The canopy structure and leaf morphological characters of 4 sugarcane genotypes at different leaf layers on seedling were studied by using CI-100 plant canopy instrument and CI-203 area meter instrument. The results showed the leaf morphological parameters, canopy structure and radiation transmission at different leaf layers were notably different among different genotypes. The variation of Ila, Amfi, Dl at different leaf layers were mainly caused by the leaf width at relevant position. The variation of K at different leaf layers was related to Amfi and Dl. The variation of Td（transm. coef. for diffuse penetration）had significant correlations with Ila, Amfi and Dl. The variation of Tr（transm. coef. for radiation penetration）had significant correlations with Dl, leaf width and the ratio of leaf length to width. The variation of Par had significant correlations with Ila, leaf area, leaf width and the ratio of leaf length to width.
