Introduction:
Soybean is an important legume crop and a leading source of dietary protein and oil in animal feed, as well as an important food for human consumption. The objective of our research was to study soybean genetic resources in context of future protein self-sufficiency both in human and animal nutrition.
Methods:
Collection of 360 different accessions from various regions worldwide was evaluated across four European locations during two consecutive years in phenotyping trials. The five most important traits of soybean - plant emergence, plant length, protein content, seed yield, and R8 stage - were carefully analysed, revealing significant variability.
Results:
Ten exceptionally stable genotypes were identified based on their protein content and yield, presenting promising candidates for breeding programs.
Discussion:
Our findings underscore the importance of integrating genotype-environment interaction analyses into breeding initiatives, considering the observed variability in phenotypic traits across diverse environments and genotypes.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...
Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
