Improving N2 fixation from the plant down: Compatibility of Trifolium subterraneum L. cultivars with soil rhizobia can influence symbiotic performance

Plant genotypes of Trifolium subterraneum L. (subterranean clover) were evaluated for differences in symbiotic N2 fixation with soil rhizobia, with the long-term aim of using plant selection to overcome sub-optimal N2 fixation associated with poorly effective soil rhizobia. Symbiotic performance (SP) was assessed for 49 genotypes of subterranean clover with… (More)
