From 2003 to 2005, mineral contents in seeds of thirteen soybean (Glycine max) cultivars bred for warm region in Japan were analyzed. The potassium, phosphorus, magnesium and calcium contents (g/kg) ranged from 11.0 to 19.5, from 5.30 to 8.63, from 2.39 to 3.53, and from 1.24 to 3.25, respectively. The iron, zinc, manganese and copper contents (mg/kg) ranged from 65 to 125, from 32.3 to 56.8, from 29.0 to 42.9, and from 3.7 to 21.4, respectively. Analysis of variance for mineral contents showed that the potassium, magnesium and calcium contents were significantly influenced by the cultivars or the cultivation years at the 5 or 1% level, that the phosphorus, zinc, manganese and copper contents were significantly influenced by the cultivars at the 1% level. In the analysis of variance, total variance was divided into genotypic variance (sigmasub(v)**2), yearly variance (sigmasub(y)**2) and error variance (sigmasub(e)**2). Genotypic variance was large for magnesium content, and yearly variance was large for potassium, calcium, zinc, manganese and copper contents.
