| Abstract | Two-line hybrid rice can be produced using male sterile line in which male sterility is controlled by nuclear gene expression, influenced by environmental factors such as photoperiod (photoperiod sensitive genic male sterility, PGMS) or temperature (thermo-sensitive genic male sterility, TGMS). At present, the function of male sterility gene is still unclear. To locate the position of male sterility gene, Indel markers were generated from 121 male sterile individuals out of 527 total F2 population obtained from a cross between TGMS B8 (IR75589) and the wild-type Azucena. The gene tgms was mapped to the interval between 2gAP003974 (0.4 cM) and 2gAP005756 (2.4 cM) markers. Information obtained from Gramene rice database indicated that these two markers are on chromosome 2 at 5.9 and 7.26 Mb, respectively. Development of these DNA markers will be beneficial for rice genetic improvement. |
