The Genomic and Phenotypic Characterization of the Introgression Line A33.18 of Pea ( L.) with the Increased Specificity of Root Nodule Symbiosis.

In pea ( L.), alleles of the gene determine the specificity of the interaction with nodule bacteria (rhizobia). The allele present in landraces from Afghanistan provides higher selectiveness toward rhizobia than the allele present in European cultivars.
