The color of male strobili of individual sugl trees (Cryptomeria japonica D. DON) has tree to tree variation from yellow to black and does not vary appreciably within a tree or from year to year in the same trees. Crosses between parents with yellow strobili produced only yellow strobilar progeny. Crosses between parents with black and yellow strobili produced black and yellow strobilar progeny in 1 : 1 ratio. Then we supposed with a pair of alleles that a dominant gene, B, colored male strobili black, a recessive gene, b colored male strobili yellow, and a heterozygous pairing colored them brown. As a result of a chi-square test in this postulation, there was no significant difference. Consequently, the color of male strobili of sugi is conclude to be controlled by incomplete dominant inheritance.
