Abstract

 Quantitative traits, including juvenile growth, flower bearing and rooting ability, of a woody plant species, Cryptomeria japonica D. Don, were analyzed in a three-generation pedigree with 73 F2 progenies using a linkage map with 85 genetic markers (72 RFLP, 11 RAPD, one isozyme and one morphological loci). A cluster of quantitative trait loci (QTLs) related to juvenile growth and female flower bearing was detected on linkage group 2. Some of the influence of this cluster could be attributed to pleiotropic effects of a dwarf locus located in its vicinity. QTLs related to male and female flower bearing were detected at different locations and showed different effects from each other, suggesting that the genetic systems controlling male and female flowering are different. No large QTL affecting rooting ability was detected in the material analyzed in this study.
