| Research Abstract |
Using cross-family derived from CR46, which bears abundant male strobili every year, association between DNA polymorphism and male strobili abundance was investigated. Stable and strong quantitative trait loci (QTLs) were detected. Association between genotype of markers in the detected QTL region and male flower abundance were further investigated using 150 plus-trees selected from Kanto region. Significant association was detected for one locus, and genomic clone including this locus has been isolated.
