摘 要 ：矮败小麦是具有矮秆基因标记的显性核不育材料，显性雄性不育基因Ms2与显性矮秆基因Rht10连锁十分紧密，其连锁交换值仅为0.18，而紧密连锁基因Ms2和Rht10与着丝点间的遗传距离为31.17个交换单位。

Abstract:“Dwarf Male-sterile Wheat” is a dominant genic male sterile material bearing a dwarf marker. The genes Ms2 for male sterility and Rht10 for dominant dwarfness located on the short arm of chromosome 4D are closely kinked with a crossing-over value as small as 0.18. The present paper further reveals
