Abstract

In 1963, Tang and Li reported on a study of a cross, Glycine max x G. formosana (G. formosana = G. soja), in which the inheritance of a number of qualitative traits was determined. This paper is a reinterpretation of a portion of their data. Among the genes segregating in the cross were the following: i^i/i: restriction of dark seedcoat pigments to hilum/self-dark seed G/g: green seedcoat/yellow seedcoat (obscured in ii genotypes) B2,B3/b2, b3 : two of the three complementary factors for bloom on seedcoat; in the cross studied, both parents were B1B1, so that segregation at the other two loci produced F2 ratios of 9 bloom : 7 smooth.
