| Abstract | Strains in Bradyrhizobium japonicum serocluster 123 are the major indigenous competitors for nodulation in a large portion of the soybean production area of the United States. Serocluster 123 is defined by the serotype strains USDA 123, USDA 127, and USDA 129. The objective of the work reported here was to evaluate the ability of two soybean genotypes, PI 377578 and PI 417566, to restrict the nodulation and reduce the competitiveness of serotype strains USDA 123, USDA 127, and USDA 129 in favor of the highly effective strain CB1809 and to determine how these soybean genotypes alter the competitive relationships among the three serotype strains in the serocluster. The soybean genotypes PI 377578 and PI 417566 along with the commonly grown cultivar Williams were planted in soil essentially free of soybean rhizobia and inoculated with single-strain treatments of USDA 123, USDA 127, USDA 129, or CB1809 and six dual-strain competition treatments of USDA 123, USDA 127, or USDA 129 versus CB1809, USDA 123 versus USDA 127, USDA 123 versus USDA 129, and USDA 127 versus USDA 129. PI 377578 severely reduced the nodulation and competitiveness of USDA 123 and USDA 127, while PI 417566 similarly affected the nodulation and competitiveness of USDA 129. Thus, the two soybean genotypes can reduce the nodulation and competitiveness of each of the three serocluster 123 serotype strains. Our results indicate that host control of restricted nodulation and reduced competitiveness is quite specific and effectively discriminates between B. japonicum strains which are serologically related. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
