- Abstract:
- Soybean [Glycine max (L.) Merrill] has the ability to form root nodules in a symbiosis with bacteria from which it can gain a better nitrogen supply. The aim of this study was to phenotype nodulating and non-nodulating, near isogenic soybean lines with regard to leaf chlorophyll content, time to maturity, pod number, 1000 seed weight, seed protein and oil content. Further the suitability of image analysis for measuring chlorophyll content was tested. Nodulating lines had a significantly higher leaf chlorophyll content, higher pod number and 1000 seed weight, a lower seed oil content but a higher protein content as compared to non-nodulating lines. Time to maturity was influenced both by the genetic background and the type of nodulation. The image analysis was found to be a reliable method to measure leaf chlorophyll content. SPAD-values and seed protein content are significantly dependent on each other, so that known leaf chlorophyll content may allow an economically interesting prediction of seed protein content.
