We have preserved ca. 14,000 accessions of cultivated barley including
experimental lines and ca. 600 accessions of wild relatives. The subjects of
our research are 1) evaluation of genetic diversity and characteristics, construction
of the barley germplasm database and worldwide sample distribution, 2)
collection and preservation of barley germplasm and 3) efficient use of the
resources for genome analysis including EST, molecular markers and DNA
libraries to study the genome-based barley diversity and the genetic analysis
of important traits in barley.

| Collection and distribution of barley resources |
In addition to seed samples, cDNA and BAC clones (including
individual clones, pooled BAC DNA for screening, high-density replica membranes
and complete clone set of barley) were distributed with the support of the
National Bio-Resource Project (http://www.nbrp.jp/). |
| QTL analysis of barley seed dormancy |
A candidate of barley seed dormancy QTL on the long arm of chromosome
5H, which may be associated with pre-harvest sprouting in small grain cereals
including barley, was identified using a high density linkage map a large
segregating population from recombinant chromosome substitution lines. The
transformation and functional analysis of this candidate are underway. |

Genome analysis
|
The project ‘Identification of genes of important traits and their application
in barley breeding’ finished with support of Bio-oriented Technology Research
Advancement Institution. The project aims to sequence genes on chromosome
3H and isolate genes responsible for brewing traits and stress tolerances.
The full length cDNA projects on barley were also conducted by National
Bioresource Project and Genome diversity analysis project by MAFF.
