Two gene analyses were made using the selfed families from a twisted-leaf sugi (Cryptomeria japonica D. DON). For the testing of linkage, two procedures, namely the conventional Chi-square test and the AKAIKE's Information Criterion (AIC) were applied. The first analysis dealt with a dominant gene for leaf-twisting (T), a recessive dwarf gene (dw), and an embryonic lethal gene (l_1.). In the second analysis, peroxidase isoenzyme genes of E and F (the symbols of E and F are conveniently named for band presence) were studied. It was found that T links with l_1 in the coupling phase and that the recombination value is 27.4±3.06%. No linkage was found between T and dw. In the second analysis, with ordinary computation of the linkage, a recombination value of 13.1±5.29% was estimated. Meanwhile, if AIC had been applied, another recombination value of 39.3±8.44% was possible when the viability of the genotype of eeff might have been lower than that of the other possible genotypes in the progenies. It is considered that AIC is more useful and to provide broader information in comparison with the single use of the conventional Chi-square computation.
