 32 853 SNP markers.The results provided important references for genetic improve-ment of maize lodging resistance and breeding novel maize varieties with lodging resistance.
