| Outline of Final Research Achievements |
The use of heterosis is effective in improving grain yield in sorghum, as in other cereals. The identification of the genome-wide gene regulatory networks underlying the spikelet- and grain-related traits is very important for the rapid and efficient development of high yielding grain sorghum varieties via the use of heterosis. However, in sorghum, which has a short history of modern breeding, these networks have remained largely unknown. In this study, we have developed the cross populations and the genome data for accurate genetic analysis of spikelet- and grain-related traits in sorghum, and succeeded in comprehensively identifying the genetic loci that regulate these traits.
