Project Type: Nonfunded Cooperative Agreement

Start Date: Sep 01, 2007
End Date: Jul 31, 2012

Objective:
Identify the genetic map location of genes controlling pollen fertility restorer in sorghum. Identify potential candidate genes controlling pollen fertility in sorghum. Elucidate the mode of action of fertility restorer genes in controlling pollen viability in sorghum hybrids.

Approach:
Utilize existing molecular marker technology to locate the genetic map position of fertility restorer genes. Utilize the physical map of sorghum and the emerging sequence of the sorghum genome to identify potential candidate genes. Compare sequence of candidate fertility restorer genes to known fertility restorer genes to understand the mode of action of these genes in crops.
