Progress in selection of Bradyrhizobium strains At IITA-Ibadan, four soybean genotypes (TGx 1448-2E, TGx 1485-1D, TGx 1838-5E, and TGx 1906- 3F) were inoculated with 20 Bradyrhizobium strains in 2008. One milliliter portions of broth cultures were used to inoculate each of six seedlings of the four genotypes grown in beach sand with regular supply of plant nutrient solution. The controls were plus N (70 ppm) and non-inoculated control (minus Rhizobium and minus N). Plant cultures were maintained in the greenhouse for 10 weeks (10 June to 19 August 2008). Soybean genotypes inoculated with Bradyrhizobium strain RAUG1 and RAUG2 had the highest shoot nitrogen concentration and these figures were significantly higher than that of soybean genotypes inoculated with the other strains (Table 11-25). It is important to state that the lower shoot nitrogen concentration reported for some of the genotypes might have been due to dilution effect associated with larger shoot biomass compared to that of soybean genotypes inoculated with RAUG1 and RAUG2. The high performing Bradyrhizobium strains have been multiplied and the inocula tested on many more soybean genotypes under field conditions.
