Abstract
The occurrence of nodulation, and whether it is effective or ineffective, depends on the genetic compatibility between the rhizobia and the legume. In this chapter, symbiotic promiscuity and specificity for nodulation are demonstrated using inoculated legumes grown in Leonard jars and seedling-agar tubes. The disadvantages of the cross-inoculation concept in classifying rhizobia are demonstrated. However, the practical significance of the cross-inoculation concept in the correct practice of seed inoculation is highlighted.
