Genotypic variation of N2-fixing common bean (Phaseolus vulgaris L.) in response to iron deficiency.

Abstract excerpt

In calcareous soils, the yield of grain legumes is often limited by the lower availability of iron (Fe), especially when they depend upon symbiosis with root nodule bacteria for their N nutrition. In order to explore the variability of responses of N(2)-fixing common bean to Fe deficiency the common bean white-seeded lines Striker and Coco blanc, and coloured-seeded lines SVM-29-21 and ARA14 were inoculated with...
