Phorate-resistant mutant strains of chick pea (Cicer arietinum L.) Rhizobium sp. growth and their compatibility in symbiotic nitrogen fixation
Published online by Cambridge University Press: 27 March 2009
Summary
Chick pea Rhizobium strain RG3 was treated with 30 μg/ml of N-nitrosoguanidine and two mutants isolated were resistant to 2000 μg phorate/ml yet retained the capacity to form nodules. On the basis of number of nodules, their dry weight, N2ase activity, total pyridine nucleotides and active iron contents, mutant strains G11 and G26 were found to be equally effective with and without phorate and resulted in significantly greater grain yield.
