Genetic Mapping of <i>ms1s</i>, a Recessive Gene for Male Sterility in Common Wheat
The utilization of heterosis is an important way to improve wheat yield, and the production of wheat hybrid seeds mainly relies on male-sterile lines. Male sterility in line 15 Fan 03 derived from a cross of 72,180 and Xiaoyan 6 is controlled by a single recessive gene. The gene was mapped to the di...

| Summary: | The utilization of heterosis is an important way to improve wheat yield, and the production of wheat hybrid seeds mainly relies on male-sterile lines. Male sterility in line 15 Fan 03 derived from a cross of 72,180 and Xiaoyan 6 is controlled by a single recessive gene. The gene was mapped to the distal region of chromosome 4BS in a genetic interval of 1.4 cM and physical distance of 6.57 Mb between SSR markers Ms4BS42 and Ms4BS199 using an F<sub>2</sub> population with 1205 individuals. Sterile individuals had a deletion of 4.57 Mb in the region presumed to carry the <i>Ms1</i> locus. The allele for sterility was therefore named <i>ms1s.</i> Three CAPS markers were developed and verified from the region upstream of the deleted fragment and can be used for <i>ms1s</i> marker-assisted selection in wheat hybrid breeding. This work will enrich the utilization of male sterility genetic resources. |
