The inheritance of main diterpene components, (-)-kaurene, (+)-phyllocladene and (-)-sclarene, in the leaves of Sugi (Cryptomeria japonica) was investigated. Sugi seedings of fifty-eight combinations obtained from crossing among twenty clones were analyzed by gasliquid chromatography for diterpene hydrocarbons. Experimental results indicate that the biosynthesis of the diterpenes in the leaves of Sugi is genetically controlled with P and K genes. The dominant gene P controls formation of (+)- phyllocladene through (+)-copalylpyrophosphate, and the recessive gene p controls the cyclization to an intermediate (-)-copalylpyrophosphate that can be converted to either (-)-kaurene or (-)-sclarene. A genotype having recessive pp and dominant K genes produces (-)-kaurene, on the other hand, a genotype having both recessive genes ppkk produces (-)-sclarene.
