Variation of stalk mechanical strength in sugarcane population. A Venn diagram representing the number of sugarcane genotypes used for mechanical strength measurement. B, C Variated distribution of RPR (B) and breaking force (C) in sugarcane stalks. D Correlation analysis of sugarcane stalk RPR in 2019 and 2020. E Correlation analysis between RPR and breaking force in sugarcane genotypes. RPR rind penetrometer resistance. ** indicated statistically significant correlation at p < 0.01 level
