AI Technical Summary
Existing technologies cannot accurately assess the weight of green pecans during the seedling stage, resulting in long breeding cycles and low efficiency. The lack of closely linked SNP markers and efficient detection systems hinders the breeding and promotion of large-fruited varieties.
We developed SNP molecular markers for the weight of unripe pecans and constructed a corresponding efficient detection system. We used high-throughput sequencing technology to identify relevant biomarkers and applied them to MAS breeding and GS models to achieve accurate assessment and prediction of unripe pecan weight during the seedling stage.
It enables precise assessment of seedling green fruit weight, reduces breeding costs, shortens the breeding cycle, accelerates the cultivation and promotion of large-fruited varieties, and improves breeding efficiency and seedling screening efficiency.
