The effect of selection for high seed protein content on plant development in soybeans (Glycine max (L.) Merr.) was investigated by comparing the lengths of growth stages of four selected populations with those of a nonselected control. Each population, grown at two locations in one season, was a composite of four crosses between G. max and its putative wild ancestor, Glycine soja Sieb. and Zucc. The growth stages were planting to emergence, emergence to flowering and flowering to maturity. The length of each growth stage was measured in soybean development units (SDU) and in days. On average, populations selected for protein alone required more SDUs from planting to emergence and from emergence to flowering and fewer SDUs from flowering to maturity than did the control. The mean temperature in the stage from flowering to maturity was negatively correlated with protein content in all populations. The correlations ranged from −0.22* to −0.34**.

Selection For

Early generation selection for high seed-protein content would be desirable in breeding programs attempting to combine high yield and high protein content in soybeans (Gycine max (L.) Merr.). The heritability of seed-protein content in the F2 and F3 was measured in four crosses and mass and family selection for protein were compared in the F3 of these crosses. Glycine soja Sieb. and Zucc., a putative wild ancestor of the soybean, was the male parent in all crosses and selection intensity was at 10%. The heritability of protein in the F2, calculated by parent-offspring regression, was 27%. The broad-sense heritability of protein in F3 families grown over two locations in one season was 78%. Mean protein content for every selected population was greater (P ≤ 0.01) than the mean for the non-selected control population (45.3%). Mean protein contents of the F4 populations resulting from these selection methods were: mass selection in the F2 and F3, 48.0%; mass selection in the F3 following one generation of single seed descent, 48.8%; selection among F3 families, 47.6%; selection among and within F3 families, 47.5%. Either method of mass selection was superior to either method of family selection at the 0.01 level. Although early selection (mass or family) raised the mean protein content of a population, segregation continued to give rise to low-protein genotypes thereby requiring further selection.

Percentage Protein

Six cultivars and five plant introductions of Glycine max L. Merr. varied in picograms of DNA per cell from 1.84 to 2.61, and in number of ribosomal-RNA genes per 2 C nucleus from 960 to 2431 (Laboratory 1, Ames) and from 768 to 2095 (Laboratory 2, Rhinelander). The parameters did not correlate with seed protein content, which varied from 32.8% to 52.6%. With these materials, use of the rRNA locus size as a breeding tool for increasing percentage protein content by use of cytogenetic and genetic manipulations is not warranted.
