ABSTRACT The objective of this study was to investigate the effects maturity, genotypic background, and maximum temperature 20 d before maturity on soybean [ Glycine max (L.) Merr.] seed mineral concentrations. A field experiment conducted in Stoneville, MS, 2004 2005, using two sets near‐isogenic lines that differed genes. One set isolines derived from cultivar Clark other Harosoy. each line within a varied, but all had common background. For isolines, there were positive correlations ( P < 0.05) between N with r = 0.83 0. 62 Ca 0.59 0.89 2005).

Generally contribution or total variation nutrient concentrations greater than temperature. This information may be useful when developing germplasm higher content by genotypes uptake efficiency trait as either parental source material improve existing varieties for nutrition trait.
