【 摘 要 】

Numbers of generations and ancestors in pedigree of each breeding line and cultivar of two-rowed malting barley in public and private programs in Japan were analyzed. Compared with Japanese rice pedigree, there were fewer ancestors in malting barley. The number of ancestors increased when a source of BaYMV resistance was included in the pedigree. Cluster analysis based on the coefficients of parentage could distinguish the breeding programs by old breeding lines and cultivars, but could not distinguish them by the recent materials. To develop cultivars for novel breeding objectives, it is necessary to intoduce exotic genetic resources and maintain the genetic diversity by monitoring the pedigree with the analyse of coefficients of parentage.
