We have established cross- breeding technology that is based on the genome information from gramineous crops with a highly accurate gene map, in which 3,000 barley EST markers that are highly homologous with gramineous crops (SNP) were localized on barley chromosomes 1H - 7H.
We have developed basic concepts of “chromosome-order arrays,” in which genome DNA, cDNA, and DNA markers are distributed on arrays based on the order in which they are lined up on chromosomes or with the information about their order on chromosomes.
The chromosome-order arrays make analyses of genetic information possible without bioinformatic analyses.
- In particular
- genetic type analyses of hybrids
- quantitative trait loci analyses
- genetic interaction analyses are possible without bioinformatic analyses.
- Other than the genome breeding research and development operations with the aforementioned analytical systems, we have also the following genetic markers that concern agronomic characters
- aluminum tolerant genes
- rachis-non-brittle genes
- deep-seeding tolerant related genes
- Fusarium head blight resistant genes
- skin bare genes
- culm length related genes
- spikelet-number related genes
- glume length related genes
- heading date related genes
- ear length related genes
- rachis-internode length related genes
- dormancy related genes
- thousand-kernel-weight related genes
- spike-glossy ear controlling genes
- lemma color controlling genes
- aleuron-layer color controlling genes
- rachis brittleness controlling genes
- flowering type controlling genes
- barley yellow mosaic virus(BaYMV) resistance genes
