AI Technical Summary
Existing rice breeding methods lack efficient aggregation technology for multiple traits, making it difficult to simultaneously improve high yield, quality, disease resistance, and stress tolerance. Furthermore, existing molecular marker technologies mainly focus on improving single traits, making it difficult to achieve synergistic improvement of multiple traits in a short period of time.
By employing genome-wide association analysis combined with marker-assisted selection (MAG) technology, stable and highly reproducible SNP markers were screened out by identifying SNP markers that were significantly associated with multiple traits. Then, marker-assisted selection and genome-wide selection were performed to achieve efficient aggregation and stable transmission of multiple traits.
To achieve synergistic optimization of multiple target traits in rice, such as high yield, high quality, disease resistance, and stress tolerance, in a short period of time, thereby improving breeding efficiency and ensuring the predictability and long-term stability of breeding results.
