abstract: A range of groundnut (Arachis hypogaea L.) genotypes, representing the cultivated botanical groups, were grown at ICRISAT Center, India. In 3 experiments, 3–8 genotypes were grown at various plant-population densities. In a fourth experiment, 27 genotypes were grown at a constant spacing. Acetylene reduction (AR) and fractional light interception (f) by these cultivars were measured at several stages of crop growth. Plant population (density), sample date and genotype influenced both the AR rate m-2 and the fraction of light intercepted; variables that were well correlated. In 3 experiments, ca. 90% of the statistical variation in AR rate m-2 was attributed to variations in f. In the remaining experiment, genotypic variance was 46% of the explained variance; one genotype (Gangapuri) had consistently low AR across the range of populations, however in the other experiments Gangapuri did not differ from other cultivars in AR/f, when sampled at earlier stages of development
