Abstract
Red clover is an important forage legume widely cultivated in most temperate regions. However, its usefulness is limited due to its short perenniality. Perenniality is determined by interactions among various factors, such as biotic abiotic stress and flowering characteristics, which are controlled by QTLs. Growth monitoring of red clover individuals during plant growth period should be efficient for revealing and splitting up the factors those contribute to perenniality. However, traditional growth analysis required sampling of plants, and it was impossible to chase individual growth habit of the field plants by nondestructive inspection. In this presentation, we reported the result of growth monitoring of red clover individuals on the field level using Field Imaging System and QTL detection with the obtained data. Field Imaging System was a measuring device of field plants, composed with personal computer, digital camera and software for picture filming and instrumentation.
