Abstract

High nodulating mutants (two) or rhizobia associated with arid woody legume Prosopis juliflora have been isolated following ultraviolet irradiation of the parent rhizobial strain PJ -29, which is simultaneously resistant to chloramphenicol and streptomycin in addition to being nod* (nodulation positive). The isolated mutants (PJ-29a and PJ-29b) produce 16and 13 nodules/seedling as compared to only 3 produced by parent strain PJ-29 in 45 days old host seedlings. There is 33 and 37% increase in shoot length and 28 and 30% increase in plant dry weight in mutants PJ-29a and PJ-29b respectively over the wild type parent strain.
