Soybean seed composition is the major determinant of soybean price. The value of all other factors that affect crop yield and quality, such as genetics, environment, and management, will be based on the value of the soybean seed produced by that technology.
Who determines Soybean seed composition
Soybean seed composition is determined by the genotype of the plant (i.e., the genetic code) and the environment in which it was grown (i.e., nitrogen fertility, water availability, etc.). There are two major types of soybean seed composition differences: quantitative trait loci (QTLs), which are regions of DNA that are inherited in a predictable fashion and that typically have small effects on seed composition; and single nucleotide polymorphisms (SNPs) or mutations on a single base pair within the soybean genome that have large effects on seed composition.
The source of most QTLs is unknown, but they are assumed to be due to random mutations in the soybean genome that happen from generation to generation. In contrast to QTLs, SNPs are known mutations that were bred into a cultivar at some point in its domestication history. For example, there is an SNP for reduced saturated fatty acids in high oleic acid lines that was introduced
