Variation in growth and nodulation of Glycine wightii under controlled environment

Abstract

The growth and nodulation of Glycine wightii (formerly G. javanica L.) were studied in two experiments with several effective strains of Rhizobim under controlled environment, with the aim of producing lines with improved nodulation and nitrogenfixing ability. Significant differences were found between the accessions in their ability to nodulate and also between the strains in their symbiotic effectiveness. Variation within lines for dry weight per nodule and time to nodule appearance was large. The results indicated that total nodule weight per plant is a suitable character for selection in a breeding programme to improve noddation in G. wightii.
