Selection of pea on rising of nitrogen fixation with the use of symbiotic mutants

The technology was developed for use of supernodulating mutants in pea selection for rising symbiosis efficiency. The method is based on interaction within one genotype of both recessive and dominant alleles of different sym-genes - nod4 and Nod 5, control the super- and hypernodulation. The possibility was established for simultaneous selection on rising of nitrogen fixation and productivity of macrosymbiont.
