Extensive phenotypic variation of rind penetrometer resistance in each RIL population. a Diagram of the RPR measurement. The cross-sectional area of the probe is 1 mm2. b Hierarchical clustering of RPR evaluated in seven stages in each RIL population. Height is defined as the Euclidean distance between clusters. c Phenotypic variation of RPR measured in seven stages across multiple environments. HO: the high-oil population (B73 × BY804); LR: the lodging-resistance population (Zheng58 × HD568); RPR: rind penetrometer resistance; V10: the tenth-leaf stage; DTS: days to silking; AS10: 10 days after silking; AS20: 20 days after silking; AF30: 30 days after silking; AS40: 40 days after silking; AS50: 50 days after silking; 2012B: Beijing in 2012; 2012H: Hainan in 2012; 2013B: Beijing in 2013
