Summary
Rhizosphere population characteristics of two cultivars of spring wheat (Triticum aestivum L. emend Thell.), Rescue (R) and Cadet (C), and the related chromosome substitution lines, C-R5 B and C-R5 D, were investigated. Replacement of the chromosome pair, 5 B, in Cadet with 5 B from Rescue made many of the rhizosphere microbial characteristics of C-R5 B similar to or the same as those in the rhizosphere of the donor parent, Rescue. In contrast, substitution of the functionally related chromosome pair, 5 D, did not cause marked changes in the rhizosphere microbial population, demonstrating the specificity of the plant's control over factors governing the rhizosphere microbial environment.
