Abstract

Thermo-sensitive genic male sterile (TGMS) lines can provide new options for hybrid seed production using "two-line" system. A set of F2 and BC1 populations derived from the cross between Qiong-6ms and Dan958 were employed to analyze the inheritance of a TGMS line Qiong-6ms and map the TGMS genes in maize. The results demonstrated that the sterility of Qiong-6ms was governed by two duplicative recessive genes, named tms1 and tms2. The gene tms1 was mapped to chromosome 5 linked with the SSR markers umc1355, umc2302 and umc1784 at a distance of 3.0 cM, 1.3 cM and 0.9 cM respectively; while tms2 was localized on chromosome 3, linked with SSR markers bnlg1605 (0.5 cM) and umc2050 (4.2 cM). These markers, which are tightly linked with the tms1 and tms2 genes, will be helpful for marker assisted selection of TGMS lines in maize.
