主　　题：foxtail millet(Setaria italic L.Beauv.) highly male-sterility gene mapping SSR marker 

摘      要：Breeding of male-sterile lines has become the mainstream for the heterosis utilization in foxtail millet,but the genetic basis of most male-sterile lines used for the hybrid is still an area to be *** this study,a highly male-sterile line Gao146A was *** analysis indicated that the highly male-sterile phenotype was controlled by a single recessive gene a single recessive *** F 2 population derived from cross Gao146A/K103,one gene controlling the highly male- sterility,tentatively named as ms1,which linked to SSR marker b234 with genetic distance of 16.7 cM,was mapped on the chromosome *** results not only laid the foundation for fine mapping of this highly male-sterile gene,but also helped to accelerate the improvement of highly male-sterile lines by using molecular marker assisted breeding method.
