Four Rhizobium strains known to produce differences of up to 100 per cent in the vegetative dry weight of a test cowpea cultivar were used as separate micro-symbionts in combination with four semi-erect cowpea cultivar with contrasting grownh habits. The nodulated plants ere grown in pots under controlled temperature conditions in a plastic house during U.K. summer months and cultivar-strain interactions with respect to vegetative and reproductive performance were recorded. Significant differences between and within cultivars were recorded for almost all components of vegetative growt and seed yield. Although a single Rhizobium strain was not clearly superior fol all cultivars tested, those isolated from tropical soils grave generally greater seed yields than the exotic strains tested. The significance of cultivar-strain selection in cowpea breeding strategies is discussed. |
