“…Legend: See Figure 1, Therefore, we have demonstrated that the efficiency of the "alfalfa-R. meliloti" symbiosis depends significantly on the genotypes of both partners. Previously a number of authors (Burton and Wilson, 1939;Erdman and Means, 1953;Gibson, 1962;Mytton et , 1984;Provorov and Simarov, 1990;Tan and Tan, 1986) have published variable values for the inputs of partners' genotypes into determination of efficiency for this symbiosis (4,8-39,8%, 7,2-32,4% and 6,0-47,0% for plant genotypes, bacterial genotypes and genotype interaction, respectively). We suggest that this inconsistency is partially due to measurements of symbiotic efficiency using plants of different ages.…”

“…This has been shown to lead to the accumulation of up to 200-400 kg N ha-i from the atmospheric N2 fixation (Berestetsky et al, 1987;LaRue and Patterson, 1981). Analysis of variance on data of alfalfa -R. meliloti interaction has revealed that symbiotic efficiency is controlled by both partners through additive and non-additive interaction of their genotypes (Burton and Wilson, 1939;Erdman and Means, 1953;Gibson, 1962;Mytton et al, 1984;Provorov and Simarov, 1990;Tan and Tan, 1986). At the same time the contributions of partners' genotypes to the observed variation of symbiotic efficiency differed greatly from one experiment to another and ranged from 4,8 to 39,8% for additive effects of cultivars, 7,2 to 32,4% for additive effects of strains and 6,0 to 47,0% for the non-additive interaction of partners.…”

“…They found, though, that the relatiQnship was affected by environmental conditions that tended to mask the influence of the host plant. In a more recent study Erdman and -Means (1953) studied the development of 21 strains of R. meliloti on three lucernes. The variety Du Puits showed good acceptance of most strains, and they suggested that this type of varietal compatability with a wide range of rhizobia could account for the agronomic adaptability of such a variety of lucerne to a diversity of soil conditions.…”

“…Many authors have investigated, in the greenhouse, the influence of various Rhizobium meliloti strains on fuIedicago sativa and other species (Burton and Wilson 1948;Gibson 1962;Leach 1968;Erdman and Means 1953;Melkumova 1957;Hamatova1965;Brockwell and Hely 1966 The strain effects were highly significant in the second cut of the second experiment only, whereas the strain X cultivar interaction was considerably attenuated here (Table 1).…”
