Présentation
Systematic genomic analysis of sorghum panicle traits can lead to accelerate genetic improvement for the increment in yield capacity. Therefore this study is aimed to exploit the intraspecific variation of panicle traits across the sorghum core collection from around the world to evaluate not only a wide range of the phenotypic diversity but also its suitability for association analysis. The value of these traits, the relationship to the yield components and the preliminary effort for the association mapping may provide useful information for sorghum breeding.
Therefore the main objectives of this study are : (1) to evaluate the variation of panicle patterns across a world-wide collection of sorghum germplasm, (2) to identify the main components related to sorghum inflorescence architecture, (3) to clarify the relation between panicle component traits and yield related traits, and (4) to identify QTL underlying inflorescence architecture by genome wide association analysis.
