Abstract
This investigation was conducted for confirming the superiority of hegari group and/ or sudangrass group as pollen parents and clarifying the effects of forage characteristics of male-sterile line on forage yield in hybrid forage sorghum. Hegari group and sudangrass group were proved to be the excellent pollen parents by means of their greater heterosis and general combining ability in F1's. It was also suggested that forage characteristics, especially stem length, of male-sterile line did not affect on yield and its components in hybrid forage sorghum.
