Abstract:

Eight maize inbred lines were used as tested materials, with shading treatment (90% shading control) from seeding stage to maturity stage. The experiment of two factors split-plot design was carried out to study the shade-tolerance and plant traits’ changes of the maize inbred lines. The order of the shade-tolerance level of the materials was: 06CIn967-11>06CIn892-2>06CIn967-4>06CIn892-11>06CIn891-4>06CIn891-15>06C984-2>06 C984-8, the difference of the inbred lines of same source wasn’t significant; there was certain difference among inbred lines of different source. The plant and leaf growth, tassel differentiation was restrained significantly; the shading reaction between different genotype lines was different. The shading reaction of different character was also different. The reaction of the tassel differentiation was the strongest of all. The shade-tolerance type inbred lines should be selected based on the traits changes of different maize inbred lines.
