The recombinant inbred lines( RILs) were formed by crossing an individual Zheng 58 plant( female)with an individual HD568 plant. Rind penetrometer resistance( RPR) was investigated with an electronic rind penetrometer in seven stages at independent environment. The inheritance of maize RPR was captured with the methods of phenotypic analysis,complex variance analysis,and joint analysis of multiple generations. The result indicated that the narrow-sense heritability estimates of RPR was 75. 58%. The inherita...
