| Abstract: | A new wheat line,YW243,was studied on BYDV resistance test in the field,cytological analysis and genomic in witu hybridization(GISH).the results are as follows:YW243 was with the somatic chromosome number of 42 and twenty one bivalents at MⅠPMCs.YW243 which highly resistant to GPV and GAV strains of BYDV was homozygous translocation line (T7DS·7DL-7XL) with a pair of BYDV resistance gene.YW243 with stable resistance and good agronomic character can be directly used as parent for BYDV resistance breeding programs. |
