| Abstract: | Dwarf Male-sterile Wheat" is a dominant genie male sterile material hearing a dwarf marker. The genes Ms2 for male sterility and Rht10 for dominant dwarfness located on the short arm of chromo-some 4D are closely linked with a crossing-over value as small as 0. 18. The present paper further re-veals that a recombination percentage of Ms2 and Rht10 with the centromere is 31.17. |

| Keywords: | Dwarf Male-sterile Wheat Crossing-over value Gene-centromere distance |
