Hypothesis
The study aims to unravel the genetic architecture of traits relevant for tofu production to assess the potential of marker-assisted selection and genomic selection in breeding for these traits.
Conclusion
Inheritance of tofu quality traits is highly quantitative, and both marker-assisted selection and genomic selection present valuable tools to advance tofu quality by soybean breeding.
Supporting Evidence
- QTL mapping identified QTL for all investigated agronomic and quality traits.
- Four QTL identified for tofu hardness jointly explained 68.7% of the genotypic variation.
- Genomic selection revealed moderate to high mean prediction accuracies for all traits, ranging from 0.47 to 0.78.
- Tofu yield and hardness showed a strong negative correlation (r = -0.65).
Takeaway
This study looks at how to make better tofu from soybeans by understanding the genes that affect tofu quality, which can help farmers grow better soybeans for tofu.
Methodology
QTL mapping was performed with 188 genotypes from a biparental mapping population evaluated in a two-location field trial.
Potential Biases
The phenotyping process for tofu quality is labor-intensive and may introduce variability due to environmental factors.
Limitations
The study's findings may not be transferable to other populations due to the specific genetic background of the mapping population.
Participant Demographics
The study involved a biparental mapping population of soybean genotypes.
