Having measured the effectiveness of atmospheric N. fixation the macro- or micro-symbionts as well as agronomic factors can be manipulated with the objective to maximize biological nitrogen fixation. A suitable method to quantify nitrogen fixation is therefore necessary in any programme aiming a

Studies have shown that selection to increase N. fixation will be successful if: (.) discriminating traits (selection criteria) are measured precisely, (.) variability in ge

Effective mutagens are available, but the bottleneck is the effective selection of rare desired variants from large mutagenized populations. Selection methods m
